Definition
Answer engine optimization (AEO) is the practice of structuring content so that a system returning a direct answer — rather than a list of links — selects it as that answer.
答案引擎最佳化（AEO）是指把內容結構化，使「直接返回答案而非連結清單」的系統選用它作為答案的實務。
In practice
It is the older of the two AI-search terms and predates generative answers: voice assistants and featured snippets already needed a single defensible answer per query. In generative search the discipline concentrates on three things — question-shaped headings, a direct answer inside the first two sentences of a section, and facts stated once and unambiguously instead of being distributed across paragraphs. The characteristic failure is over-simplification: content written to be extractable but too thin to be trusted ends up extracted by nobody.
它是兩個 AI 搜尋術語中較早出現的一個，早於生成式答案：語音助理與精選摘要本來就需要每個查詢有一個站得住腳的答案。在生成式搜尋中，這門工作集中在三點：以問句形式的小標題、在段落首兩句內給出直接答案、以及把事實一次性講清而不是分散在各段。典型失效是過度簡化：為了可被抽取而寫得太薄、不值得信任的內容，最後誰都不會抽取。
What it is not
- Not GEO. AEO targets one answer slot; GEO targets retrieval and citation inside a synthesis of several sources.
- Not FAQ spam. Pasting questions nobody asks does not create answerability.
- Not a substitute for depth. Extractable and trustworthy are separate requirements, and both must hold.
Status
Emerging. The term is in real commercial use and has a Wikidata item, but no engine publishes a definition and the boundary with GEO is unsettled. Treat it as practitioner vocabulary with a date attached.
