200+ Google Ranking Factors: What Is Confirmed, Likely or Myth

This page is for site owners, writers and SEOs who keep meeting “200 ranking factors” lists and want to know which items deserve their time. You will be able to see what Google has actually confirmed, test yourself with a short quiz, and work through the confirmed factors on your own site in the order I use on audits.

Google uses hundreds of signals to rank pages, but it has never published a list of 200 ranking factors. That number started as industry shorthand. What Google does describe, in its How Search Works pages, are the broad groups: meaning, relevance, quality, usability and context, with the weight of each factor varying by query. Below I go through more than 200 commonly cited factors and label each one honestly: Confirmed (Google has said so), Likely (strong evidence, not officially stated), Unconfirmed (speculation), Myth (Google has denied it or there is no evidence) or Historical (true once, changed since).

Earlier versions of lists like this one quoted precise percentages for almost every factor. I removed them, because most of those figures could not be traced to a real study, and correlation studies cannot prove what Google rewards anyway.

How to read the status labels

Every factor below carries one of five labels. I based them on what Google has said in its documentation, blog posts and public statements, on the systems named in its guide to ranking systems, and on well-documented evidence such as trial testimony. Here is how the 203 entries on this page break down:

Two caveats. Confirmed does not mean strong: HTTPS is confirmed but light. And a high count in one row says nothing about weight. A handful of confirmed factors, such as relevance and content quality, outweigh dozens of minor ones put together.

What changed in Google ranking recently

• Helpful content folded into core ranking (March 2024): there is no separate helpful content update any more; the same idea runs inside the core systems. My write-up of the March 2024 core update explains what changed.
• New spam policies (March 2024): scaled content abuse, site reputation abuse and expired domain abuse were added. I list them in the webspam section below.
• INP replaced FID (March 2024): Interaction to Next Paint is now the Core Web Vitals responsiveness metric. See my INP guide.
• Mobile-first indexing finished (July 2024): Google now crawls almost every site with its smartphone crawler.
• AI Overviews and AI Mode: AI answers now sit above many results, so clear, well-sourced answers matter for being cited, not only for ranking.
• Retired tools and features: the Mobile-Friendly Test, the Structured Data Testing Tool (use the Rich Results Test and Schema Markup Validator), HowTo rich results, and FAQ rich results for most sites.
• Click data: testimony in the 2023 US antitrust trial and the 2024 leaked API documents showed Google uses click and interaction data (NavBoost) in some form.

The 8 factors most lists rank highest

These are the eight factors most ranking-factor lists put at the top. I have kept them in that familiar order, but read the status lines: two of the eight do not hold up as ranking factors at all.

1. Quality Content
   • Google prioritizes high-quality, informative, and engaging content. Content that satisfies user intent, provides value, and is well-researched ranks higher.
   • Tip: Write original, people-first content that fully answers the query.
   • Status: Confirmed. Google says its automated ranking systems are designed to prioritise helpful, reliable information created to benefit people.
2. Backlinks
   • Backlinks act like votes of confidence from other websites. Links from relevant, trusted sites remain one of the clearest signals Google has.
   • Tip: Build backlinks from authoritative, relevant websites.
   • Status: Confirmed. Google confirms it uses links to discover pages and judge relevance, though it has said links matter less than they once did.
3. Technical SEO
   • A technically sound website is essential for ranking. This includes fast loading speed, mobile-friendliness, crawlability, and proper indexing.
   • Tip: Use tools like Google Search Console to identify and fix technical issues.
   • Status: Confirmed. Pages must be crawlable and indexable to rank at all; HTTPS and speed are confirmed but light signals.
4. Keyword Optimization
   • Using relevant keywords in your content helps Google understand your page’s topic. However, avoid keyword stuffing.
   • Tip: Include keywords in title tags, headers, and meta descriptions.
   • Status: Confirmed. Google describes words on the page matching the query as the most basic relevance signal.
5. User Experience (UX)
   • Google rewards websites that offer a seamless, enjoyable user experience. This includes easy navigation, fast load times, and mobile optimization.
   • Tip: Use Core Web Vitals to improve UX.
   • Status: Confirmed. Google says page experience aligns with what its core systems reward, but it is not one single ranking system.
6. Schema Markup
   • Schema markup is a type of structured data that helps Google better understand your content. It can also enhance your search listings with rich snippets.
   • Tip: Implement schema for articles, products, organisations and breadcrumbs, and validate it with the Rich Results Test.
   • Status: Myth. Structured data is not a ranking factor. It makes pages eligible for rich results. HowTo rich results were removed in 2023 and FAQ rich results now show only for authoritative government and health sites.
7. Social Signals
   • Google says social shares, likes and engagement are not a direct ranking factor, but they can indirectly help by driving traffic and increasing visibility.
   • Tip: Promote your content on social media platforms.
   • Status: Myth. Google has repeatedly said social shares and likes are not a direct ranking factor.
8. Brand Signals
   • A strong brand presence online can improve your rankings. This includes brand searches, mentions, and a recognizable online identity.
   • Tip: Build your brand through consistent messaging and visibility.
   • Status: Unconfirmed. There is no confirmed brand score, but strong brands earn links, mentions and branded searches, which do help.

Domain-Level Factors

These factors relate to your website’s domain and can influence its authority and trustworthiness:

1. Domain Age
   • Older domains are often assumed to be more trustworthy, but Google has stated that domain age alone is not a ranking factor.
   • Tip: Focus on building a strong domain reputation over time.
   • Status: Myth. Google’s John Mueller has said domain age helps nothing on its own.
2. Keyword in Top-Level Domain (TLD)
   • Having a keyword in your domain (e.g., bestcoffee.com) can act as a relevancy signal, though its impact has diminished over time.
   • Tip: Choose a domain name that’s brandable and easy to remember.
   • Status: Historical. Google’s 2012 exact-match domain update reduced the value of keywords in low-quality domains. Expect little or no boost today.
3. Domain Registration Length
   • Domains registered for multiple years are seen as more legitimate compared to those registered for just one year.
   • Tip: Register your domain for at least 2-3 years.
   • Status: Unconfirmed. Mentioned in an old Google patent, but Google has said it is not something site owners need to worry about.
4. Keyword in Subdomain
   • A keyword in your subdomain (e.g., blog.bestcoffee.com) can provide a slight relevancy boost.
   • Tip: Use subdomains strategically for specific content categories.
   • Status: Unconfirmed. Any boost is small at best; choose subdomains for structure, not for keywords.
5. Domain History
   • A domain with a clean history (no penalties or spammy activity) is more likely to rank well.
   • Tip: Use tools like Wayback Machine to check a domain’s history before purchasing.
   • Status: Likely. Past spam on a domain can take time to clear, so check its history before buying.
6. Exact Match Domains (EMDs)
   • Exact match domains (e.g., buycoffee.com) no longer provide a significant ranking boost and can be vulnerable to penalties if the content is low-quality.
   • Tip: Focus on branding and user experience over exact match domains.
   • Status: Historical. The 2012 EMD update targeted low-quality exact-match domains. A good site on an EMD can still rank.
7. Public vs. Private WhoIs
   • A long-standing belief holds that public WhoIs signals transparency and private WhoIs raises red flags.
   • Tip: Keep your WhoIs information public and accurate.
   • Status: Myth. Google has said private WhoIs is not a negative signal in itself.
8. Penalized WhoIs Owner
   • If the domain owner has a history of spammy behavior, it may negatively impact the domain’s rankings.
   • Tip: Ensure your domain is registered under a clean, reputable entity.
   • Status: Unconfirmed. Speculative. Google has not confirmed using owner history across domains.
9. Country Code Top-Level Domain (ccTLD)
   • Using a ccTLD (e.g., .uk, .ca) can help with local rankings but may limit global visibility.
   • Tip: Use a ccTLD if you’re targeting a specific country.
   • Status: Confirmed. Google uses ccTLDs for geotargeting. Search Console’s International Targeting report was retired in 2022, so ccTLDs and hreflang do this job.

Page-Level Ranking Factors

These ranking factors relate to individual pages on your website and their optimization:

1. Keyword in Title Tag
   • The title tag is one of the most important on-page SEO elements. Including your target keyword here can improve rankings.
   • Tip: Place the keyword near the beginning of the title tag.
   • Status: Confirmed. Title elements are a confirmed relevance signal, though Google may rewrite title links it finds unhelpful.
2. Title Tag Starts with Keyword
   • Titles that start with the target keyword tend to perform better than those where the keyword appears at the end.
   • Tip: Keep titles under 60 characters to avoid truncation in search results.
   • Status: Unconfirmed. Front-loading the keyword can help readers scan, but Google has not confirmed a position effect.
3. Keyword in Meta Description
   • While not a direct ranking factor, a well-written meta description can improve click-through rates (CTR), which indirectly impacts rankings.
   • Tip: Write compelling meta descriptions that include your target keyword.
   • Status: Myth. Google confirms meta descriptions are not used for ranking; they can affect clicks, and Google often rewrites them.
4. Keyword in H1 Tag
   • The H1 tag acts as a secondary title tag and helps Google understand the page’s content.
   • Tip: Use a clear, descriptive H1 that matches the topic.
   • Status: Likely. Google says headings help it understand page structure. It has also said more than one H1 on a page is fine.
5. Content Length
   • Longer content can rank well when the topic needs depth, but length alone does not help.
   • Tip: Write as much as the topic needs, in content that answers user queries.
   • Status: Myth. Google says word count is not a ranking factor. Length should follow what the query needs.
6. Table of Contents
   • A linked table of contents improves user experience and helps Google understand the page’s structure.
   • Tip: Use a table of contents for long-form content.
   • Status: Unconfirmed. A table of contents can earn jump links in results, but it is not a ranking factor.
7. Latent Semantic Indexing (LSI) Keywords
   • Related terms and subtopics help Google understand the context of your content.
   • Tip: Include related terms and synonyms naturally in your content.
   • Status: Myth. Google does not use Latent Semantic Indexing. Covering related subtopics and entities, the idea behind semantic SEO, is what actually helps.
8. Page Loading Speed
   • Fast-loading pages rank higher and provide a better user experience.
   • Tip: Optimize images, use a CDN, and enable browser caching.
   • Status: Confirmed. Speed has been a signal since 2010 for desktop and 2018 for mobile, but it is a light one.
9. Use of AMP (Accelerated Mobile Pages)
   • AMP was once required for Top Stories on mobile; that requirement ended in 2021.
   • Tip: Most sites no longer need AMP; focus on a fast responsive page instead.
   • Status: Myth. AMP is not a ranking factor, and since June 2021 it is no longer required for Top Stories.
10. Duplicate Content
    • Duplicate content can harm your rankings. Ensure each page has unique, valuable content.
    • Tip: Use canonical tags to address duplicate content issues.
    • Status: Likely. There is no penalty for ordinary duplication; Google picks a canonical and filters duplicates. Copying content to manipulate rankings is a different matter.
11. Image Optimization
    • Optimized images improve page speed and provide additional ranking signals through alt text, file names, and captions.
    • Tip: Use descriptive file names and alt text for all images.
    • Status: Confirmed. Alt text, file names and surrounding text are confirmed signals for Google Images.
12. Content Recency
    • Fresh content is favored for time-sensitive queries. Regularly update your content to maintain relevance.
    • Tip: Add a “last updated” date to your content.
    • Status: Confirmed. Google’s freshness systems favour recent content for queries where freshness matters.
13. Keyword Prominence
    • Placing your keyword in the first 100 words of your content can improve relevancy.
    • Tip: Use keywords naturally and avoid over-optimization.
    • Status: Unconfirmed. Common advice, but Google has not confirmed a first-100-words effect.
14. Keyword in H2 and H3 Tags
    • Using keywords in subheadings (H2, H3) helps Google understand the structure and relevance of your content.
    • Tip: Break up long content with descriptive subheadings.
    • Status: Unconfirmed. Helpful for structure; no confirmed weighting for keywords in subheadings.
15. Outbound Link Quality
    • Linking to authoritative, relevant websites can improve your page’s credibility.
    • Tip: Avoid linking to low-quality or spammy sites.
    • Status: Unconfirmed. Google has said linking out is not a ranking factor in itself, but citing good sources helps readers trust you.
16. Grammar and Spelling
    • Proper grammar and spelling are signals of content quality. Poorly written content may rank lower.
    • Tip: Use tools like Grammarly to proofread your content.
    • Status: Unconfirmed. Google has said grammar is not a direct factor, but poor writing hurts perceived quality.
17. Syndicated Content
    • If your content is copied from another source, it may not rank well. Google prioritizes original content.
    • Tip: Publish unique content and use canonical tags if syndicating.
    • Status: Confirmed. Google may rank the syndicated copy instead of the original. Since 2023 Google recommends partners use noindex rather than relying on canonical tags.
18. Mobile-Friendly Design
    • With the mobile-first index, Google prioritizes mobile-friendly websites.
    • Tip: Use responsive design and test your site with Lighthouse in Chrome DevTools.
    • Status: Confirmed. Mobile-first indexing now covers almost all sites. Google retired the Mobile-Friendly Test and the Mobile Usability report in December 2023, so test with Lighthouse instead.
19. Hidden Content on Mobile
    • An older belief held that content hidden behind tabs or accordions on mobile was weighted less.
    • Tip: Tabs are fine for Google; just make sure critical content is easy for users to find.
    • Status: Myth. Under mobile-first indexing Google says content inside tabs and accordions is treated as normal content.
20. Helpful Supplementary Content
    • Tools like calculators, converters, and interactive features can improve user experience and signal quality.
    • Tip: Add useful tools to your site where relevant.
    • Status: Likely. Google’s quality rater guidelines value helpful supplementary content.
21. Number of Outbound Links
    • Pages stuffed with outbound links look low quality to readers.
    • Tip: Keep outbound links relevant and moderate.
    • Status: Myth. There is no confirmed ideal number of outbound links.
22. Multimedia Content
    • Images, videos, and infographics can enhance user engagement and act as content quality signals.
    • Tip: Use optimized multimedia to support your content.
    • Status: Unconfirmed. Images and video can help users and earn extra search features; no direct boost is confirmed.
23. Internal Linking
    • Linking to other pages on your site helps Google understand your site’s structure and hierarchy.
    • Tip: Use descriptive anchor text for internal links.
    • Status: Confirmed. Google uses internal links to discover pages and understand how they relate.
24. Broken Links
    • Too many broken links can signal a neglected site.
    • Tip: Regularly audit your site for broken links using tools like Screaming Frog.
    • Status: Unconfirmed. Google says 404s are normal and do not hurt the rest of the site. Fix broken internal links for users and crawling.
25. Reading Level
    • Google can estimate the reading level of your content. Simple, easy-to-read content often performs better.
    • Tip: Write for your target audience’s reading level.
    • Status: Unconfirmed. Not confirmed. Write at the level your audience needs.
26. Affiliate Links
    • Excessive affiliate links can trigger Google’s spam filters.
    • Tip: Balance affiliate links with valuable, non-monetized content.
    • Status: Likely. Affiliate links are fine when tagged rel=”sponsored”; thin affiliate pages with no added value are what get demoted.
27. HTML Errors
    • Poorly coded HTML can harm your site’s performance and rankings.
    • Tip: Validate your HTML using tools like the W3C Markup Validation Service.
    • Status: Myth. Google has said valid HTML is not a ranking factor, as long as the page renders and can be parsed.
28. Domain Authority
    • Pages on high-authority domains tend to rank higher than those on low-authority domains.
    • Tip: Build your site’s authority through quality content and backlinks.
    • Status: Myth. Domain Authority is a Moz metric. Google does not use it, although it does assess some site-wide signals.
29. PageRank
    • PageRank, no longer shown publicly, is still part of Google’s algorithm.
    • Tip: Focus on earning high-quality backlinks to improve PageRank.
    • Status: Confirmed. Google confirms PageRank is still used, but the public toolbar score was retired in 2016, so there is no score to check.

Site-Level Ranking Factors

These factors relate to your website as a whole and its overall structure:

1. Site Architecture
   • A well-organized site structure helps Google crawl and index your pages efficiently.
   • Tip: Use a silo structure to group related content.
   • Status: Likely. A clear structure helps crawling and internal link flow.
2. Site Updates
   • Regularly updating your site with fresh content can improve rankings.
   • Tip: Add a blog or news section to keep your site dynamic.
   • Status: Unconfirmed. Updating for its own sake does not help; updating to keep content accurate does.
3. Presence of Sitemap
   • A sitemap helps Google discover and index your pages.
   • Tip: Submit your sitemap to Google Search Console.
   • Status: Confirmed. Sitemaps help discovery, but Google says they are not a ranking factor.
4. Site Uptime
   • Frequent downtime can harm your rankings and user experience.
   • Tip: Use a reliable hosting provider and monitor uptime.
   • Status: Confirmed. Short outages are tolerated; long or repeated downtime can lead to pages dropping out of the index.
5. Server Location
   • Hosting your site on a server close to your target audience can improve load times and local rankings.
   • Tip: Use a CDN to serve content faster globally.
   • Status: Myth. Google relies on ccTLDs, hreflang and content for geotargeting far more than server location.
6. SSL Certificate
   • HTTPS is a ranking signal and improves user trust.
   • Tip: Migrate your site to HTTPS if you haven’t already.
   • Status: Confirmed. HTTPS has been a lightweight ranking signal since 2014.
7. E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness)
   • Google prioritizes sites that demonstrate expertise, authoritativeness, and trustworthiness.
   • Tip: Showcase credentials, citations, and testimonials.
   • Status: Likely. E-E-A-T (Experience was added in December 2022) comes from the quality rater guidelines. It is not a single factor, but Google’s systems look for signals that align with it.
8. Duplicate Meta Information
   • Duplicate meta titles and descriptions can harm your site’s visibility.
   • Tip: Use unique meta tags for every page.
   • Status: Unconfirmed. Duplicate titles and descriptions make pages harder to tell apart; no direct penalty.
9. Breadcrumb Navigation
   • Breadcrumbs improve user experience and help Google understand your site’s structure.
   • Tip: Implement breadcrumb markup for better indexing.
   • Status: Confirmed. Breadcrumb markup is used in desktop results. Since January 2025 Google no longer shows breadcrumbs in mobile results.
10. Mobile Optimization
    • A mobile-optimized site is essential for ranking in the mobile-first index.
    • Tip: Test your site with Lighthouse in Chrome DevTools.
    • Status: Confirmed. See mobile-friendly design above; mobile-first indexing applies to almost every site.
11. YouTube Integration
    • YouTube videos often rank well in search results, especially for visual content.
    • Tip: Embed relevant YouTube videos on your site.
    • Status: Unconfirmed. YouTube videos can appear in video results, but embedding them gives no confirmed boost.
12. Site Usability
    • A user-friendly site improves engagement and rankings.
    • Tip: Simplify navigation and reduce clutter.
    • Status: Likely. Usability supports the page experience Google says it rewards.
13. Google Analytics and Search Console
    • While not direct ranking factors, these tools provide valuable data for optimizing your site.
    • Tip: Regularly review performance metrics in these tools.
    • Status: Myth. Google says it does not use Google Analytics data for ranking. Universal Analytics has been replaced by GA4.
14. User Reviews and Reputation
    • Positive reviews and a strong online reputation can boost rankings.
    • Tip: Encourage satisfied customers to leave positive reviews.
    • Status: Confirmed. Reviews are a confirmed local ranking input; for organic results the link is indirect.
15. Core Web Vitals
    • Core Web Vitals (loading, interactivity, visual stability) are critical ranking factors.
    • Tip: Optimize for Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS).
    • Status: Confirmed. The Core Web Vitals are LCP, INP and CLS. Interaction to Next Paint replaced First Input Delay in March 2024.

Backlink Ranking Factors

Backlinks remain one of the most important ranking factors. Here’s what matters:

1. Linking Domain Age
   • Backlinks from older domains may carry more weight.
   • Tip: Focus on earning links from established websites.
   • Status: Unconfirmed. No confirmed effect from the age of the linking domain.
2. Number of Linking Root Domains
   • The more unique domains linking to you, the better.
   • Tip: Diversify your backlink profile.
   • Status: Likely. Correlation studies consistently tie more referring domains to higher rankings. Backlinko’s analysis of 11.8 million results found the top result averaged 3.8 times more backlinks than positions 2 to 10, though correlation does not show cause.
3. Links from Separate C-Class IPs
   • Links from different IP ranges signal a natural link profile.
   • Tip: Avoid links from the same network.
   • Status: Unconfirmed. An old SEO idea; Google has not confirmed IP diversity as a factor.
4. Number of Linking Pages
   • Multiple links from the same domain can still provide value.
   • Tip: Focus on contextual links within content.
   • Status: Unconfirmed. Further links from the same site tend to add less value.
5. Backlink Anchor Text
   • Keyword-rich anchor text can improve relevancy, but avoid over-optimization.
   • Tip: Use a mix of branded and keyword-rich anchor text.
   • Status: Confirmed. Google uses anchor text to understand the linked page; heavily optimised anchors are a classic link spam pattern.
6. Alt Text for Image Links
   • Alt text acts as anchor text for image links.
   • Tip: Use descriptive alt text for all images.
   • Status: Confirmed. Google uses the alt text of a linked image as its anchor text.
7. Links from .edu or .gov Domains
   • Links from educational or government sites can boost authority.
   • Tip: Seek opportunities for natural links from these domains.
   • Status: Myth. Google has said .edu and .gov links get no special weight because of their TLD.
8. Authority of Linking Page
   • Links from high-authority pages pass more value.
   • Tip: Focus on earning links from topically relevant, authoritative pages.
   • Status: Likely. PageRank flows from linking pages, so stronger pages pass more.
9. Links from Competitors
   • Links from competitors in the same niche can be highly valuable.
   • Tip: Analyze competitor backlinks and replicate their strategies.
   • Status: Unconfirmed. Speculative.
10. Links from “Expected” Websites
    • Google may expect certain authoritative sites in your niche to link to you.
    • Tip: Build relationships with industry leaders to earn natural links.
    • Status: Unconfirmed. Speculative, based on patent discussion rather than Google statements.
11. Links from Bad Neighborhoods
    • Links from spammy or low-quality sites can harm your rankings.
    • Tip: Regularly audit your backlink profile and disavow toxic links.
    • Status: Confirmed. Google says it mostly ignores spammy links. Use the disavow tool only for links you built or after a manual action.
12. Guest Posts
    • While guest posting can build links, excessive or low-quality guest posts may trigger penalties.
    • Tip: Focus on high-quality, relevant guest posts.
    • Status: Confirmed. Google’s spam policies say links in guest posts made mainly for links should be qualified with nofollow or sponsored.
13. Links from Ads
    • Links from ads should be marked with rel=sponsored to avoid penalties.
    • Tip: Use nofollow or sponsored attributes for ad links.
    • Status: Confirmed. Paid and ad links must carry rel=”sponsored” or rel=”nofollow”.
14. Homepage Authority
    • Links to your homepage can boost overall domain authority.
    • Tip: Ensure your homepage is well-optimized and link-worthy.
    • Status: Unconfirmed. Not confirmed as a separate factor.
15. Nofollow Links
    • While nofollow links don’t pass PageRank, they can still drive traffic and signal relevance.
    • Tip: Maintain a natural mix of follow and nofollow links.
    • Status: Confirmed. Since 2020 Google treats nofollow as a hint, so it may still use these links.
16. Diversity of Link Types
    • A natural backlink profile includes links from blogs, directories, forums, and social media.
    • Tip: Avoid over-reliance on a single link type.
    • Status: Unconfirmed. A natural profile tends to be varied, but variety itself is not a confirmed factor.
17. Sponsored or UGC Tags
    • Links marked as rel=sponsored or rel=UGC are treated differently by Google.
    • Tip: Use the appropriate attributes for sponsored and user-generated content.
    • Status: Confirmed. rel=”sponsored” and rel=”ugc” were introduced in 2019 and are treated as hints.
18. Contextual Links
    • Links embedded within content are more valuable than standalone links.
    • Tip: Focus on earning contextual, editorial links.
    • Status: Likely. Editorial links within content are widely believed to carry more weight than boilerplate links.
19. Excessive 301 Redirects
    • Long redirect chains slow crawling and users.
    • Tip: Use direct links whenever possible.
    • Status: Confirmed. Google has said 301 and other redirects do not lose PageRank. Avoid long chains, as Googlebot follows up to 10 hops.
20. Internal Link Anchor Text
    • Internal links with keyword-rich anchor text can improve page relevance.
    • Tip: Use descriptive anchor text for internal links.
    • Status: Confirmed. Internal anchor text helps Google understand the target page.
21. Link Title Attribution
    • The title attribute of a link can provide additional context.
    • Tip: Use descriptive titles for all links.
    • Status: Myth. The link title attribute is not used for ranking.
22. Country TLD of Referring Domain
    • Links from country-specific domains can boost local rankings.
    • Tip: Target links from local, relevant domains.
    • Status: Unconfirmed. Can help local relevance, but not confirmed.
23. Link Location in Content
    • Links placed early in the content may carry more weight.
    • Tip: Position important links near the top of the page.
    • Status: Unconfirmed. Not confirmed.
24. Link Location on Page
    • Links in the main content area are more valuable than those in the footer or sidebar.
    • Tip: Prioritize content-embedded links.
    • Status: Likely. Patents describe weighting links by how likely they are to be clicked, so main-content links likely count more than footer links.
25. Linking Domain Relevancy
    • Links from topically relevant domains are more valuable.
    • Tip: Focus on earning links from sites in your niche.
    • Status: Likely. Links from relevant sites are generally treated as stronger signals.
26. Page-Level Relevancy
    • Links from relevant pages pass more value.
    • Tip: Ensure linking pages are topically aligned with your content.
    • Status: Likely. Relevance of the linking page appears to matter.
27. Keyword in Title of Linking Page
    • Links from pages with your keyword in the title can boost relevance.
    • Tip: Seek links from topically aligned pages.
    • Status: Unconfirmed. Speculative.
28. Positive Link Velocity
    • A steady increase in backlinks signals growing popularity.
    • Tip: Focus on consistent link-building efforts.
    • Status: Unconfirmed. No confirmed effect; natural growth matters more than speed.
29. Negative Link Velocity
    • A sudden drop in backlinks can harm rankings.
    • Tip: Monitor your backlink profile for unusual changes.
    • Status: Unconfirmed. Losing links can lower rankings simply because the signals are gone.
30. Links from “Hub” Pages
    • Links from pages considered hubs for a topic can boost rankings.
    • Tip: Target links from authoritative resource pages.
    • Status: Unconfirmed. Speculative, based on older patents.
31. Links from Authority Sites
    • Links from well-known, trusted sites carry more weight.
    • Tip: Build relationships with industry leaders.
    • Status: Likely. Links from trusted sites tend to pass more value.
32. Linked to as Wikipedia Source
    • While Wikipedia links are nofollow, they can still boost credibility.
    • Tip: Ensure your site is cited as a reliable source.
    • Status: Myth. Wikipedia links are nofollow and pass no PageRank, though citations can bring traffic and further links.
33. Co-Occurrences
    • The words surrounding your backlinks provide context.
    • Tip: Focus on earning links from topically relevant content.
    • Status: Unconfirmed. Speculative; often discussed alongside entity understanding.
34. Backlink Age
    • Older backlinks may carry more weight than new ones.
    • Tip: Build long-term, sustainable links.
    • Status: Unconfirmed. Not confirmed.
35. Links from Real Sites vs. Splogs
    • Links from genuine sites are more valuable than those from spammy blogs.
    • Tip: Avoid links from low-quality or automated sites.
    • Status: Confirmed. Links from spam blogs and link networks are ignored or count against you under Google’s spam policies.
36. Natural Link Profile
    • A diverse, natural link profile is more durable to algorithm updates.
    • Tip: Avoid black-hat link-building tactics.
    • Status: Confirmed. Google’s spam policies target manipulative link patterns, so a natural profile is safer.
37. Reciprocal Links
    • Excessive link exchanges can trigger penalties.
    • Tip: Keep reciprocal links natural and moderate.
    • Status: Confirmed. Excessive link exchanges are listed in Google’s spam policies.
38. User-Generated Content Links

    • Tip: Use rel=UGC for links in user-generated content.
    • Status: Confirmed. Links in comments and forums should use rel=”ugc”.
39. Links from 301 Redirects
    • An older belief held that links through 301 redirects lose value.
    • Tip: Use direct links whenever possible.
    • Status: Confirmed. Google has said redirects pass PageRank, so links to redirected URLs still count.

User Interaction Ranking Factors

Google uses user behavior data to assess content quality and relevance:

1. RankBrain
   • Google’s machine-learning system that helps relate searches to the concepts behind them.
   • Tip: Focus on user satisfaction and engagement.
   • Status: Confirmed. RankBrain is a confirmed machine-learning system (2015) that helps relate searches to concepts. It is not something you optimise for directly.
2. Organic Click-Through Rate (CTR)
   • Pages with higher CTRs may rank higher.
   • Tip: Write compelling titles and meta descriptions.
   • Status: Likely. Evidence from the 2023 US antitrust trial and the 2024 leaked API documents shows Google uses click data (NavBoost), though not as a simple CTR score.
3. Bounce Rate
   • A high bounce rate can signal poor content or user experience.
   • Tip: Improve content relevance and usability.
   • Status: Myth. Google does not use Analytics bounce rate, and GA4 replaced it with engagement rate as the main metric.
4. Direct Traffic
   • Sites with high direct traffic are seen as more authoritative.
   • Tip: Build brand awareness and loyalty.
   • Status: Unconfirmed. Not confirmed; Google says it does not use Analytics data.
5. Repeat Traffic
   • Users returning to your site signal high engagement.
   • Tip: Encourage repeat visits through email marketing and notifications.
   • Status: Unconfirmed. Not confirmed.
6. Pogosticking
   • Users bouncing back to search results after visiting your site can harm rankings.
   • Tip: Ensure your content fully satisfies user intent.
   • Status: Likely. Related to the click data described in NavBoost; returning quickly to results may suggest the page did not satisfy the search.
7. Dwell Time
   • Longer time spent on your site signals high-quality content.
   • Tip: Create engaging, in-depth content.
   • Status: Unconfirmed. Google has said dwell time is not a direct ranking factor.
8. Blocked Sites
   • Sites blocked by users in Chrome may lose rankings.
   • Tip: Ensure your site is user-friendly and trustworthy.
   • Status: Historical. The Chrome site-blocking feature from 2011 no longer exists.
9. Chrome Bookmarks
   • Pages bookmarked by users may receive a rankings boost.
   • Tip: Encourage users to bookmark your site.
   • Status: Myth. There is no evidence that bookmarks affect rankings.
10. Number of Comments
    • Pages with active discussions signal engagement.
    • Tip: Encourage user interaction and comments.
    • Status: Unconfirmed. An active community can signal a healthy site, but comment counts are not a confirmed factor.

Special Google Algorithm Rules

Google’s algorithm includes specific rules and updates that influence rankings:

1. Query Deserves Freshness (QDF)
   • For time-sensitive queries, Google prioritizes recently published or updated content.
   • Tip: Regularly update content for trending or seasonal topics.
   • Status: Confirmed. Google’s freshness systems surface newer content for queries that need it.
2. Query Deserves Diversity (QDD)
   • For ambiguous queries, Google diversifies results to cover different interpretations.
   • Tip: Optimize for multiple intents if your keyword is ambiguous.
   • Status: Likely. Google diversifies results for ambiguous queries.
3. User Browsing History
   • Google personalizes results based on a user’s browsing history.
   • Tip: Build brand loyalty to encourage repeat visits.
   • Status: Confirmed. Google personalises lightly, mostly by location and recent context.
4. User Search History
   • Previous searches influence future results for the same user.
   • Tip: Focus on long-term user engagement.
   • Status: Confirmed. Recent searches can shape results for the same person, but the effect is small.
5. Featured Snippets
   • Pages that answer clearly can be chosen for featured snippets and cited in AI Overviews.
   • Tip: Use structured data and concise answers to target snippets.
   • Status: Myth. A featured snippet is a way of displaying a result, not a ranking factor. AI Overviews and AI Mode now answer many queries above or beside these results.
6. Geo-Targeting
   • Google prioritizes local results for geo-specific queries.
   • Tip: Use local SEO strategies like Google Business Profile.
   • Status: Confirmed. Location strongly shapes local results.
7. Safe Search
   • Adult content or explicit material is filtered out for users with Safe Search enabled.
   • Tip: Avoid inappropriate content to maintain visibility.
   • Status: Confirmed. SafeSearch filters explicit content for users who have it on.

9. DMCA Complaints
   • Pages with valid DMCA complaints may be downranked.
   • Tip: Avoid copyright infringement and use original content.
   • Status: Confirmed. Sites with many valid copyright removal notices can be demoted.
10. Domain Diversity
    • Google limits the number of results from a single domain for broad queries.
    • Tip: Focus on quality over quantity for domain visibility.
    • Status: Confirmed. Google’s site diversity system (2019) generally shows no more than two results from one site in the top results.
11. Transactional Searches
    • Google displays shopping results for transactional queries.
    • Tip: Optimize for Google Shopping if you sell products.
    • Status: Confirmed. Shopping features appear for product queries.
12. Local Searches
    • Local businesses are prioritized for location-based queries.
    • Tip: Optimize your Google Business Profile.
    • Status: Confirmed. Local packs appear for location-based queries.
13. Top Stories Box
    • News articles appear in the Top Stories box for relevant queries.
    • Tip: Use Google News SEO best practices for news content.
    • Status: Confirmed. Top Stories favours fresh news; AMP has not been required since 2021.
14. Big Brand Preference
    • Google often favors big brands for competitive keywords.
    • Tip: Build brand authority to compete with established players.
    • Status: Unconfirmed. Brands tend to win because they earn the signals above, not because of a brand bonus.
15. Shopping Results
    • Google Shopping ads and organic listings appear for product-related queries.
    • Tip: Use product schema markup to enhance visibility.
    • Status: Confirmed. Google has offered free product listings since 2020, driven by Merchant Center feeds and product structured data.

    • Optimized images can appear in Google’s image search and organic results.
    • Tip: Use descriptive file names and alt text.
    • Status: Confirmed. Images can appear in Google Images and in image packs.
17. Easter Egg Results
    • Google occasionally includes fun, interactive results for specific queries.
    • Tip: Ignore these for SEO; they are novelty features.
    • Status: Myth. Easter eggs are novelty features, not ranking factors.
18. Single Site Results for Brands
    • Branded queries often display multiple results from the same domain.
    • Tip: Build a strong brand presence to dominate SERPs.
    • Status: Confirmed. Branded searches often show sitelinks and several results from the brand’s own site.
19. Payday Loans Update
    • This update targets spammy queries like payday loans and casinos.
    • Tip: Avoid black-hat tactics for high-risk niches.
    • Status: Historical. The Payday Loans update (2013) targeted very spammy queries.

Brand Signals

Google uses brand-related signals to assess a site’s authority and trustworthiness:

1. Brand Name Anchor Text
   • Links using your brand name as anchor text signal brand authority.
   • Tip: Encourage branded backlinks.
   • Status: Unconfirmed. Branded anchors look natural, but there is no confirmed boost.
2. Branded Searches
   • Users searching for your brand name indicate brand recognition.
   • Tip: Build brand awareness through marketing.
   • Status: Unconfirmed. Not confirmed by Google, though leaked documents and patents suggest brand demand is tracked.
3. Brand + Keyword Searches
   • Searches combining your brand with a keyword signal relevance.
   • Tip: Optimize for branded and non-branded keywords.
   • Status: Unconfirmed. Not confirmed.
4. Facebook Page and Likes
   • A strong Facebook presence can enhance brand signals.
   • Tip: Engage with your audience on social media.
   • Status: Myth. Google has said Facebook likes are not a ranking factor.
5. X (formerly Twitter) Profile and Followers
   • A popular X profile is often assumed to signal brand authority.
   • Tip: Share valuable content to grow your following.
   • Status: Myth. Google has said follower counts on X (formerly Twitter) are not a ranking factor.
6. LinkedIn Company Page
   • A professional LinkedIn presence boosts credibility.
   • Tip: Maintain an active LinkedIn profile.
   • Status: Myth. Not a ranking factor, though a profile can rank for your brand name.
7. Known Authorship
   • Content from verified authors may rank higher.
   • Tip: Use author markup to highlight content creators.
   • Status: Likely. Google Authorship markup was dropped in 2014. Clear bylines, author pages and Person markup support E-E-A-T instead.
8. Legitimacy of Social Media Accounts
   • Fake or inactive social accounts can harm brand signals.
   • Tip: Maintain authentic, active social profiles.
   • Status: Unconfirmed. Not confirmed.
9. Brand Mentions in Top Stories
   • Mentions in news articles signal brand authority.
   • Tip: Build relationships with journalists and influencers.

10. Unlinked Brand Mentions
    • Mentions of your brand without links still signal authority.
    • Tip: Monitor and encourage brand mentions.
    • Status: Unconfirmed. Not confirmed; patents describe implied links, but Google has not said it uses them.
11. Brick-and-Mortar Location
    • A physical address adds legitimacy to your brand.
    • Tip: Include your business address on your site.
    • Status: Confirmed. A real address and a verified Google Business Profile matter for local rankings.

On-Site Webspam Ranking Factors

These practices appear in Google’s spam policies for web search, which say sites that break them may rank lower or not appear in results at all:

1. Panda Penalty
   • Low-quality or thin content can trigger a Panda penalty.
   • Tip: Focus on high-quality, original content.
   • Status: Historical. Panda became part of the core algorithm in 2016, and Google’s helpful content system was folded into core ranking in March 2024.
2. Links to Bad Neighborhoods
   • Linking to spammy sites can harm your rankings.
   • Tip: Regularly audit outbound links.
   • Status: Unconfirmed. Not confirmed, but linking to spam reflects badly on a page.

   • Tip: Use transparent, user-friendly redirects.
   • Status: Confirmed. Sneaky redirects violate Google’s spam policies.
4. Popups and Distracting Ads
   • Intrusive popups can harm user experience and rankings.
   • Tip: Use non-intrusive ad placements.
   • Status: Confirmed. Google’s page experience guidance warns against intrusive popups.
5. Interstitial Popups
   • Full-page popups on mobile devices can trigger penalties.
   • Tip: Avoid intrusive interstitials.
   • Status: Confirmed. Google’s 2017 intrusive interstitials update targets mobile pages that block content.
6. Site Over-Optimization
   • Excessive keyword stuffing or optimization can lead to penalties.
   • Tip: Focus on natural, user-focused content.
   • Status: Confirmed. Keyword stuffing is listed in Google’s spam policies. My guide to keyword density and stuffing shows how to spot it.
7. Gibberish Content
   • Auto-generated or nonsensical content is penalized.
   • Tip: Write clear, meaningful content.
   • Status: Confirmed. Gibberish and spammy auto-generated text violate Google’s spam policies.
8. Doorway Pages
   • Pages created solely to rank for specific keywords are penalized.
   • Tip: Create user-focused, valuable pages.
   • Status: Confirmed. Doorway pages violate Google’s spam policies.
9. Ads Above the Fold
   • Excessive ads above the fold can harm user experience.
   • Tip: Balance ads with valuable content.
   • Status: Confirmed. Google’s page layout algorithm (2012) targets pages with too many ads above the fold.
10. Hiding Affiliate Links
    • Cloaking affiliate links is a violation.
    • Tip: Disclose affiliate links and use rel=sponsored.
    • Status: Confirmed. Cloaking violates Google’s spam policies; disclose affiliate links and tag them rel=”sponsored”.
11. Fred Update
    • The Fred update targets low-value content created primarily for revenue.
    • Tip: Prioritize user value over monetization.
    • Status: Historical. Fred was an unofficial name for a 2017 update that hit thin, ad-heavy content.
12. Affiliate Sites
    • Sites with excessive affiliate links may face penalties.
    • Tip: Balance affiliate content with original, valuable content.
    • Status: Confirmed. Thin affiliate pages that add nothing are demoted; strong affiliate content can still rank.
13. Autogenerated Content
    • Mass-produced content generated to manipulate rankings is penalised.
    • Tip: Publish original, genuinely helpful content, however it is drafted.
    • Status: Confirmed. Google’s scaled content abuse policy (March 2024) targets mass-produced pages made to rank rather than help, whether written by AI or people.
14. Excessive PageRank Sculpting
    • Overuse of nofollow links to control PageRank can trigger penalties.
    • Tip: Use nofollow links sparingly and appropriately.
    • Status: Historical. Nofollow sculpting stopped working in 2009; it now just wastes PageRank.
15. IP Address Flagged as Spam
    • Hosting on a server with spammy sites can harm your rankings.
    • Tip: Choose a reputable hosting provider.
    • Status: Myth. Google says sharing a server with spammy sites is not a problem in itself.
16. Meta Tag Spamming
    • Keyword stuffing in meta tags is a violation.
    • Tip: Write natural, descriptive meta tags.
    • Status: Confirmed. Stuffing keywords into meta tags is spam. Google has ignored the meta keywords tag since 2009.

Off-Site Webspam Ranking Factors

Google also evaluates off-site signals to identify spammy behavior:

1. Hacked Site
   • If your site is hacked, it may be deindexed or penalized.
   • Tip: Regularly monitor and secure your site.
   • Status: Confirmed. Hacked content can lead to warnings in results and removal from the index.
2. Unnatural Influx of Links
   • A sudden spike in backlinks can signal manipulative practices.
   • Tip: Build backlinks naturally and gradually.
   • Status: Likely. Large, sudden influxes of low-quality links match common link scheme patterns.
3. Penguin Penalty
   • The Penguin update targets sites with manipulative link-building practices.

   • Status: Historical. Since 2016 Penguin runs in real time and mainly devalues spammy links rather than demoting whole sites.
4. High Percentage of Low-Quality Links
   • A backlink profile dominated by low-quality links can harm rankings.
   • Tip: Regularly audit and disavow toxic links.
   • Status: Likely. Google mostly ignores low-quality links, but a profile built on them can lead to a manual action.
5. Links from Unrelated Websites
   • Links from topically unrelated sites may be seen as spammy.
   • Tip: Focus on relevant, niche-specific backlinks.
   • Status: Unconfirmed. Irrelevant links tend to be ignored rather than penalised.

   • Links from multiple sites on the same server can signal a link network.
   • Tip: Diversify your backlink sources.
   • Status: Unconfirmed. Not confirmed.
10. “Poison” Anchor Text
    • Links with spammy or irrelevant anchor text can harm your site.
    • Tip: Monitor and disavow toxic anchor text.
    • Status: Unconfirmed. Spammy anchors pointing at a site are often a sign of hacking or negative SEO, which Google says it mostly ignores.
11. Unnatural Link Spike
    • A sudden increase in backlinks may trigger algorithmic penalties.
    • Tip: Build links organically over time.
    • Status: Likely. See unnatural influx of links above.
12. Links from Article Directories and Press Releases

    • Status: Confirmed. Selling links that pass PageRank violates Google’s spam policies.
15. Google Sandbox
    • New sites may experience delayed rankings due to the sandbox effect.
    • Tip: Focus on building authority and trust.
    • Status: Myth. Google denies a sandbox. New sites rank slowly because they have few signals yet.
16. Google Dance
    • Temporary ranking fluctuations may occur during algorithm updates.
    • Tip: Stay consistent with white-hat SEO practices.
    • Status: Historical. An old term for ranking swings. Today, check Google’s Search Status Dashboard for confirmed updates.
17. Disavow Tool
    • Use the disavow tool to remove harmful backlinks.
    • Tip: Regularly audit your backlink profile.
    • Status: Confirmed. The disavow tool exists, but Google says most sites never need it.

    • Status: Confirmed. Added to Google’s spam policies in March 2024.
21. Site Reputation Abuse
    • Third-party pages hosted on a trusted site to borrow its ranking strength, such as coupon or casino sections on news sites.
    • Tip: Keep third-party content closely tied to your site’s purpose and editorially controlled.
    • Status: Confirmed. Enforced since May 2024, and Google clarified in November 2024 that first-party involvement does not make it acceptable.
22. Expired Domain Abuse
    • Buying an expired domain and filling it with low-value content to exploit its old reputation.
    • Tip: If you buy an old domain, use it for something closely related to what it was.
    • Status: Confirmed. Added to Google’s spam policies in March 2024.

Additional Ranking Factors

These factors may indirectly influence rankings or are speculative:

1. Domain Diversity in Backlinks
   • A diverse backlink profile signals natural link-building.
   • Tip: Earn links from various types of sites.
   • Status: Likely. Varied referring domains correlate with stronger rankings.
2. Social Media Engagement
   • While not a direct ranking factor, social signals can drive traffic.
   • Tip: Promote your content on social platforms.
   • Status: Myth. Not a direct ranking factor; social activity can lead to links and visits.
3. Content Updates
   • Regularly updating content can improve freshness and rankings.
   • Tip: Add new insights and data to existing content.
   • Status: Confirmed. Updating content keeps it accurate for queries that need freshness. Changing only the date does not help.
4. Internal Search Data
   • Google may use data from its search engine to refine rankings.
   • Tip: Focus on user intent and satisfaction.
   • Status: Likely. Google uses its own interaction data, as the NavBoost evidence shows.

8. Core Web Vitals
   • Metrics like LCP, INP and CLS impact user experience and rankings.
   • Tip: Optimize for fast loading and interactivity.
   • Status: Confirmed. The Core Web Vitals are LCP, INP and CLS. INP replaced FID in March 2024.
9. Page Experience Signals
   • Google considers overall page experience in rankings.
   • Tip: Focus on speed, mobile-friendliness, and security.
   • Status: Confirmed. Google said in 2023 that page experience is not one single ranking system, but its core systems reward good experience.
10. E-E-A-T for YMYL Sites
    • Experience, Expertise, Authoritativeness and Trustworthiness are critical for YMYL sites.
    • Tip: Showcase credentials and citations.
    • Status: Likely. E-E-A-T matters most for YMYL topics, according to the quality rater guidelines.
11. Local SEO Signals
    • For local businesses, factors like reviews and proximity matter.
    • Tip: Optimize your Google Business Profile.
    • Status: Confirmed. Google confirms local rankings depend on relevance, distance and prominence. If you are new to this, start with local SEO for beginners.

    • Video content can enhance engagement and rankings.
    • Tip: Embed relevant videos on your site.
    • Status: Unconfirmed. Video can earn extra search features; no direct ranking boost is confirmed.
13. Podcast and Audio Content
    • Audio content can support a topic when it has a text version.
    • Tip: Transcribe and optimize audio content.
    • Status: Unconfirmed. Google Podcasts closed in 2024. Transcripts help because they turn audio into text Google can read.
14. Voice Search Optimization
    • Voice search queries often differ from text-based searches.
    • Tip: Optimize for natural language and long-tail keywords.
    • Status: Myth. Voice assistants mostly read from normal results; there is no separate voice ranking factor.
15. AI-Generated Content
    • While AI tools can assist, low-quality AI content may harm rankings.
    • Tip: Use AI to enhance, not replace, human creativity.
    • Status: Confirmed. Google says AI-assisted content is fine when it is helpful; mass-produced low-value pages fall under its scaled content abuse policy.
16. Multilingual SEO
    • Optimizing for multiple languages can expand your reach.
    • Tip: Use hreflang tags for multilingual sites.
    • Status: Confirmed. hreflang and separate URLs per language are Google’s recommended set-up.
17. Accessibility
    • Accessible sites improve user experience and rankings.
    • Tip: Follow WCAG guidelines for accessibility.
    • Status: Myth. Accessibility is not a direct ranking factor, but it overlaps with good page experience.
18. Structured Data
    • Schema markup can make pages eligible for rich results.
    • Tip: Implement structured data for key content types.
    • Status: Myth. Structured data does not raise rankings; it makes pages eligible for rich results, several of which Google has reduced since 2023.
19. Content Clusters
    • Grouping related content improves topical authority.
    • Tip: Create pillar pages and supporting content.
    • Status: Likely. Covering a topic in depth with linked pages helps relevance and internal linking.
20. User-Generated Content
    • UGC can boost engagement and rankings.
    • Tip: Encourage reviews, comments, and contributions.
    • Status: Unconfirmed. User-generated content can add useful detail, but spammy UGC hurts.
21. Influencer Partnerships
    • Collaborating with influencers can drive traffic and backlinks.
    • Tip: Partner with relevant, authentic influencers.
    • Status: Unconfirmed. Partnerships help only if they lead to real mentions and links; paid links must be tagged rel=”sponsored”.
22. Content Personalization
    • Personalized content improves user engagement.
    • Tip: Use dynamic content based on user behavior.
    • Status: Myth. Not a ranking factor.
23. Zero-Click Searches and AI Overviews
    • Google often answers on the results page, through featured snippets, AI Overviews and AI Mode, reducing clicks to websites.
    • Tip: Answer questions clearly and early so your page can be shown or cited in featured snippets and AI Overviews.
    • Status: Confirmed. AI Overviews (2024) and AI Mode (2025) now answer many queries on the results page. Being cited in them depends on the same quality and relevance signals.
24. Algorithmic Updates

    • Tip: Stay informed about algorithm changes.
    • Status: Confirmed. Google confirms several core updates a year on its Search Status Dashboard.
25. Long-Term SEO Strategy
    • Sustainable SEO requires ongoing effort and adaptation.
    • Tip: Focus on long-term growth and user value.
    • Status: Myth. Not a factor in itself; it is simply how SEO works.

How I use this list on an audit

When I audit a site, I start with the confirmed factors that are usually broken, not with the long tail. In my experience the problems that hold sites back are rarely exotic: pages that cannot be crawled or indexed, content that does not match what the searcher wants, weak internal linking, and thin or duplicated pages. Only once those are fixed do I look at links and brand signals. The unconfirmed and myth items are useful mainly so you can recognise, and ignore, advice built on them.

The checklist below is the order I work in. Each line maps to confirmed or likely factors from the sections above.

A common mistake I see

The most expensive mistake I find is a team working through a 200-item list from the top, spending weeks on items such as WhoIs privacy, outbound link counts or keyword-in-subdomain tweaks while key pages are not indexed or do not match search intent. A shorter list of confirmed factors, done properly, beats a long list done evenly.
