In the last two years, AI search has gone from a novelty to a genuine buying channel. ChatGPT alone now has over 883 million monthly users, and AI chatbots collectively handle billions of queries a month, a huge share of which are people researching products and vendors before they ever open Google.
Brands are also seeing what’s at stake: citation overlap between traditional top-10 rankings and what AI Overviews actually cites has collapsed from around 76% to as low as one in six in some categories, meaning ranking well on Google no longer guarantees you show up when a buyer asks an AI system the same question.
That gap is why UK brands are now pouring budget into AI SEO specifically, not just traditional SEO with extra reporting bolted on.
But with the discipline only around two years old, it’s hard to tell brands that actually understand AI search from ones simply slapping an “AI SEO specialist” badge on their existing services.
This guide covers the 7 best AI SEO agencies in UK, based on their ratings, client reviews, services, specialisations and actual client evidence.
- TL;DR: Best AI SEO Agencies in UK
- Found – best for enterprise brands that want AI search folded into a full-service growth strategy.
- ClickSlice – best for ecommerce and SaaS businesses wanting GEO connected to existing SEO.
- Qoulomb – best for B2B enterprise and mid-market companies with long sales cycles that want AI citations tied to pipeline and revenue.
- Hallam – best for B2B and larger organisations wanting integrated marketing plus AI search .
- Blue Array – best for SEO-led organisations extending into GEO and digital PR.
- Screaming Frog – best for technically complex sites where crawlability may be limiting AI visibility.
- Impression – best for performance-led brands wanting GEO tied to SEO, PR and authority.
- Most UK AI SEO retainers range from £100/month for basic monitoring tools to £5,000+/month for full-service GEO programmes. B2B-specific GEO retainers, like Qoulomb's, typically run £2,000 to £10,000/month.
What We Looked At
Ranking AI SEO and GEO agencies is harder than ranking traditional SEO firms because the category is still new and there is no single industry benchmark. To keep this list useful, each agency below was reviewed against the same criteria:
- AI visibility and GEO expertise, not just traditional SEO with an “AI” label added
- Platform coverage across ChatGPT, Perplexity, Google AI Overviews, Gemini and Copilot
- Technical SEO foundation, since crawlability and structure still affect what AI systems can retrieve and cite
- Reporting and measurement, including whether visibility is tied to pipeline or just impressions
- Client evidence, including case studies, testimonials and reported results
- Sector fit, since a B2B enterprise brand and a local ecommerce store need very different approaches
This list also includes agencies that serve UK businesses and UK search intent without necessarily being headquartered in the UK. As AI search flattens geography, B2B buyers increasingly hire the specialist agency that fits their sales motion and budget, wherever that agency is based, so this guide reflects that reality rather than restricting the list to UK postcodes alone.

The 7 Best AI SEO Agencies in UK
1. Found
Found is a London-based digital agency offering AI SEO and GEO as part of a broader performance marketing service, built on its proprietary Luminr technology. Its approach combines technical optimisation, content strategy and off-site authority building, which matters because AI systems rarely rely on a single page or signal when generating an answer.
Found suits larger organisations that want AI search handled alongside SEO, paid media and analytics rather than as a standalone project. Buyers should confirm how much of the team’s day-to-day work is dedicated specifically to GEO, since it sits within a wider service list.
Key services:
- GEO and AI SEO powered by proprietary Luminr technology
- Technical optimisation and site structure work
- Content strategy and off-site authority building
- Search strategy, measurement and reporting
Best for: Enterprise and larger organisations that want AI search inside a full-service growth strategy.
2. Qoulomb
Qoulomb is a B2B-focused SEO and GEO agency working with companies ranging from venture-funded startups to Fortune 500 enterprises, across 13+ industries including AI and tech, SaaS, fintech, healthtech, legaltech, edtech and B2B manufacturing. The agency has worked with 200+ B2B clients, including Samsung, Zetwerk, Slice, Cybertech and GAIN Servicing, and holds a 4.9-star Clutch rating.
What separates Qoulomb from most agencies on this list is that it runs GEO and SEO as one integrated system rather than two disconnected teams working from separate playbooks. Every AI citation is tracked back to pipeline and closed revenue rather than reported as a standalone visibility metric, with coverage spanning 12+ AI surfaces including ChatGPT, Perplexity, Google AI Overviews, Microsoft Copilot and Gemini.
Qoulomb works exclusively with B2B companies that have long, complex sales cycles, not short-cycle B2C or ecommerce brands, and average client retention runs 2.5 to 4 years, well above the 6 to 12 month norm for typical agency engagements. This makes it a relevant option for UK B2B companies whose buyers are increasingly using AI tools to research and shortlist vendors, even though the agency itself operates from Indore and Bengaluru rather than a UK office.
Key services:
- GEO and AEO run as one integrated system with SEO, not separate workstreams
- AI citation tracking across 12+ surfaces including ChatGPT, Perplexity, Google AI Overviews, Copilot and Gemini
- Reporting tied to pipeline, MQLs, SQLs and closed revenue, not just visibility metrics
- Content marketing, case studies and thought leadership built for B2B buying committees
Best for: B2B enterprise, mid-market and Fortune 500 companies with long sales cycles that want AI citation visibility tied directly to pipeline and revenue, not early-stage startups or B2C brands.
Budget: £2,000 to £10,000 per month for SEO and GEO retainers.

Key services:
- AI search strategy and GEO
- Topical authority building and technical audits
- Competitor analysis and earned web mentions

Blue Array is a UK organic search agency offering SEO, GEO and digital PR, with GEO work focused on visibility across ChatGPT, Gemini and Llama.

Key services:
- GEO, SEO and digital PR
- Organic search strategy and technical SEO
- AI visibility reporting
- Content recommendations
Best for: Organisations that already invest in organic search and want GEO built on top of that existing programme.

This agency is worth shortlisting specifically when the underlying website, not the content strategy, may be the reason AI systems are struggling to crawl, index or cite a brand.
Key services:
- AI search optimisation across ChatGPT, Gemini, AI Mode and Perplexity
- Commercial prompt tracking
- AI bot analysis and referral attribution
- Technical SEO audits
Best for: Larger or technically complex websites where crawlability and indexation may be limiting AI visibility.
7. Impression
Impression runs a dedicated GEO service built around earning mentions and citations across ChatGPT, Perplexity and Google Gemini, connected to its wider SEO, digital PR and authority-building work.
It tends to suit larger marketing teams that want AI search visibility to support a broader acquisition strategy rather than operate as an isolated workstream.
Key services:
- Dedicated GEO service for ChatGPT, Perplexity and Gemini
- SEO and digital PR
- Authority and citation building
- Performance marketing integration
Best for: Performance-led brands that want GEO integrated with SEO, PR and authority building.
Quick Comparison: Top AI SEO Agencies in UK
How to Choose the Right AI SEO Agency for UK Search Visibility
Before signing a retainer, ask each shortlisted agency:
Which AI platforms do they actually track?
ChatGPT, Perplexity, Google AI Overviews, Gemini and Copilot behave differently, so an agency checking only one or two is giving you a partial picture.
How do they separate mentions from citations?
Being mentioned in passing is not the same as being cited as a trusted source, and the difference matters for how much a brand can influence AI-generated recommendations.
Does reporting stop at visibility metrics, or connect to pipeline and revenue?
Citation counts are a useful diagnostic, but for most B2B and enterprise buyers the real question is whether AI visibility is translating into qualified leads and closed deals.
Do they promise guaranteed rankings or fixed AI mentions?
No credible agency can, since AI-generated answers vary by prompt, platform, timing and context. Be cautious of anyone who says otherwise.
What is their sector experience?
A university, ecommerce brand, SaaS company and B2B manufacturer all need different AI Visibility strategies because their audiences ask different questions.
Final Thoughts
AI search visibility is no longer optional for UK businesses whose buyers research vendors through ChatGPT, Perplexity and Google AI Overviews before ever visiting a website.
The right agency depends on what you need most: a full-service partner like Found that folds AI search into a wider growth strategy, a technical specialist like Screaming Frog that fixes the foundations AI systems rely on, or a focused GEO partner like Qoulomb that ties every citation back to pipeline and revenue.
Use the comparison above as a starting point, then request a visibility audit from two or three shortlisted agencies before committing to a retainer.
Frequently Asked Questions (FAQs)
What is the best AI SEO agency in the UK?
There is no single best AI SEO agency in the UK for every business. The right choice depends on your sector, sales cycle and budget. Found and Hallam suit larger organisations wanting AI search inside a full-service strategy, Rank4AI suits businesses wanting an AI-only specialist, and Qoulomb suits B2B enterprise and mid-market companies that want AI citation visibility tied directly to pipeline and revenue.
What is the difference between an AI SEO agency and a traditional SEO agency?
A traditional SEO agency focuses on rankings, clicks and organic traffic within search engines like Google. An AI SEO or GEO agency focuses on whether a brand appears inside AI-generated answers, how it is described, whether it is cited as a source, and how it compares with competitors across AI-led platforms like ChatGPT and Perplexity. The two overlap around technical SEO and content quality, but the measurement and objectives differ.
Is GEO the same as AEO?
GEO, or Generative Engine Optimisation, and AEO, or Answer Engine Optimisation, are closely related and often used interchangeably. Both describe the practice of improving how a brand appears in AI-generated answers rather than traditional search rankings. Some agencies use one term consistently, while others treat GEO as the broader discipline and AEO as the practice of optimising for direct answer formats.
Can an AI SEO agency guarantee ChatGPT or Perplexity mentions?
No credible agency can guarantee specific AI mentions. AI-generated answers change based on the prompt, platform, timing and available sources at the time of the query. A trustworthy agency improves the underlying signals, content structure and citation-worthiness that make a brand easier for AI systems to retrieve, trust and recommend, rather than promising fixed placements.
How much does an AI SEO or GEO agency cost in the UK?
Pricing varies widely by scope. Smaller AI visibility monitoring tools start from around £100 to £800 per month, full-service AI SEO and GEO agencies typically range from £1,500 to £5,000 per month, and specialist B2B GEO retainers such as Qoulomb’s run from £2,000 to £10,000 per month depending on the level of implementation and reporting required.
Yes, keywords still matter, but understanding what people want and covering topics fully matters even more now. AI SEO optimization focuses on fully answering questions instead of just matching exact keyword phrases, which makes deeper content more valuable.
