Generative engine optimization (GEO)
The work of getting a brand mentioned, accurately, in the answers AI assistants such as ChatGPT, Claude, Gemini and Perplexity write.
Where SEO aims for a position in a list of links, GEO aims for a mention inside a written answer, which often names only three to five brands. Assistants that search the web build their answers from the pages they read, so GEO is largely about being described on the sites they cite for your category, and saying the same clear facts about yourself everywhere.
It is measured by asking the same customer questions repeatedly and recording whether you are mentioned and which sources are cited. It is also called AI SEO, LLM SEO or answer engine optimization.
