Best GEO Companies in the United Kingdom (2026)
Updated
Generative engine optimization (GEO) is the practice of getting a brand cited in AI answers such as Google AI Overviews, ChatGPT and Perplexity. To be listed, an agency must publicly name GEO, AEO or LLM visibility as a service and link evidence; generic "AI-powered SEO" wording is not enough. UK agencies were plentiful, so this list is capped at eight; other UK agencies with GEO pages, such as JBH, Epic New Media and Priority Pixels, are not listed.

Frequently asked questions
- What is GEO (generative engine optimization)?
- GEO is optimizing content, structure and brand signals so AI systems such as Google AI Overviews, ChatGPT and Perplexity cite and recommend your brand in generated answers.
- How is GEO different from SEO?
- SEO targets rankings in a list of links; GEO targets being cited inside an AI-generated answer. GEO builds on strong SEO foundations such as technical health, structured data and authoritative content.
- How do you choose GEO companies in the United Kingdom?
- An agency must name GEO, AEO or LLM visibility as a service and link public evidence. Generic AI-powered SEO wording is not enough. Qualifying agencies are scored on a published rubric and the list is capped at eight.
- How much does GEO cost in the UK?
- Few agencies publish GEO prices. Reboot Online states GEO pricing from 2,500 pounds per month and Tilio lists service levels from 499 pounds a month. For the rest, expect to request a proposal.
- Can any SEO agency do GEO?
- Strong SEO is the base, but GEO adds work such as entity clarity, citation-friendly content and AI visibility tracking. Ask for a named service and examples of how visibility is measured.
- How do I measure GEO results?
- Common approaches are tracking brand mentions and citations across AI answers for a fixed question set, plus referral traffic from AI platforms. Answer engines decide what they show, so a good agency reports observed changes rather than guaranteeing citations.
How we ranked these agencies
We found candidates through web search and agency directories (Clutch, Semrush Agencies, GoodFirms and UK agency round-ups), then opened each agency's own site to confirm it lists a real office in the United Kingdom and names GEO, AEO or LLM visibility as a service with a dedicated page. Each agency is scored 1-5 in half-point steps per criterion on the GEO rubric below; the page score is the weighted average. Clutch and GoodFirms block automated access, so we could not verify third-party review counts and show none: the "Client reviews" criterion reflects named testimonials, awards and review-platform recognition shown on the agency's own site. Self-reported awards, client counts and case-study numbers are attributed to the agency, not confirmed by us. Anything we could not verify was left out.
| Criterion | Weight | What earns a 5 vs a 1 |
|---|---|---|
| GEO / AEO capability | 30% | 5 = GEO, AEO or LLM-visibility is a named, described service with a dedicated page; 1 = generic "AI-powered SEO" wording only. |
| AI visibility evidence | 20% | 5 = published methodology, tooling, research or case results for AI-search visibility; 1 = no evidence. |
| Content and technical foundation | 15% | 5 = strong underlying SEO, structured data and content practice that GEO builds on; 1 = thin foundation. |
| Client reviews | 15% | 5 = strong, sizeable third-party review profiles; 1 = none found. |
| Transparency | 10% | 5 = published process, pricing or engagement model and named team; 1 = opaque. |
| Local market fit | 10% | 5 = real local office and local-market experience; 1 = no verifiable local presence. |
