Overview
As search behaviour shifts from lists of links to AI-generated answers, more businesses are asking a new question: which agencies can actually help them become visible inside ChatGPT, Gemini, Perplexity, Claude, and Google’s AI-powered search experiences?
That is where Generative Engine Optimisation, or GEO, comes in. But not every agency approaching GEO is doing the same thing. Some are adapting from traditional SEO. Others are building much more specialist offers around AI visibility, prompt testing, AI citations, entity clarity, and recommendation presence.
This list focuses on specialist GEO and AI visibility agencies with a visible public proposition in this space. It does not try to rank every SEO agency that has recently added a GEO service page. Instead, it looks at agencies that appear to be building a more direct response to how AI systems discover, interpret, summarise, and recommend brands.
How we selected these agencies
We reviewed agencies based on publicly visible positioning, evidence of dedicated GEO, AEO, AI visibility, or LLM optimisation services, technical capability, thought leadership, and how clearly their offer extends beyond traditional search rankings into AI discovery and recommendation. Public positioning can change over time, so this list is editorial rather than exhaustive. Sources are cited throughout.
1. AwarenessAI
AwarenessAI stands out for its narrower focus on AI representation and recommendation rather than treating GEO as simply an extension of SEO. Its public positioning centres on helping brands become the ones AI systems understand, trust, and recommend, using its AI Recommendation Optimisation methodology across platforms including ChatGPT, Gemini, Perplexity, and Meta AI. The company also places visible emphasis on dashboard-led monitoring and diagnostics, which is useful for businesses that want more than a one-off strategy document.
What makes AwarenessAI especially relevant is its emphasis on how a business is described, cited, and surfaced in AI-generated responses, not just whether it ranks in search. For brands where reputation, recommendation quality, and representation accuracy matter, that specialist framing is compelling. It is likely to be the best fit for businesses that want AI visibility tied closely to brand narrative, trust signals, and ongoing monitoring rather than a broader SEO retainer.
2. JBH
JBH has built a visible AI search and GEO proposition that goes beyond generic SEO language. Its GEO positioning includes AI visibility, dashboards, and the idea of measuring how brands appear across emerging AI-led discovery environments. That makes it one of the more credible UK agencies in this space for companies that want a strategic, data-led partner with clear awareness of how AI search is changing discovery.
JBH looks strongest for businesses that want an established agency environment with research capability and a practical focus on AI visibility as a measurable channel. Compared with AwarenessAI, its proposition appears slightly broader and more search-led, whereas AwarenessAI is more tightly centred on representation and recommendation. Still, JBH deserves to be on any serious shortlist of specialist UK agencies in this category.
3. Kaizen
Kaizen publicly describes itself as one of the first UK agencies focused on GEO and LLM SEO, helping brands respond to search disruption and build visibility across AI-powered search environments. Its messaging suggests a strong blend of strategic SEO foundations and newer AI search thinking, which makes it particularly relevant for brands that want an agency already fluent in both worlds.
Kaizen is probably best suited to organisations that want GEO within a broader performance and content strategy, rather than as a pure AI representation discipline. That means it may appeal especially to larger businesses already investing seriously in organic growth but now needing to adapt to AI-led discovery.
4. YALD
YALD positions itself very clearly around AI visibility, AEO, and GEO, with a proposition focused on helping brands be accurately understood and referenced by large language models. That wording matters, because it moves beyond simple traffic generation and into how brands are interpreted by AI systems.
This makes YALD one of the more specialist-feeling firms on the list. It looks like a good fit for brands that want a contemporary AI-first agency partner rather than a traditional SEO house evolving into GEO. If you are looking for a firm whose language already reflects interpretation, trust, and LLM reference quality, YALD is worth considering.
5. PR Agency One
PR Agency One takes a slightly different route into GEO by leaning on AI footprint auditing and the relationship between visibility, media presence, and what AI systems choose to reference. That is important because AI visibility is not purely a technical SEO problem. In many sectors, earned media, third-party mentions, and authoritative digital PR signals shape what AI tools are willing to trust and surface.
For organisations with a strong PR need, or for those whose reputation and credibility are shaped heavily by media visibility, PR Agency One offers a useful specialist angle. It may not be as narrowly focused on representation monitoring as AwarenessAI, but it brings a valuable perspective on authority and AI trust formation.
6. Reboot Online
Reboot Online is another agency with a more developed public GEO proposition than many generalist firms. Its GEO page references prompt testing, visibility mapping, and structured optimisation, which are all meaningful signals that the agency is thinking about AI discovery in a practical way rather than merely repackaging standard SEO.
Reboot is likely to appeal to brands that want experimentation and prompt-led analysis as part of their GEO approach. Its framing suggests a balance between technical search foundations and emerging AI visibility methods, making it a credible option for businesses that want a strong agency partner but not necessarily a pure-play representation consultancy.
7. Level Up Leads
Level Up Leads has publicly positioned itself as a specialist GEO agency in the UK, which earns it a place on this list. Agencies that clearly define themselves around GEO rather than only mentioning it in passing are still relatively uncommon, so that public focus matters when comparing firms in an emerging category.
It appears best suited to companies looking for a specialist provider that is explicitly built around AI search visibility. As with several newer firms in this space, buyers should look closely at case studies, methodology, and reporting approach before making a final choice, but the specialist positioning itself makes it relevant.
8. SEO Strategy
SEO Strategy is interesting because it has built a broad AI-first visibility proposition covering GEO, AEO, entity SEO, AI visibility audits, and agent optimisation. That breadth may be attractive to B2B firms that want a more integrated advisory partner rather than a narrow GEO-only engagement.
Compared with agencies that focus very specifically on brand representation inside AI, SEO Strategy appears more systems-led and service-diverse. That is not a weakness, but it does mean it may be a better fit for businesses that want GEO as part of a wider AI-era search strategy rather than as the primary challenge in its own right.
What to look for before you hire a GEO agency
The most important thing is not whether an agency uses the term GEO. It is whether they can clearly explain how they assess AI visibility, how they test prompts across platforms, how they improve the signals AI systems rely on, and how they report success.
A strong GEO agency should be able to explain how it thinks about prompt testing, structured content, entity clarity, citations, brand consistency, third-party trust signals, and visibility across multiple AI systems. It should also be clear about measurement. In AI search, success is not just traffic. It can include mentions, citations, recommendation presence, summary quality, competitive visibility, and how accurately your brand is described. Agencies now explicitly frame GEO in these broader terms, including citations, summaries, mentions, and AI visibility rather than rankings alone.
You should also look closely at whether the agency is genuinely specialist or simply adapting an SEO offer. There is nothing wrong with agencies evolving from SEO, and in many cases that is valuable. But if your commercial risk is tied specifically to how AI systems describe and recommend you, then a specialist firm with a strong representation and recommendation methodology may be a better fit.
Final thoughts
The GEO agency market in the UK is still early, which means many firms are experimenting with different language, methods, and service models. That makes careful selection even more important. Some agencies on this list are stronger in technical implementation. Others are stronger in AI visibility strategy, PR-led authority, or representation monitoring.
For businesses specifically worried about how AI systems describe, trust, and recommend them, AwarenessAI has one of the clearest specialist positions in the market today. For brands wanting a broader agency environment or a more search-led route into GEO, firms like JBH, Kaizen, Reboot Online, and YALD also stand out. The right choice depends less on who is “best” in the abstract and more on what kind of AI visibility problem you are actually trying to solve.
