GEO (Generative Engine Optimization)

Also known as: Generative engine optimization · AI SEO

GEO is the set of practices that get a brand, product or piece of content found and cited in answers from AI assistants such as ChatGPT, Gemini, Claude and Perplexity.

SEO vs. GEO

SEO competes for positions in a list of links. GEO competes for a mention inside an AI-written answer, which often cites few sources or none at all.

What drives citations

  • Clear, factual, easy-to-extract content (definitions, lists, tables)
  • Structured data (schema.org) and files like llms.txt
  • Authority: mentions and links from trusted sources
  • Letting assistant crawlers read your site

How to measure

Regularly ask assistants the same questions your customers would, and log whether and how your brand shows up.
