The Google March 2024 spam update started on 5 March 2024 and finished on 20 March 2024, a rollout of just under 15 days. It launched alongside three new spam policies: scaled content abuse, expired domain abuse and site reputation abuse, with site reputation abuse enforcement held back until May. If your site lost most of its traffic or dropped out of the index in March 2024, this, not the core update, is the first thing to check.
This entry is part of my full list of Google algorithm updates. Because the three policies it introduced still define how Google treats mass-produced content today, I go through each one, then show how to diagnose a hit and recover.

What the March 2024 spam update changed
There were really two things launched on 5 March 2024. One was a routine algorithmic spam update, improving Google’s automated spam detection across the board. The other, more important for most site owners, was a set of three new policies that redefined what Google counts as spam. Google also issued manual actions in parallel, which appeared in Search Console.
Scaled content abuse
This policy covers producing large numbers of pages mainly to manipulate rankings rather than help users. The key change was the wording: it applies regardless of whether the content is produced “through automation, human efforts” or a combination. Google’s older policy focused on automatically generated content. The new one closed the gap for content farms using cheap human writers, and made clear that the method does not matter, the purpose and value do.
In practice, the patterns I see in audits that fall under this heading are:
- Hundreds of AI-written articles published with little or no editing, fact-checking or original input.
- Location or keyword template pages where only the place name or keyword changes.
- Content stitched together from other sources with nothing added.
- Large batches of pages on topics unrelated to the site, published to catch search traffic.
Using AI is not itself a violation. Publishing at scale without adding value is.
Expired domain abuse
This covers buying an expired domain and repurposing it to manipulate rankings with low-value content, trading on the reputation and links the old site built. A typical example is an old charity or school domain bought and filled with affiliate or gambling content. Buying an expired domain to run a genuine, relevant business is not the problem; using its history as a shortcut for unrelated low-value content is.
Site reputation abuse
Often called parasite SEO: third-party pages published on a reputable host site to exploit its ranking signals with little first-party oversight, such as coupon, affiliate or casino sections on news sites. Google announced it on 5 March but gave site owners two months’ notice, with enforcement from 5 May 2024. I cover that separately in the site reputation abuse policy article.
Timeline
| Date | What happened |
|---|---|
| 5 March 2024 | Spam update and March 2024 core update launched; three new spam policies announced |
| Early March 2024 | Wave of pure-spam manual actions and full deindexing reported on some AI-generated and scaled-content sites (reported) |
| 20 March 2024 | Spam update rollout complete |
| 19 April 2024 | March 2024 core update rollout complete |
| 5 May 2024 | Site reputation abuse enforcement began |
Who was affected
As reported by industry observers, the most visible casualties were sites that received pure-spam manual actions shortly after launch and were removed from the index entirely. Many of these were sites built on AI-generated or mass-produced content. Google did not publish a list.
Beyond that, the algorithmic spam update targeted spam broadly, and its effects were hard to separate from the core update running for 45 days from the same date. Sites that follow Google’s spam policies were not meant to be affected by the spam update itself.
How to tell if the March 2024 spam update hit your site
The spam side of March 2024 usually looks different from the core side. Spam problems tend to be sharp and severe; core problems tend to be gradual and spread out.
- Open the Manual actions report. In Search Console, under Security and manual actions. A “pure spam” or “scaled content abuse” style action means a reviewer found a violation. This is the clearest signal there is.
- Check indexing. Run a
site:search and check the Pages report. A site that suddenly shows few or no indexed pages in March 2024 was almost certainly hit by spam enforcement. - Look at the shape of the drop. A cliff between 5 and 20 March, with most clicks gone within days, fits spam. A slope through March and April fits the core update.
- Audit your publishing history. How many pages did you publish in the 12 months before March 2024, and how? If the answer involves bulk AI generation, bought content packs or templates, compare that section’s performance with hand-written pages.
- Check the domain’s history. If you bought the domain after it expired, look at what it used to be in an archive service. A big topic change is relevant to the expired domain abuse policy.
- Rule out other causes. Tracking changes, a migration, or a noindex accidentally pushed live can all look like a penalty.
How to recover from the March 2024 spam update
Google’s advice for spam is to find the violating practice or content and remove it. Then the route depends on whether you have a manual action.
If you have a manual action
- Read the action carefully, including the example URLs it gives.
- Fix the problem across the whole site, not just the examples. For scaled content, that usually means removing the mass-produced pages rather than lightly editing them.
- File a reconsideration request in Search Console explaining what you found, what you removed or changed, and how you will prevent it recurring. Be specific; vague requests tend to be rejected.
- Wait for the response. If rejected, read the reply, fix what remains and try again.
If there is no manual action
Algorithmic spam demotions do not appear in Search Console and have no reconsideration request. You fix the issue and wait. Google says improvement may come if its automated systems learn “over a period of months” that the site complies.
What to fix, by policy
| Policy | What I look for | Fix |
|---|---|---|
| Scaled content abuse | Bulk AI or template pages, no editing, no original input, off-topic batches | Remove them (404/410) or noindex; keep only pages you would publish if search did not exist; rewrite the few worth keeping with real expertise |
| Expired domain abuse | Domain repurposed for unrelated low-value content | Stop the unrelated publishing; build a genuine site on the topic, or move the project to a fresh domain without redirects |
| Site reputation abuse | Third-party sections with little oversight | Remove, noindex, or move to a separate site (see the dedicated article) |
| Other spam (cloaking, hacked, link schemes) | Injected pages, user-agent tricks, paid links | Clean, harden and remove, then wait or request review |
A note on the content you keep
Removing scaled content is necessary but not sufficient. The March 2024 core update was running at the same time, with a stated goal of reducing unoriginal content in results. The pages you keep need to clear that bar too: clear authorship, original detail and a reason to exist. My on-page optimisation services cover rewriting the pages worth saving, and if spammy links came with the old setup, off-page SEO work can clean up the link profile.
Is it still relevant today?
Very much. The update itself finished on 20 March 2024, but the three policies it introduced are still part of Google’s spam policies and are applied in every later spam update and by manual reviewers. Scaled content abuse in particular matters more every year as AI writing tools make publishing at volume cheap. The question Google asks is not “was this written by AI?” but “was this produced at scale mainly to rank, without adding value?” If you plan any large content programme, design it to pass that test from the start.
Frequently asked questions
When did the March 2024 spam update finish?
Google marked it complete on 20 March 2024, 14 days and 21 hours after it started on 5 March 2024.
What is scaled content abuse?
Producing many pages mainly to manipulate search rankings rather than help users. Google’s policy applies whether the content is made through automation, human effort or both.
Does Google penalise AI-generated content?
Not for being AI-generated. The scaled content abuse policy targets mass-produced, low-value content regardless of how it was made. AI content that is edited, accurate and genuinely useful is treated like any other content.
My site was deindexed in March 2024. What should I do?
Check Search Console for a manual action. If there is one, remove the violating content across the site and file a detailed reconsideration request. If there is none, check for accidental noindex tags or robots.txt blocks before assuming a penalty.
How long does recovery from a spam update take?
Manual actions can be lifted after a successful reconsideration request. For algorithmic demotions, Google says improvement may take a period of months after the site complies.
