What Is AEO (Answer Engine Optimization)
AEO (Answer Engine Optimization) means making a page the preferred source for direct answer formats such as Q&A, voice, and AI summaries. The core of AEO is a self-contained, verifiable answer, not turning a page into a FAQ list.
Definition
This site's working definition: AEO is writing one specific question into a complete answer that can be extracted directly, with clickable evidence, so the page meets the conditions to become a direct answer source.
Whether AEO is done is judged by three things: the original question sentence appears on the page, the answer is self-contained within one paragraph, and the evidence link reaches a primary source within three clicks.
Boundaries: what it is easily confused with
| Easily confused concept | Key difference |
|---|---|
| GEO | GEO covers citations and description overall; AEO handles only the direct answer format |
| FAQ stuffing | The number of Q&A entries does not equal extractability; Q&A without evidence cannot be verified |
| SEO featured snippets | Featured snippets belong to search results; AEO targets Q&A and generative answers |
Common misconceptions
- Turning a page into a Q&A list and calling AEO done. When entries depend on each other, extracting any single one fails.
- Writing answers for peers. An AEO answer must answer the asker first, then add background and exceptions.
- Writing answers without evidence. An answer with no source is only a statement and is downgraded to a mention.
Basis and verification
