Answer engine optimisation, or AEO, is writing content so it can directly answer the specific questions people ask AI assistants and search engines.
AEO overlaps closely with GEO, but focuses specifically on matching how people phrase real questions, such as what a term means or how to choose between two options, with headings and answers that mirror that phrasing. A page organized around the actual questions an owner would ask is easier for both a person and an AI system to use.
