There is no single "best" GEO or AEO agency in the UK — the right choice depends on your size, sector and budget. UK agencies with credible AI-search offers in 2026 include Passion Digital, The SEO Works, Bird, POLARIS, Exposure Ninja, Varn and Found, each with different strengths. Elite Digital Agency (which publishes this comparison) suits SMBs and charities that want transparent published pricing and a named AI-search methodology. Because we are one of the agencies compared, this article is unavoidably biased — treat it as a starting shortlist and verify every agency's current claims independently.
GEO (Generative Engine Optimisation) and AEO (Answer Engine Optimisation) went from conference-talk buzzwords to line items in marketing budgets in under two years. The reason is simple: around 60% of Google searches ended without a click in 2026, according to industry zero-click research, and a growing share of buyers now ask ChatGPT, Gemini or Perplexity for recommendations instead of scrolling results. When an AI engine names three agencies, tools or suppliers in its answer, the ones it doesn't name effectively don't exist for that buyer.
Dozens of UK agencies now claim to offer GEO or AEO. Some have built genuine, named methodologies; others have relabelled their existing SEO retainer. This comparison applies the same criteria to each agency so you can shortlist fairly — including against us.
How we judged: the criteria
We assessed each agency on four criteria that a buyer can actually check from the outside, without needing a sales call. We deliberately did not score or rank the agencies — we don't have access to their client results, and any ranking we published would be invented. Instead, each criterion is rated qualitatively from what is publicly visible:
- Named methodology — does the agency describe a specific, named approach to AI search (not just "we do GEO too")? A named method suggests codified thinking you can interrogate.
- Pricing transparency — are prices or starting rates published on the website? Published pricing is still rare in this market and signals how the agency will behave commercially.
- Reviews and social proof — does the agency have a visible, third-party review footprint and verifiable company details? We note its presence, not scores.
- SMB fit — is the offer realistically accessible to a small or mid-sized UK business, or is it clearly aimed at enterprise budgets?
One more criterion sits above all of these: does the agency practise what it preaches? An agency selling AI-search visibility should itself be visible, structured and citable — direct answers, schema, transparent company details. Check their own site before you check their pitch deck.

The agencies, honestly profiled
These profiles stick to publicly known positioning. We have no inside knowledge of any competitor's delivery quality, and we haven't included review scores, client names or results we can't verify.
Passion Digital
A London full-service digital agency with a strong content-led SEO and digital PR reputation. Their strength is integrated campaigns where organic search, content and paid media need to work together, and they publish considered thinking on how AI is reshaping search. Best suited to mid-size brands and scale-ups that want one agency across several channels rather than a narrow AI-search specialist.
The SEO Works
A long-established, Sheffield-headquartered search specialist with a sizeable team and deep sector experience, including healthcare and ecommerce. Their strength is pure-play search at scale — technical SEO, content and digital PR with mature processes — and they now describe AI SEO within that offer. Suits organisations that value an established, process-driven search agency over a boutique.
Bird
A London-based agency with an international footprint, combining web development with performance marketing. Their strength is joined-up delivery — site builds, SEO and paid under one roof — which matters for AI search because so much of GEO depends on how the site itself is built. Suits businesses that want a combined web-and-marketing partner, particularly those operating across multiple markets.
POLARIS
A London SEO agency known for B2B, ecommerce and website migration work, with AI search folded into its SEO programmes. Their strength is structured, commercially focused SEO for catalogues and complex sites — exactly the environments where entity clarity and structured data pay off fastest in AI answers. Suits mid-market ecommerce and B2B brands with established organic revenue.
Exposure Ninja
A Nottingham-based agency widely known for its educational content and free website and marketing reviews, which make it one of the most accessible entry points in UK search. Their strength is SEO and PPC for small and mid-sized businesses, communicated in plain English, and they cover AI search in their content and services. Suits SMBs taking a first serious step into organic and AI search.
Varn
A Bradford-based technical search consultancy known for original research into AI Overviews and search analytics. Their strength is depth on the technical and data side — the kind of measurement and experimentation work that larger in-house teams buy in. Suits organisations that already have marketing resource and need specialist technical AI-search expertise rather than a full-service retainer.
Found
A London agency known for its Everysearch™ methodology — a named framework for search across platforms, not just Google — which is one of the few genuinely codified approaches in this market. Their strength is multi-channel search strategy for larger brands, backed by a sizeable specialist team. Suits enterprise and upper-mid-market brands with the budgets to match.
Where Elite Digital Agency fits (and our bias)
We publish this comparison and we appear in it, so read this section with that in mind — we are not a neutral referee, and no agency-published listicle is. Where we genuinely differ: we publish our pricing openly (AEO and GEO programmes from £995/month) rather than quoting behind a sales call; our AI-search work runs on a named, public methodology — the C.I.T.E. Framework™ (Crawlability, Intent-chunking, Trust signals, Entity corroboration) — so you can inspect the method before you buy it; we specialise in SMBs and registered charities, with a 20% charity discount and Google Ad Grants management; and we maintain free tools, including a GEO audit, so you can test our thinking on your own site before spending anything.
Where we are not the right fit: very large enterprise programmes, heavy multi-market international rollouts, and brands that need a big agency team on-site. In those cases, one of the larger agencies above will serve you better. Whatever you shortlist, verify current claims, pricing and methodology directly with each agency — this market is moving fast and any article, including this one, ages quickly.
What to ask any GEO or AEO agency before hiring
- How do you measure AI visibility? Ask for the specific method — which engines, which queries, how often — and be wary of "trust us" answers.
- Can you show the methodology, not just the slide deck? A named, public method (like Found's Everysearch™ or our C.I.T.E. Framework™) can be interrogated; a proprietary black box cannot.
- What will you change on our website in month one? Real GEO/AEO work touches robots.txt, schema, content structure and entity data almost immediately.
- Do you guarantee AI citations? If yes, walk away — no agency controls what ChatGPT or Google AI Overviews output; honest agencies maximise and measure probability.
- What does it cost, in writing? Insist on published or written pricing with deliverables attached, and check what happens to your site, content and data if you leave.
- How does this integrate with our SEO? GEO without technical SEO and content foundations is decoration; the disciplines should share one strategy.
Six AI-readiness dimensions, an instant score and prioritised fixes — no sign-up, under a minute.
Not quite — but the overlap is large. Roughly 70% of GEO is excellent SEO: technical health, structured content, topical authority. The genuinely new layer is entity corroboration (consistent identity across Companies House, LinkedIn, reviews and third-party citations), answer-first content chunking designed for extraction rather than ranking, and measuring citations inside AI answers rather than positions in a results page. Be sceptical of agencies selling GEO as a wholly separate, expensive bolt-on — the foundations are shared and should be priced that way.
UK GEO/AEO programmes typically run £800–£3,000 per month, usually bundled with SEO because the foundations overlap. Standalone AI-visibility audits are sold as one-off projects. Treat any quote well above that range with suspicion unless it includes substantial content production or digital PR, and treat very cheap offers as relabelled SEO checklists. Elite Digital Agency's AEO programmes start from £995/month with published pricing — whichever agency you choose, insist on written deliverables attached to the fee.
