AI search has changed how buyers find businesses. When someone asks ChatGPT, Perplexity, or Google AI which agency to use - your traditional Google ranking means nothing. What matters is whether an AI decides your business is credible enough to recommend.
Most UK SEO agencies are still optimising for a world that is already changing. A small number have built genuine expertise in AI visibility - getting their clients cited in AI-generated answers, not just ranked on a results page.
This list covers the best of them. We have focused on agencies with a real track record in AI SEO, not ones that have simply added "AI" to their website.
What to Look for in an AI SEO Agency
Before the list, a quick note on what separates genuine AI SEO specialists from agencies that have rebranded their existing services.
Real AI visibility expertise. Can they explain how Perplexity, ChatGPT, and Google AI Overviews each decide what to cite? Do they understand GEO (Generative Engine Optimisation) as a distinct discipline? Or are they just talking about "AI-powered tools" they use internally?
Evidence of results. Can they show you clients whose brands are being cited in AI answers? Do they have a methodology for tracking AI visibility, not just Google rankings?
Content strategy depth. AI visibility is built on content - specifically, content structured to be extracted and cited by AI tools. An agency without a strong content capability cannot deliver AI SEO results.
Honest measurement. AI visibility tracking is still maturing. The best agencies will be transparent about what they can and cannot measure, rather than over-promising with vanity metrics.
The Best AI SEO Agencies in the UK
1. Nalaber
Specialist focus: AI visibility and GEO
Location: Ireland (serving UK clients)
Best for: Businesses that want to be cited by ChatGPT, Perplexity, and Google AI - not just ranked on Google
Nalaber is one of the few agencies in the UK and Ireland built specifically around AI visibility. Founded by Alan Bermingham, the agency focuses entirely on getting clients cited in AI-generated answers - what the industry is calling GEO (Generative Engine Optimisation).
Where most SEO agencies treat AI search as an add-on, Nalaber's entire methodology is built around it. Their free AI visibility analyse tool shows businesses exactly how they currently appear across major AI platforms before any work begins - something very few agencies can offer.
Their approach combines technical SEO foundations with content structured specifically for AI extraction: direct answers, expert authorship, clear definitions, and the kind of consistent brand signals that make AI tools confident enough to cite you.
What makes them different: Nalaber does not take on clients it cannot genuinely move the needle for. They run a diagnostic first, and if AI visibility is not the right priority, they will tell you. That kind of honesty is rare in agency relationships.

2. Found
Specialist focus: Performance marketing and SEO
Location: London
Best for: Mid-to-large businesses wanting integrated SEO and paid media
Found is one of the UK's most established performance marketing agencies, with a strong SEO practice built over more than 15 years. They have been publishing content on AI search topics including Perplexity SEO, Gemini SEO, and AI Overviews, and their team has genuine technical depth.
Their AI SEO offering sits within a broader performance marketing context - useful if you want SEO and paid media managed together, though their AI visibility work is less specialised than a dedicated GEO agency.
Good fit for: Larger businesses that want AI SEO as part of a broader digital marketing engagement.
3. Impression
Specialist focus: SEO, digital PR, and paid media
Location: Nottingham and London
Best for: Businesses wanting strong technical SEO alongside AI visibility work
Impression is a well-regarded UK SEO agency with a strong technical team and a growing focus on how AI is changing search. They have invested in content around E-E-A-T and structured data - two of the foundational elements for AI visibility - and their digital PR capability supports the off-site authority building that AI citations require.
Good fit for: Businesses with complex technical SEO challenges who also want to start building AI visibility.
4. Evolved Search
Specialist focus: SEO and content strategy
Location: Newcastle
Best for: Businesses that want a content-led approach to search visibility
Evolved Search has built a strong reputation for content-driven SEO. Given that AI visibility is fundamentally a content discipline - structured, authoritative, extractable content - agencies with deep content expertise have a natural advantage in this space.
Good fit for: Content-heavy businesses, publishers, and brands with strong editorial output that needs to be structured for AI citation.
5. Rise at Seven
Specialist focus: Creative SEO and digital PR
Location: Sheffield, London, and Manchester
Best for: Brands that want high-profile coverage driving both AI citations and traditional backlinks
Rise at Seven combines creative content campaigns with technical SEO and digital PR. Getting your brand mentioned in high-authority publications - which their campaigns are designed to do - is one of the most effective ways to build the off-site authority signals that AI tools look for.
Good fit for: Consumer and lifestyle brands wanting AI visibility built through earned media and brand awareness.
How to Choose the Right AI SEO Agency
The right agency depends on your specific situation. Here are the most important questions to ask before signing with anyone.
Can they show you AI citations they have earned for clients? Not rankings, not traffic - actual citations in ChatGPT, Perplexity, or Google AI answers. This is the deliverable. If they cannot show you it, they have not done it.
Do they have a methodology for tracking AI visibility? Google Search Console does not tell you whether AI tools are citing you. Ask how they measure this. If they do not have an answer, they are not genuinely doing AI SEO.
Do they understand each platform differently? ChatGPT uses Bing's index. Perplexity indexes in real time. Google AI Overviews draw from Google's rankings. Gemini uses Google's full ecosystem. An agency that treats all AI platforms the same does not understand the space.
What does their content process look like? AI visibility is built on content. Ask to see examples of content they have produced that is structured for AI extraction - not just well-written articles, but content with direct answers, clear definitions, expert attribution, and summary sections.
Are they honest about what they cannot measure? AI visibility tracking is still developing. Any agency that promises specific AI citation rates or guaranteed results is overselling. Look for honesty about what can and cannot be measured today.
The Bottom Line
AI search is not coming. It is here. Businesses that invest in AI visibility now will compound that advantage over the next two to three years. Businesses that wait will spend that time catching up.
The agencies on this list are the ones we believe are genuinely equipped to help. If you want to understand your specific situation before choosing an agency, Nalaber's free AI visibility analyse tool gives you a clear picture of where you currently stand across ChatGPT, Perplexity, and Google AI - in about two minutes.

FAQ
What is an AI SEO agency?
An AI SEO agency specialises in getting businesses cited in AI-generated answers from tools like ChatGPT, Perplexity, Google AI Overviews, and Gemini. This is distinct from traditional SEO, which focuses on ranking on Google's results page.
Is AI SEO the same as GEO?
GEO (Generative Engine Optimisation) is the technical term for AI SEO - optimising to appear in AI-generated answers rather than traditional search results. The terms are used interchangeably.
How much does AI SEO cost in the UK?
AI SEO retainers from specialist agencies typically range from £1,500 to £5,000+ per month depending on scope, competition, and the number of AI platforms being targeted. As with traditional SEO, the most meaningful variable is not monthly cost but cost per result.
How long does AI SEO take to work?
Most businesses start seeing meaningful AI citation improvements within three to six months of focused work. The timeline depends on starting domain authority, content quality, and how competitive your sector is in AI search.
Can I do AI SEO without an agency?
Some elements - improving content structure, adding summary sections, ensuring Bing indexing - can be done in-house. For a systematic, sustained programme across multiple AI platforms, most businesses find specialist support delivers faster and more consistent results.
