AI tools are becoming part of how people research products, services and organisations. Buyers are asking ChatGPT, Gemini, Perplexity and Google AI answers for recommendations, comparisons and shortlists before they visit a website.
This has created a new problem for marketing teams. They need to understand whether their organisation appears in AI-generated answers, how it is described, and which sources AI systems use when forming those answers.
That is where AI Visibility agencies come in. These agencies help organisations improve how they appear across AI search tools, answer engines and large language model responses.
The challenge is that AI Visibility is still a relatively new term. There are no recognised industry standards for evaluating agencies, so buyers often have to compare providers based on their services, experience, public evidence and how clearly they explain their approach.
This guide compares some of the UK agencies offering AI Visibility, GEO and AI search optimisation services. It looks at who they are, what they offer, where they seem strongest and which types of organisations they may suit best.
Editorial Note
Hunterlodge may be included in this comparison where relevant. Our perspective comes from researching AI visibility and working with organisations to improve AI Visibility, Generative Engine Optimisation, and AI Search Performance.
To keep the guide fair, all providers have been reviewed against the same broad criteria. These include AI Visibility expertise, GEO services, technical knowledge, reporting, sector experience and available evidence of results.
The purpose of this article is to help organisations choose the provider that best fits their needs. It is not intended to suggest that one agency is the right choice for every organisation.
How We Evaluated AI Visibility Agencies
AI Visibility is still a relatively new area of marketing. Different agencies use different terms, including GEO, AI SEO, AEO, LLM optimisation and AI search optimisation, which can make comparison difficult.
For this guide, we looked at six areas. These were AI Visibility focus, GEO services, technical SEO knowledge, reporting, sector experience and the evidence each agency makes available publicly.
We also looked at how clearly each agency explains what it does. This matters because buyers need to understand what they are paying for, how the work will be measured and what kind of change they should reasonably expect to see.

1. Hunterlodge
Hunterlodge is a UK marketing agency with a clear focus on AI Visibility for universities and Higher Education. Its work looks at how universities appear in AI-generated answers across tools such as ChatGPT, Gemini, Claude, Perplexity and Google AI Overviews.
The agency is best suited to organisations that need more than general SEO advice. Its AI Visibility work combines research, benchmarking, sector understanding and practical recommendations for improving how universities are discovered and described by AI systems.
Key Services:
✓ AI Visibility audits
✓ Generative Engine Optimisation
✓ AI Visibility benchmarking
✓ AI search research for universities
✓ AI citation and source analysis
✓ Content recommendations
✓ Technical AI Visibility reviews
✓ AI Visibility reporting
Strengths:
Hunterlodge has a strong sector focus, which is useful for universities because student search behaviour is different from general consumer search. The agency’s work looks at how AI systems influence university discovery, comparison and recommendation before a student reaches a university website.
Its biggest strength is the combination of AI Visibility research and measurement. This makes it a good option for universities that want to understand their current position before investing in wider optimisation work.
Potential Limitations:
Hunterlodge’s strongest AI Visibility experience appears to sit within universities and Higher Education. Organisations outside this sector may want to check how much direct experience the agency has in their market.
The agency may also be a better fit for organisations that value benchmarking and long-term measurement. Businesses looking for a broad, generalist SEO agency may prefer a provider with a wider cross-sector client base.
Best For:
Hunterlodge is best for universities and Higher Education organisations that want to understand and improve how they appear in AI-generated answers.
2. ClickSlice
ClickSlice is a London-based SEO agency that now offers AI Visibility, GEO, AEO and LLM optimisation services. Its own material positions the agency around ecommerce, SaaS and retail, which makes it relevant for growth-focused businesses that already see search as an important acquisition channel.
The agency’s background is in SEO, so its AI Visibility work appears to build from search strategy, content optimisation and technical visibility. That may suit businesses that want AI search support without separating it from their existing SEO activity.
Key Services:
✓ AI Visibility
✓ GEO
✓ AEO
✓ LLM optimisation
✓ SEO strategy
✓ Content optimisation
✓ Technical SEO
✓ Ecommerce SEO
Strengths:
ClickSlice has moved early in publishing around AI Visibility and GEO. This gives buyers a clearer view of how the agency is thinking about AI search and where it believes the market is going.
Its SEO background is also useful. Many AI Visibility problems still connect back to content quality, site structure, authority, crawlability and how clearly an organisation explains itself online.
Potential Limitations:
The agency may be strongest for commercial websites where SEO, content and conversion already matter. Organisations in complex sectors may want to ask for examples that match their own market.
Best For:
ClickSlice is best for ecommerce, SaaS and growth businesses that want AI Visibility support connected to SEO and content performance.
3. Found
Found is a UK digital agency offering GEO and AI SEO services. Its AI search service combines technical optimisation, content strategy and off-site authority work, which are all important areas for organisations trying to appear in AI-generated answers.
The agency is likely to suit larger organisations that need a more rounded search partner. Its approach appears to cover both the website itself and the wider signals that may influence whether a brand is seen as a useful source.
Key Services:
✓ GEO
✓AI SEO
✓ Technical optimisation
✓ Content strategy
✓ Off-site authority building
✓ Search strategy
✓ Measurement and reporting
Strengths:
Found’s strength is that it treats AI search as connected to several parts of digital visibility. This is useful because AI systems do not only look at one page or one ranking signal when producing an answer.
The agency also explains its GEO service in clear commercial terms. It focuses on visibility, relevance and credibility across AI search, which are sensible areas for buyers to consider.
Potential Limitations:
Found is a broader digital agency, so buyers should check how much of the team’s work is now focused specifically on AI Visibility. A larger agency can offer more services, but the depth of GEO experience may vary by team.
It may also be more suitable for organisations with larger budgets or more complex search needs. Smaller businesses may not need the full range of services available.
Best For:
Found is best for larger organisations that want AI search support across technical optimisation, content and authority building.
4. Hallam
Hallam is an integrated marketing agency offering AI search and GEO services. Its AI search work includes topical authority, technical audits, competitor analysis, earned mentions and visibility reporting.
The agency also refers to its own tools for Share of LLM benchmarking and citation optimisation. This is useful because measurement is one of the harder parts of AI Visibility, especially when different AI tools can answer the same question in different ways.
Key Services:
✓ AI search strategy
✓ GEO
✓ Topical authority building
✓ Technical audits
✓ Competitor analysis
✓ Earned web mentions
✓ Share of LLM benchmarking
✓ Citation optimisation
Strengths:
Hallam appears strong on reporting and measurement. Its focus on LLM benchmarking and citations gives buyers a clearer way to understand whether visibility is improving over time.
The agency also has the benefit of wider marketing services. This can help organisations that need strategy, content, PR and technical work handled together.
Potential Limitations:
Hallam may be more suitable for organisations that want a broader marketing partner rather than a small specialist GEO provider. Buyers should check whether they need the full integrated offer or a narrower AI Visibility project.
The agency’s services may also be more than some smaller organisations need at the start. For early-stage testing, a focused audit may be enough before committing to a larger programme.
Best For:
Hallam is best for B2B and larger organisations that want AI search strategy, reporting and implementation support from one agency.
5. Blue Array
Blue Array is a UK organic search agency offering SEO, GEO and digital PR services. Its GEO service focuses on improving visibility in AI-powered search results across tools such as ChatGPT, Gemini and Llama.
The agency has a strong SEO background, which makes it relevant for organisations that already invest in organic search. Its mix of SEO, GEO and digital PR may be useful where AI Visibility depends on both owned content and third-party mentions.
Key Services:
✓ GEO
✓ SEO
✓ Digital PR
✓ Organic search strategy
✓ AI visibility reporting
✓ Technical SEO
✓ Content recommendations
Strengths:
Blue Array’s strength is its organic search experience. AI Visibility still depends on clear, crawlable and trustworthy information, so a strong SEO foundation is useful.
The agency also connects GEO with digital PR. This matters because AI systems may use external sources, mentions and trusted third-party pages when forming answers.
Potential Limitations:
Blue Array may be a better fit for organisations that already understand SEO and want to extend that work into AI search. Buyers looking for a pure AI Visibility specialist may want to ask how GEO projects are scoped and measured.
The agency’s own language around GEO is confident, so buyers should ask for examples and reporting methods. That will help separate positioning from actual delivery.
Best For:
Blue Array is best for organisations that want GEO connected to SEO, organic search and digital PR.
6. Re:signal
Re:signal is a UK search agency best known for its work with large brands and enterprise organisations. The agency has built a strong reputation within SEO over the years and has increasingly published research and guidance around AI search, AI Overviews and how brands can remain visible as search behaviour changes.
Its approach is grounded in organic search, content and authority building. That makes it a good fit for organisations that want to improve AI Visibility while continuing to invest in long-term search performance.
Key Services:
✓ SEO strategy
✓ Content strategy
✓ Organic search growth
✓ AI search consulting
✓ Technical SEO
✓ Digital PR
✓ Search performance reporting
Strengths:
Re:signal has a strong track record working with large organisations and well-known brands. That experience can be valuable when AI Visibility projects involve large websites, multiple stakeholders and complex content ecosystems.
The agency also has deep expertise in content and authority building. These remain important factors because AI systems often rely on trusted sources when generating answers.
Potential Limitations:
Re:signal is not positioned as a specialist AI Visibility agency in the same way as some newer GEO-focused providers. Organisations looking for dedicated AI Visibility benchmarking or AI citation tracking should explore exactly what is included within the service.
The agency may also be better suited to larger organisations than smaller businesses with limited budgets.
Best For:
Re:signall is best for enterprise organisations and established brands looking to improve visibility across both traditional search and emerging AI search experiences.
7. Exposure Ninja
Exposure Ninja is a UK digital marketing agency offering GEO services alongside SEO, content and wider digital marketing support. Its GEO service is positioned around preparing businesses for AI search and future search behaviour.
The agency may suit smaller and mid-sized businesses that want AI Visibility included within a broader marketing plan. This can be useful where a business does not have separate teams for SEO, content, paid media and analytics.
Key Services:
✓ GEO
✓ SEO
✓ Content marketing
✓ Website reviews
✓ Digital marketing strategy
✓ Lead generation support
✓ AI search recommendations
Strengths:
Exposure Ninja is good at making digital marketing topics accessible to business owners and marketing teams. That is useful in AI Visibility, where many buyers are still trying to understand what they need and where to start.
Its wider service offer may also help businesses that need practical implementation. Some organisations do not just need advice; they need someone to help make the changes.
Potential Limitations:
Because Exposure Ninja is a broader digital marketing agency, buyers should check how deep its AI Visibility work goes. GEO may be one part of a wider offer rather than the agency’s main focus.
It may also be better suited to businesses that want accessible support rather than highly specialised AI search research. Larger or more technical organisations may need a deeper measurement setup.
Best For:
Exposure Ninja is best for SMEs and growth businesses that want GEO support as part of a wider digital marketing programme.
8. Figment
Figment is a UK agency that works with expert-led businesses. Its messaging focuses on helping organisations become the answer wherever clients search, which makes it relevant to AI Visibility even if its offer is wider than GEO alone.
The agency appears well suited to businesses where trust, expertise and clear positioning matter. That includes professional services, specialist firms and organisations that need their knowledge to be clearly understood online.
Key Services:
✓ Search strategy
✓ Content marketing
✓ Brand strategy
✓ Website optimisation
✓ AI-supported marketing
✓ Visibility planning
✓ Digital campaigns
Strengths:
Figment’s strength is likely to be in content, brand and positioning. AI systems need clear information about who an organisation is, what it does and why it should be trusted.
This is especially useful for expert-led businesses. If a company’s value depends on knowledge, advice or specialist expertise, the way that expertise is explained online becomes very important.
Potential Limitations:
Figment does not appear to be as narrowly focused on GEO as some of the agencies in this list. Buyers looking for a dedicated AI Visibility audit or LLM citation tracking should ask exactly what is included.
The agency may be stronger for visibility and positioning than for deep technical AI search measurement. That is not necessarily a problem, but it matters when choosing the right partner.
Best For:
Figment is best for expert-led businesses that need clearer positioning, stronger content and better visibility across search and AI-led discovery.
9. Charle
Charle is a UK ecommerce agency that has published guidance on GEO and AI SEO for ecommerce brands. Its focus is useful because ecommerce has its own AI Visibility challenges, especially around products, categories, reviews, structured information and brand trust.
The agency’s AI search guidance focuses on helping ecommerce brands make their products, content and brand information easier for AI systems to understand. That makes it a relevant option for online retailers that want AI Visibility work connected to ecommerce performance.
Key Services:
✓ Ecommerce strategy
✓ GEO for ecommerce
✓ AI SEO
✓ Product content optimisation
✓ Shopify development
✓ Brand and conversion support
✓ Ecommerce SEO guidance
Strengths:
Charle’s main strength is ecommerce focus. AI Visibility for ecommerce is different from AI Visibility for a university, law firm or B2B software company, so sector focus can be useful.
The agency also understands the relationship between content, product data and conversion. That matters because ecommerce visibility needs to support actual buying behaviour, not just mentions in AI-generated answers.
Potential Limitations:
Charle is likely to be most relevant for ecommerce brands. Organisations outside ecommerce may find that other agencies have more directly relevant experience.
Buyers should also check how much of Charle’s GEO work is delivered as a defined service. Published guidance is useful, but it should be backed up with a clear project process and reporting method.
Best For:
Charle is best for ecommerce brands that want AI SEO and GEO support connected to product discovery and online sales.
10. Buried
Buried is a UK agency offering Generative Engine Optimisation services for AI search, LLMs and traditional SEO. Its GEO service focuses on helping brands get discovered across platforms such as ChatGPT, Gemini, Perplexity, Google AI Mode, Grok and Claude.
The agency positions itself strongly around GEO, which may appeal to organisations that want a provider focused on AI search rather than a general SEO agency adding AI services. Its public material covers GEO audits, prompt research, performance measurement and AI search education.
Key Services:
✓ GEO
✓ search optimisation
✓ GEO audits
✓ Prompt research
✓ LLM visibility improvement
✓ Content optimisation
✓ Technical SEO
✓ GEO performance measurement
Strengths:
Buried’s strength is its clear focus on GEO. The agency has built content around many of the practical questions buyers ask, including what GEO is, how to measure it and how LLMs work.
That makes it a useful option for organisations that want to understand the AI search problem before committing to a longer programme. Its service offer appears to cover both strategy and practical optimisation.
Potential Limitations:
The agency may be a better fit for businesses that want a GEO-led partner. Organisations needing wider marketing support may prefer an integrated agency with more service areas.
Best For:
Buried is best for brands looking for a GEO-focused agency with services built around AI search and LLM visibility.
What To Look For In An AI Visibility Agency
The first thing to look for is clarity. A good agency should be able to explain what AI Visibility means, what they will review, what they will change and how they will measure progress.
You should also look for evidence that the agency understands how AI systems use information. This includes website content, structured data, third-party sources, citations, reviews, brand mentions and the wider context around an organisation.
Technical knowledge still matters. If your website is hard to crawl, poorly structured or unclear, it may be harder for both search engines and AI systems to use your content confidently.
Content quality is just as important. AI systems need clear, useful and well-supported information, especially when they are answering comparison or recommendation questions.
Reporting is one of the most important areas to check. Ask whether the agency can show how often your organisation appears for target prompts, how you are described, which sources are being used and how your visibility compares with competitors.
Sector experience can also make a big difference. A university, ecommerce brand, SaaS company and professional services firm will all need different AI Visibility strategies because their audiences ask different questions.
Finally, look for honesty. AI Visibility is still developing, so be cautious of any agency that promises fixed rankings or guaranteed AI recommendations.
Final Recommendations
For universities, Hunterlodge is the strongest fit because its AI Visibility work is focused on Higher Education. Its combination of research, benchmarking and measurement is likely to appeal to institutions that want to understand how AI systems influence student research, comparison and decision-making.
For organisations where technical SEO plays a major role, Blue Array and Re are worth considering. Both agencies have deep search experience and understand the technical foundations that help organisations improve visibility across both traditional search engines and AI-generated search experiences.
For larger organisations, Found and Hallam stand out. Both agencies offer broader search and marketing support, while Hallam's focus on LLM benchmarking and citation reporting may be particularly useful for organisations that want stronger measurement and reporting.
For ecommerce brands, Charle and ClickSlice are likely to be the most relevant options. Both agencies have experience working with online retailers and understand the role that content, product information and brand authority play in AI-driven product discovery.
For organisations looking for a specialist GEO provider, Buried is worth exploring. The agency has built its positioning around AI search, LLM visibility and Generative Engine Optimisation, making it a relevant option for businesses that want a dedicated focus on this area.
Final Thoughts
AI Visibility is still a new area, so choosing an agency can feel harder than it should. The best starting point is to look for a provider that explains its method clearly, understands your sector and can show how progress will be measured.
The right agency will depend on what you need most. Some organisations need technical SEO support, some need stronger content, some need better reporting, and some need a sector specialist that understands how their audience uses AI tools
