“Best for” is our reading of each agency’s own website, read 13 November 2026.
New to the terms? Read what AI SEO services actually include first. Prolinkage is an agency too, so we have not ranked ourselves; chapter 9 explains how we approach AI search optimisation, separately from the five.
Why trust this AI SEO agency list.
We counted names across lists instead of giving opinions. Nine of the ten ranking pages in Google’s UK top 10 are written by an agency that puts itself first, so no list counts for its own author.
Searches: “ai seo agency uk”, “best ai seo agency uk” and “geo agency uk”, Google UK, desktop. Every fact about an agency comes from its own website, read on 13 November 2026.
The first count uses the ten Google UK lists; ties are broken by the count across all 20. Found and Passion Digital lead with five each, and eight agencies tie on three, of which ClickSlice, Exposure Ninja and Buried lead the wider count.
Source: Prolinkage count of 10 ranking lists in Google’s UK top 10 for three searches (DataForSEO, pulled 13 November 2026) and 10 further UK lists from web searches the same day. An agency’s own list is excluded from its count.
Blue Array, which tied on three, refused our automated reader on 13 November, so we could not check its pages first-hand. It is worth a look.

Each generative engine optimisation agency, side by side.
All five sell AI search work from a UK base; they differ in packaging and proof.

None of the five publishes AI SEO prices on the pages we read; our guide to what AI search optimisation costs covers typical pricing. If you are comparing US agencies too, see our US list of AI SEO agencies, and for specialists only, our comparison of GEO and AEO agencies.
A test you can run on any agency
“Which UK agencies can help a Manchester engineering firm get recommended in ChatGPT and Google’s AI answers?”
Ask it yourself, then ask each agency why the answer names who it names. A good agency explains the sources behind it.
An invented question for illustration only, not taken from any company’s data.
How Prolinkage works differently.
We start with an audit of your website, carried out without any charge, because we want you to trust our work before you pay for it.
The starting point is an audit of your site, at no charge: where you are named and cited, who appears instead, and what to look at next. It comes back within 24 hours.
One team across the funnel
One team covers SEO built around what you sell, AI search, Google Ads, LinkedIn Ads, GA4, Tag Manager and CRM measurement, CRO and website development. In Google Ads management we set up and check search strategy, landing pages and conversion tracking.
The clients we take
We work mostly with B2B companies, and we work with many companies in the US and UK.
The proof wall: Client 1 to 5
Five anonymised results with sources and dates, names blurred. Each is one business over a stated period, not a promise.
Client 1, a US B2B company (name withheld). Closed-won revenue credited in HubSpot to Organic Search and AI Referrals (original traffic source) rose from $37,350 (Apr–Jun 2026) to $117,100 (Jul–Sep 2026). AI Referrals alone went from $0 to $9,400.
Client 2, a US project-controls consultancy. Website traffic up 120% and top rankings for business keywords, client-reported in a Clutch-verified review (3 Jul 2024), scoring 5.0 on quality, schedule, cost and willingness to refer. Pay-per-click, SEO and social media, Jan 2022–Mar 2024.
Client 3, a Singapore parcel-shipping platform. Organic-search users rose from 330 a month in July 2020 to 5,868 a month in November 2021 (+1,678%), in Universal Analytics.
Client 4, a fitness brand with English and Greek sites. New organic-search users on the English site rose from 265 to 527, 28 Oct–26 Nov 2024 against the previous 30 days, in GA4.
Client 5, a US analytics software company. 2.9K ranking keywords in Semrush’s US desktop database, in the January 2022 snapshot.
Four of the five are classic search results; AI answers lean on pages that already rank. How we read a revenue result, and its limits, is in our article on whether AI visibility drives revenue.

Questions written as UK buyers ask them, run with a UK location.
They know which UK directories, trade bodies and publications AI answers cite in your sector.

Nobody can promise a place in an AI answer; a careful agency says so.
How to judge an agency’s proof
Good proof is dated, names the tool and report it came from, says which engines, prompts and country, and separates AI answers from classic search where it can.
The UK sources and rules are covered in depth in our guide to generative engine optimisation for UK businesses. For first-meeting questions and what good answers sound like, use our questions to ask an SEO or AI search agency. If Google’s AI answers matter most, read what Google documents about AI Overviews; if you sell to businesses, our comparison of US B2B SEO agencies may help too.
Which kind of AI visibility agency fits you.
Answer six questions and the scorer suggests which kind of partner suits you. It points to a type of agency, not a named one, and nothing is sent anywhere.
- B2B, LONG SALESA full-funnel partner that traces AI visibility to CRM revenue

- LOCAL OR MULTI-SITEA local GEO specialist with reviews and location pages
- IN-HOUSE TEAMAn AI search specialist sold in defined pieces

See how AI answers rate your business ↗Questions buyers ask.
What is the best AI SEO agency in the UK?
There is no single answer, because fit depends on what you sell. In the ten UK ranking lists in Google’s top 10 on 13 November 2026, Found and Passion Digital were named most often, followed by ClickSlice, Exposure Ninja and Buried.
What does an AI SEO agency do?
It works to get your business named and cited in AI answers such as ChatGPT, Gemini, Perplexity and Google’s AI Overviews, through a baseline of buyer questions, clearer content, off-site mentions and regular tracking.
Is a GEO agency different from an AI SEO agency?
Mostly in name. A GEO agency, a generative engine optimisation agency, an AI visibility agency and an AI SEO agency describe overlapping work. Ask what is in scope, which engines are tracked and how results are reported.
How do I check an AI visibility agency’s claims?
Ask for dated case studies with the source of each number, and which prompts were tracked, where and how often. Then run a few buyer questions yourself.
Should a UK business hire a UK-based generative engine optimisation agency?
It helps if the agency runs prompts with a UK location and knows the UK sources AI answers cite in your sector. Where the team sits matters less than that.
Where to start.
Pick two or three agencies that match your type, ask each our suggested question, and compare the answers with a dated baseline.
If you would like Prolinkage to be one of those conversations, we start with a look at your site and your buyers’ questions, at no charge. Our page on getting named in ChatGPT and Google’s AI answers sets out the work after that. No pressure either way; the findings are yours to keep.
Start with your audit ↗Sources, read 13 November 2026: 20 UK ranking lists (10 from Google UK’s top 10, via DataForSEO); each agency’s own website; Prolinkage client data as captioned. Agency results are as each agency reports them.
