What is Generative Engine Optimisation (GEO)?

Updated 26 October 2026

Generative Engine Optimisation (GEO) is the work of getting a brand cited, recommended and described accurately in answers written by AI: ChatGPT, Google AI Overviews and AI Mode, Perplexity, Gemini, Claude and Copilot. You will also see it spelt optimization, and sold as AI search optimisation, AI SEO, answer engine optimisation (AEO) or LLM optimisation. The labels differ; the job is largely the same.

Why it exists

A growing share of questions that used to start on a search results page now end in an AI answer. That answer usually names a handful of brands and cites a few sources. If your brand is not among them, the buyer may never see a list of links at all. GEO tries to change which brands and sources the answer picks.

What a GEO agency does

Most UK agencies in the ranking describe the same building blocks:

  • An AI visibility audit: a set of prompts your buyers actually ask, run across several assistants, to see whether and how the brand appears.
  • Content written to be quoted: direct answers, clear facts, comparisons and FAQs that a model can lift and attribute.
  • Entity and structured data work: making sure search engines and models identify the brand without ambiguity, with consistent facts across the web.
  • Digital PR: mentions on the third-party sources AI answers rely on, such as trade press, reviews and published rankings.
  • Tracking: citations and share of voice over time, often with a named tool such as Peec AI or Profound.

Of the 38 agencies scored by the rules, 34 have a page dedicated to their GEO service, and 9 publish a quantified AI-search result.

GEO and SEO

GEO does not replace SEO. AI search engines still read the web, and many of them start from pages that already rank. What changes is the measure: being the source that is quoted, rather than the link in position one. See GEO vs SEO for the details.
