Answer engine optimisation (AEO) is the practice of structuring content so search and AI engines can lift it as a direct answer, in featured snippets, AI Overviews, voice assistants and chat answers.
AEO and GEO overlap heavily. AEO focuses on the answer format: a direct response near the top of the page, clear headings that match questions, and supporting structured data. GEO extends that to brand naming, entity signals and off-site sources across AI engines.
