Best AI Search Optimisation Agencies for UK Brands

AI search optimisation has moved beyond experimentation into a core visibility strategy. As platforms like ChatGPT, Perplexity, Gemini, and Google’s AI Overviews increasingly shape how users discover information, brands are no longer competing just for rankings but for inclusion in AI-generated answers.

This shift rewards agencies that understand entity optimisation, structured data, content retrievability, and how large language models select and cite sources.

The agencies below are actively working within this evolving space, helping brands adapt to AI-led discovery.
