Transparent 2025 data on SEO agency fees, what different budget levels deliver, and how to evaluate whether your SEO investment is working.
SEO pricing for small businesses varies enormously, from £200 per month from freelancers to £5,000 or more from full-service agencies. The question is not just what it costs, but what different levels of investment realistically deliver and over what timescale.
For service businesses, the most relevant way to evaluate SEO cost is against the cost per enquiry generated. Once SEO produces a consistent organic enquiry flow, the marginal cost per additional lead approaches zero.
Below £400 per month, the level of work possible is unlikely to produce meaningful results in competitive local markets. Worse, very cheap SEO often relies on tactics (low-quality links, thin content) that can damage your domain long-term. The risk-adjusted ROI of very cheap SEO is negative for most businesses.
The key metrics are organic enquiry volume (calls and form submissions from organic search), organic impressions and clicks in Google Search Console, and keyword ranking movements. Position tracking alone is insufficient. Ask your SEO agency to show you organic enquiry data.
