10 GEO Agencies to Consider for AI Search

AI search is changing the way people discover, compare, and evaluate brands. Instead of relying exclusively on traditional search results, users can now ask ChatGPT, Google AI experiences, Gemini, Perplexity, and other AI-powered systems to recommend companies, explain products, compare providers, or identify the best solution for a particular need. 

That shift has created a growing need for Generative Engine Optimisation (GEO), Answer Engine Optimisation (AEO), and broader AI Search strategies. 

However, choosing an agency is not simply a matter of finding one that uses the term “GEO.” Different agencies approach AI Search from different angles. Some have deep technical SEO expertise, while others focus heavily on content, digital PR, authority, enterprise search, measurement, or AI-specific optimisation. 

The following list is not a numerical ranking. The agencies are included for comparison, and the right choice depends on an organisation’s size, market, existing search infrastructure, competitive environment and specific AI Search requirements. 

What Should You Look for in a GEO Agency? 

A strong AI Search programme usually requires more than rewriting website content. 

Depending on the organisation, an agency may need to address technical SEO and crawlability, entity understanding, structured data, content architecture, authority and third-party mentions, competitive analysis, AI visibility measurement, and international search requirements. 

For established and enterprise brands, another important consideration is whether the agency can integrate AI Search into an existing SEO, content, PR, digital marketing, and analytics operation rather than treating GEO as an isolated campaign. 

With that in mind, here are 10 agencies worth considering. 

1. iPullRank

iPullRank is particularly interesting for organisations looking for a technically sophisticated approach to AI Search. 

Its work around Relevance Engineering focuses on how information retrieval, semantic relationships, content structures, and AI systems interact. The agency’s AI Search offering covers strategy, content, technical optimisation, and measurement, while its AI Search Manual provides a detailed framework for understanding GEO and modern retrieval systems. 

This makes iPullRank a strong candidate for established brands with technically complex websites or large content ecosystems. 

Its approach is especially relevant when the challenge goes beyond producing more content and involves understanding why particular information is retrieved, extracted, or selected by AI systems. 

Best suited to: Enterprise and technically complex organisations that want a strong combination of technical SEO, information retrieval, AI Search strategy, and measurement. 

2. Blue Array

Blue Array brings an established organic search background to GEO and AI Search. 

Its GEO services cover content discoverability, technical optimisation, AI visibility monitoring, citation and mention analysis, and competitor benchmarking. The agency has also published research examining how brands appear across AI platforms, including research into the visibility of property brands. 

One of Blue Array’s strengths is the connection between traditional SEO and newer AI Search requirements. Rather than treating GEO as completely separate from search optimisation, the agency positions it within a broader organic search strategy. 

That can be particularly valuable for established businesses that already have a significant SEO programme and want to extend visibility into AI-powered search. 

Best suited to: Established and enterprise brands looking to integrate GEO with a mature SEO and organic search programme, particularly in the UK and European markets. 

3. Netsleek

Netsleek takes a more specialised approach, positioning itself as an AI Search & Brand Discoverability agency focused on GEO, AEO, AI visibility, entity optimisation, AI-ready content engineering, and technical search. 

Its approach also places strong emphasis on measurement, distinguishing between mentions, citations and recommendations and examining the prompts, systems, competitors and evidence behind headline AI visibility scores. 

Its methodology is built around the idea that AI Search is not simply traditional SEO with a new interface. The company separates the different layers involved in AI visibility, including retrieval, entity understanding, content interpretation, trust, inclusion, and recommendation. 

Netsleek’s published frameworks include its AI Visibility Framework, Entity–First Optimisation, Knowledge Graph Engineering, AI Content Engineering, and AI Selection and Recommendation Framework. The company describes these frameworks as a connected methodology for understanding how AI systems interpret, evaluate, and select brands. 

This makes Netsleek particularly relevant for organisations that want AI Search to be treated as a dedicated strategic discipline rather than simply an extension of conventional SEO. 

Its positioning is global and remote-first, with services aimed at organisations across the UK, Europe, North America, and other international markets. 

Best suited to: Mid-market and enterprise organisations looking for a specialist AI Search partner with an emphasis on GEO, entity optimisation, AI visibility measurement, and AI-ready content and technical infrastructure. 

4. First Page Sage

First Page Sage has been publishing research into GEO and AI Search for several years, making research and methodology an important part of its positioning. 

Its current AI Search work examines how generative AI systems recommend companies and products, including factors such as authoritative list mentions and the role of online content in AI recommendations. The agency has also published research and frameworks around agentic search optimisation. 

For organisations interested in the relationship between content strategy, authority, and AI recommendations, this research-led approach can be particularly relevant. 

Best suited to: Established organisations that value research-driven SEO and GEO strategies, particularly those looking to connect AI visibility with content and authority building. 

5. Impression

Impression approaches AI Search as part of the broader evolution of organic search. 

Its GEO work focuses on helping content become interpretable and trustworthy enough for AI systems to use as sources, with particular attention to content clarity, question-and-answer formats, structured information, brand citations, and authority. 

The agency also connects GEO with digital PR and brand activity. This is important because AI visibility is not determined entirely by what exists on a company’s own website. Third-party sources, brand mentions, and broader online authority can influence how a company is represented across AI-generated answers. 

Best suited to: Established and larger brands seeking an integrated SEO, GEO, content, and digital PR strategy. 

6. NoGood

NoGood approaches AI Search from a broader growth-marketing perspective. 

Its AEO offering covers visibility across ChatGPT, Gemini, Perplexity, and Google AI experiences, while the agency also combines SEO, content, digital PR, analytics, CRO, paid media, social, and other growth disciplines. 

This breadth can be useful for brands that do not want AI Search to operate in isolation from acquisition and conversion activity. 

NoGood is also particularly relevant to organisations in sectors such as SaaS, B2B, healthcare, fintech, consumer, and AI, where content, authority, and category positioning can play an important role in the buyer journey. 

Best suited to: Growth-focused brands that want AI Search combined with a wider performance and growth-marketing programme. 

7. Directive

Directive is particularly focused on B2B growth and has incorporated GEO into its approach to modern search. 

Its positioning centres on helping B2B organisations become discoverable during the research and comparison stages of the buying journey. That is increasingly relevant to AI Search, where buyers may ask an AI system to compare software platforms, technology providers, or business services before speaking with a salesperson. 

Directive combines search, content, communications, paid media, creative, and revenue operations within its wider B2B growth model. 

Best suited to: B2B organisations, particularly technology and enterprise companies, where AI Search visibility needs to connect directly with demand generation and qualified pipeline. 

8. DEPT

DEPT® takes a broad digital transformation approach to GEO and search. 

Its GEO offering connects traditional SEO with AI-powered discovery, technical foundations, structured data, social search, and other digital channels. The agency specifically discusses visibility across Google AI experiences, ChatGPT, Perplexity, and Claude. 

This broader perspective can be useful for international brands that need search visibility to work across multiple digital touchpoints rather than within SEO alone. 

DEPT® is therefore less about a narrowly defined GEO-only service and more about integrating AI Search into a wider digital ecosystem. 

Best suited to: Large, international, and digitally mature organisations looking for AI Search to sit within a broader digital transformation and marketing programme. 

9. Peak Ace

Berlin-based Peak Ace has expanded its international SEO offering into LLMO and GEO, alongside technical SEO, content, digital PR, analytics, paid media, and other digital disciplines. 

Its international orientation is an important consideration for multinational companies. Peak Ace works across multiple languages and markets, making it potentially well suited to organisations where AI Search visibility needs to be considered across different countries and language environments. 

Its broader SEO and digital expertise also provides a useful foundation for organisations that want GEO to build on an existing international search programme. 

Best suited to: International and multilingual organisations that need GEO integrated with technical SEO, content, digital PR, and multi-market search strategy. 

10. NP Digital

NP Digital has developed a dedicated AEO and GEO offering as part of its broader search and digital marketing services. 

Its approach covers several important areas of AI Search, including entity optimisation, content structure, technical foundations, authoritative third-party mentions, and AI visibility tracking. 

The agency’s emphasis on entity optimisation is particularly relevant because AI systems need to understand not only individual webpages but also the relationships between brands, products, people, topics, and other entities across the web. 

Best suited to: Mid-market and enterprise brands looking for a large-scale digital marketing partner with dedicated AEO/GEO capabilities. 

How to Choose the Right GEO Agency 

The most suitable agency depends on what problem the organisation is actually trying to solve. 

If the primary challenge is technical retrieval and complex information architecture, an agency with strong technical and information-retrieval expertise may be the better choice. 

If the challenge is brand authority and third-party visibility, look for a team that can combine GEO with digital PR, content, mentions, and authority development. 

For organisations concerned about entity understanding, ask how the agency approaches brand identity, structured data, knowledge relationships, and consistency across external sources. 

Measurement is another important consideration. A serious AI Search programme should establish what is being measured, which prompts or categories matter, how competitors are appearing, and whether visibility is improving across relevant AI platforms. 

Finally, consider scale. A startup may need a focused GEO programme, while an established multinational organisation may require technical SEO, content engineering, entity optimisation, international search, measurement infrastructure, and coordination across several internal teams. 

Conclusion 

GEO is still a developing discipline, and there is no universal playbook that guarantees inclusion in AI-generated answers. Different AI platforms use different systems, data sources, retrieval processes, and response-generation methods. 

That makes the choice of agency particularly important. 

The 10 agencies above represent different approaches to the emerging AI Search landscape. iPullRank stands out for its emphasis on relevance engineering and retrieval. Blue Array combines GEO with a strong organic search foundation and AI visibility reporting. First Page Sage brings a research-heavy perspective. Impression connects GEO with SEO and digital PR, while NoGood approaches AI Search through a broader growth model. 

Directive is particularly relevant for B2B organisations, DEPT® brings GEO into a wider digital ecosystem, and Peak Ace offers strong international search capabilities. NP Digital combines GEO and entity optimisation with a broad digital marketing operation. 

Netsleek takes a more specialised AI Search and Brand Discoverability position, with GEO, AEO, entity optimisation, AI-ready content engineering, technical search, and AI visibility measurement forming part of its broader methodology. 

The important point is not to find a universally “best” GEO agency. It is to find the agency whose methodology matches the organisation’s specific AI Search problem, internal capabilities, markets, competitive environment, and long-term visibility goals.
