As a marketing manager exploring the frontier of search today, you are likely facing the question: how do my content, technical SEO and digital PR adapt for the world of generative AI and large-language-model (LLM) driven search? That is where Generative Engine Optimisation (GEO) comes in. This is essentially the set of strategies designed to position your brand or content to be seen and cited by next-generation search tools (e.g., chat interfaces, answer-engine modules, AI summarisation features).
Below you will find: how we selected the agencies; a detailed list of 20 top agencies offering GEO services; and key questions you should ask before engaging one.
Methodology
To compile this list we applied the following criteria:
• The agency must clearly list a GEO, AEO (Answer Engine Optimisation) or LLM-optimisation service on its website.
• There must be visible indicators of capability such as published guides, case studies or third-party recognition in the past 12-18 months.
• The agency must cater to mid-market or enterprise brands with measurable ambitions for emerging search channels.
• The information must be current and publicly visible (published in 2025).
By using this framework, we have gathered a list of agencies with both declared capability and visible practice. For a marketing manager or business owner, this helps to filter vendors that are ready for the realities of AI-driven search rather than simply talking about it.
Here are the 20 agencies that are getting GEO right.
1. The SEO Works
Based in the UK also with presence in the USA, The SEO Works offers a dedicated GEO service covering strategy, content and technical readiness for generative search. It is a solid choice for brands seeking a comprehensive partner with an integrated search programme. They’ve published a whitepaper on ChatGPT and SEO, and are a thought leader in how AI is changing search and content. Their approach makes sure GEO supports good strategy, without losing sight of brand voice or what people are actually looking for. They’re a Google Premier Partner and have won several awards, including at the Global Agency Awards and UK Digital Excellence Awards. For companies that want to stay ahead as search and AI continue to shift, The SEO Works is a solid and trusted choice.
Why pick them: Clear service page; good fit for UK and international brands; ability to link standard SEO and GEO outcomes.
2. Be The Anwer
Be the Answer is a specialist SEO agency that helps brands show up in AI-driven search results, not just traditional ones like Google. They focus on making sure AI tools like ChatGPT, Perplexity, and Gemini pull accurate information about your brand when people ask questions. They do this through a newer approach called Answer Engine Optimisation (AEO) and Generative Engine Optimisation (GEO). Their in-house platform, Autopilot Visibility Engine, tracks where and how often your brand is mentioned by AI, while their strategy team works to keep your content technically sound and easy for AI to understand.

What to ask when selecting a GEO agency
When you contact one of these agencies (or others), here are the key questions to evaluate fit.
- What definition of GEO/AEO/LLM-search do they operate with, and how do they differentiate from traditional SEO?
- Do they track citations, answer-engine mentions or LLM-driven visibility, and what metrics do they use?
- What is their approach to content in a generative context (e.g., structured data, entity modelling, conversational form, summarisation)?
- How do they address technical readiness (structured markup, crawlability, knowledge graphs) for models that ingest and summarise content?
- Can they provide case studies or outcomes (even pilots) where brands have improved their appearance or citability in AI-driven search formats?
- How will they integrate GEO into your broader search & content strategy (not as a bolt-on)?
- What is the effort & resource expectation from your side (content refresh, tech changes, measurement, reporting)?
- How do they approach multi-market or multilingual GEO work if your business operates globally?
- What are their pricing models (pilot vs full-programme vs retainer) and how do they ensure ROI given the relative novelty of GEO?
Final thoughts
GEO is shaping up to be a key area of competitive advantage for brands that want to lead in search when generative and conversational formats become dominant. As a marketing manager you want a partner who not only understands traditional SEO but is actively working with the signals and formats of AI-driven platforms. The agencies above provide a strong starting point.
