Answer engine optimization (AEO)
Also: AEO, answer engine optimisation
AEO and GEO are often used as synonyms. A useful split is that GEO describes the work and AEO describes the result a buyer cares about: being named in the answer.
Measuring AEO starts with a fixed set of buyer questions across research, comparison, recommendation and buying intent. Each question is run several times on each AI app, because the same question can return a different answer minutes later. Results are reported per app, since ChatGPT, Google AI Mode, Gemini and Perplexity often cite very different sources for the same question.
