An independent UK directory of SEO and AI search agencies plus a side-by-side comparison framework. Filter by sector, city, budget, and AI platform coverage.
Compare UK SEO agencies on a side-by-side scorecard with eight columns: starting price, minimum contract, sector specialism, named lead consultant, two case studies in your vertical, AI search platform coverage, reporting cadence, and paid-audit option.

Why use an independent directory
SEO agency rankings on most directories are paid placements or affiliate-funded. SEOCompare publishes its evaluation methodology, discloses any commercial relationships, and lists agencies whether or not they pay to be featured. SEOCompare has a commercial relationship with Rank4AI; this does not change Rank4AI's placement on category pages where it is not a fit.
Use the matcher for a personalised shortlist
The agency matcher takes your sector, budget, and AI platform priorities and returns three to five UK agencies that fit. Or request a free AI visibility audit to benchmark your current AI search performance before briefing any agency.
