Why Does This List Matter in 2026?
Search has changed more in the past 18 months than in the previous two decades combined. This has happened because AI-driven search platforms like ChatGPT, Perplexity, and Gemini provide a better way to discover information at the top of the sales funnel.
A McKinsey survey found that around 40-50% of consumers in top sectors (including grocery, consumer electronics, travel, wellness, beauty, financial services, etc.) now intentionally use AI-powered search tools (such as AI chatbots and AI search features) to make purchasing decisions in 2025. This makes it evident why ranking on generative engines is crucial for businesses.
Today:
ChatGPT usage is catching up with traditional Google search
Perplexity summarises complex problems and creates solutions in a single answer
Google AI Overviews summarises thousands of search results into a simple paragraph
Microsoft Copilot rewrites and optimises documents for businesses everywhere
This shift has created a new marketing discipline: Creating brand visibility inside generative engines, AKA GEO (Generative Engine Optimisation).
While SEO remains essential, brands now need to optimise for brand mentions and citations in LLMs.
We have curated this guide after a thorough analysis of the UK-based GEO agencies to help UK businesses understand:
Which agency is the best partner for your business size and growth goals?

Common Mistakes When Choosing a GEO Agency
Mistake 1 - Choosing an SEO agency that simply added “GEO” to their service page. True GEO requires a focused approach.
Mistake 2 - Confusing digital PR with GEO. PR supports trust, but cannot replace structured GEO optimisation.
Mistake 3 - Choosing a full-service agency while expecting GEO depth. Specialism matters at this stage of AI-search evolution.
Speak to Buried. We not only offer effective and tailored GEO strategies for your business but also ensure you are perfectly informed at every step of the process. If you think you need to strengthen your SEO game first, worry not - at Buried, we have the expertise to assist you with end-to-end SEO and GEO optimisation.
Why Buried is Your #1 Choice in the UK
Buried earns the top spot (with a whopping 5-star review on Google) because it operationalises GEO (Generative Engine Optimisation) the way others only describe it.
While many UK agencies still treat AI search as a buzzword or an extension of traditional SEO, Buried built its services around organic search with a specialised focus on both GEO and SEO services.
Our approach recognises that GEO differs from SEO in critical ways. GEO focuses on being cited and referenceable by generative engines (ChatGPT, Perplexity, Google AI Overviews, Copilot), not just ranking pages in traditional SERPs.
We also invest our efforts in producing in-depth resources explaining GEO, its functionalities, and efficient GEO tools to drive knowledge-led decision-making.
Case Study - Making Pinter Visible in ChatGPT
At Buried, our experts analysed pinter.co.uk, a home beer brewing product site with strong traditional SEO but poor generative engine visibility. Despite ranking highly in Google UK for relevant keywords, the brand didn’t appear in AI search responses across nine different prompts, signalling a gap in efficient GEO implementation.
Buried identified that the product wasn’t linked to its core category in training data. The proposed GEO strategy included targeted comparison content, educational articles, category alignment, third-party “best of” listings, and social/UGC (User-Generated Content) signals to strengthen how AI models associate the brand with its category.
To get an in-depth understanding of how we analysed the problem and created a GEO strategy for Pinter, take a look here.
The combination of strategy, methodology, GEO expertise, and thought leadership makes Buried the UK’s most robust partner for brands aiming to dominate organic search.
