“How much does SEO cost” doesn’t have a single answer because the scope of “SEO” varies enormously between providers and projects. What actually drives price is more useful to understand.
What Drives the Price
- Competition level — ranking a local service business in a small city costs far less than competing nationally in a saturated category.
- Site condition — a technically sound site needs less foundational work than one requiring a full audit and rebuild first.
- Content volume — ongoing content production scales cost with output.
- Scope — technical-only work costs less than a full technical + content + link-building program.
Common Pricing Models
Monthly retainers are most common for ongoing work; project-based pricing suits one-off audits or migrations; hourly rates are less common but occur for smaller, defined tasks.
Red Flags
Guaranteed #1 rankings, prices far below market average with no explanation of scope, and vague reporting are the most common signs of a low-quality provider. See our SEO agency buyer checklist for a fuller list.
