Pamela Toro Generative Engine Optimisation (GEO) isn’t just about climbing Google rankings anymore. It’s about gaining visibility across AI platforms, increasing your presence in generative responses and preparing for the future of search. In a world where more users are turning to tools like ChatGPT, Claude and Perplexity for answers, choosing the right GEO agency means choosing a partner who understands AI systems, adapts to shifting search behaviours, and delivers measurable results.
The shift from traditional SEO to GEO marks a significant evolution in organic search. While Google is still a major player, generative AI platforms have created new opportunities for discovery. This requires specialist knowledge in areas like prompt engineering, training data optimisation and understanding how large language models (LLMs) source and structure information.
The best GEO agencies don’t just optimise for search engines. They optimise for entire ecosystems, ensuring your brand shows up where it matters most: in AI-generated answers, summaries and sources of authority.
So if you’re looking for your next GEO agency, check out the list below, where we spotlight eight standout GEO agencies in the UK that are pushing boundaries in generative search.
