# AEO (Answer Engine Optimization)

> AEO is the optimisation of content for AI answer engines such as ChatGPT or Perplexity — in practice largely the same as GEO. What the term actually means.

Synonyms: answer engine optimisation, AI SEO, LLM SEO

AEO puts the answer engine at the centre: systems like ChatGPT, Perplexity or Google AI Overviews answer questions directly instead of showing lists of links. You therefore optimise not for a ranking position, but for appearing as a source in that one answer.

The term circulates alongside GEO, LLM-SEO and AI-SEO — yet almost always describes the same practice: clear, fact-rich, machine-readable content that an AI system can understand and cite correctly. Apply the principles once and you cover all of these labels at the same time — what matters is clean structure, verifiable facts and freshness, not the acronym.

For businesses this means: the question is not which abbreviation to pick, but whether your website is readable for answer engines — from opening hours to service descriptions. That is exactly what an AI-ready digital foundation delivers as standard.
