How This Comparison Was Compiled

AireStream wrote this page, and AireStream is one of the nine agencies on it. We have not ranked the list or scored any agency, including ourselves, and the agencies appear in alphabetical order.

Every detail comes from the agency's own website or from a public record such as Companies House, checked in September 2026. If the only source for a figure was a competitor's website, we left it out. If an agency publishes figures about its own performance, we say so.

There is no independent ranking of AI SEO agencies in the UK. Several agencies describe themselves as the first or the leading GEO agency in the country, and no independent body verifies claims like these. Treat any numbered list of the best AI SEO agencies, including ones that rate us highly, as the view of whoever published it.

AireStream

Leeds · AI search visibility only

Our own entry. A UK AI SEO agency based in Leeds, built around ACTIVE GEO, our audit methodology. We test 100 buyer questions across ChatGPT, Claude, Gemini, Perplexity and Copilot, score 73 components across five sections and deliver the findings as an interactive report. Our programmes run for three months and finish with a full re-test against the original baseline.

Published pricing: AI Visibility Benchmark £500. Programmes £1,400 and £2,000 per month for three months. One-off audits £3,000 and £4,800.

Blue Array

Reading · SEO, GEO and digital PR

An established organic search agency that offers generative engine optimisation as a named service alongside SEO and digital PR. It is a certified B Corporation, which you can confirm in B Lab's public directory. Likely to suit businesses that want AI search handled by the same team already running their SEO.

Buried

United Kingdom · GEO, SEO and AI search

An organic search agency that presents generative engine optimisation as a core discipline alongside SEO and AI search strategy, rather than as an extension of existing SEO work.

Exposure Ninja

United Kingdom · SEO, content and digital PR

An established digital marketing agency working across SEO, content and digital PR, with AI search included in that wider offer. Likely to suit businesses that want one agency across several channels rather than a standalone AI visibility engagement.

Found

London · Integrated digital marketing, including GEO

A London digital marketing agency whose SEO, paid media, data and digital PR teams work together, with generative engine optimisation included in that offer. It describes its approach as Everysearch. Likely to suit businesses already running paid and organic search together who want AI search reported in the same place.

Impression

Nottingham and London · Integrated search

An integrated search agency working across SEO, digital PR, paid media and analytics, with AI search included within that offer. Best suited to organisations running substantial programmes across several channels at once.

MarGen

London · GEO and AEO for regulated sectors

A B2B agency specialising in GEO and AEO for UK regulated industries: financial services, legal, healthcare and construction. It describes its approach as a proprietary methodology built around the content and citation standards those sectors demand. Worth a look if you work in one of them.

Rank4AI

United Kingdom · AI search visibility only

A pure-play AI search agency that does not offer traditional SEO retainers or paid media, and works with clients across several UK cities. Engagements begin with an audit across six AI platforms. Registered as Rank4AI Ltd in England and Wales, company number 16584507, which you can confirm at Companies House.

Published pricing: From £800 per month for the ecosystem service and from £1,500 per month for the full agency service, as published on their site.

Tilio

United Kingdom · AEO and GEO as one programme

Sells answer engine optimisation and generative engine optimisation together as a single programme. It publishes its own visibility figures for the agency category; those figures are measured by Tilio, so treat them as marketing rather than independent data.

Published pricing: From £499 per month, as published on their site.

Choosing

How to Choose a Top AI SEO Agency

Whichever agencies you shortlist, four questions will tell you most of what you need to know.

How many questions do you test, and who writes them?

A baseline built from a dozen generic prompts says very little. The questions should cover every service you sell and be worded the way your buyers actually ask. AireStream tests 100 questions across five AI search engines, written in your buyers' language and confirmed by you.

Can I see the raw responses?

A visibility score on its own cannot be checked. The verbatim answers show which businesses are being recommended in your place, and why, which is usually more useful than the score. AireStream's report includes the verbatim response from every AI search engine to every question.

Do you test my competitors?

Knowing your own score is useful. Knowing where named competitors are ahead of you, and on which components, tells you what to fix first. The AireStream AI Advantage Programme runs the full 73-component audit on up to three competitors you name.

How will we know it worked?

Ask whether the engagement ends with a re-test against the original numbers, or simply continues into another month. The answer tells you whether the agency expects to be measured. AireStream programmes end with a month-three re-test against your month-one baseline.

Questions

Choosing an AI SEO Agency, Answered

There is no independent ranking of AI SEO agencies. Most published lists are written by an agency that features on them, and AireStream is one of the nine on this page. The agencies here are a cross-section of UK agencies currently offering AI SEO, listed alphabetically. The right choice depends on whether you want an AI search specialist, an agency that runs it alongside your existing SEO, or a specialist in your sector.

If your SEO agency already knows your site and has the capacity, adding AI search to that relationship is usually simpler and cheaper. A specialist makes more sense when you want AI search measured properly and separately, or when your current agency treats it as a small extension of keyword work.

Four questions tell you most of what you need to know: how many buyer questions they test and who writes them, whether you can see the verbatim AI responses rather than only a score, whether they test your named competitors, and whether the engagement ends with a re-test against the original numbers.

Where agencies publish prices, they currently start at around £499 per month and rise to £1,500 per month or more for full-service work. Others quote after an initial conversation. Some, including AireStream, also sell one-off audits. Compare what is included rather than the monthly figure, and in particular whether a re-test is part of the price.

They describe overlapping work. GEO (generative engine optimisation) and AEO (answer engine optimisation) are the terms many agencies use for improving how a business appears in AI-generated answers. AI SEO is the broader term most buyers search for. All three share the same goal: being recommended when someone asks an AI search engine to recommend a business.
