Answer Engine Optimization (AEO)
Also called: AEO
Answer engine optimization is the practice of making a business legible and credible enough that AI systems name it inside a generated answer.
Traditional search optimization competes for a position in a list of links. Answer engine optimization competes to be one of the handful of names an assistant mentions when it answers a question directly — a fundamentally narrower target, because an answer names two or three businesses rather than showing ten.
The work divides into three parts: making the entity unambiguous, so a model knows what the business is and who it serves; making the content retrievable, so it can actually be read and quoted; and building corroboration, so claims are supported by sources beyond the business's own domain.
Why it matters
When an assistant returns one recommendation instead of a page of options, the difference between being named and being absent is the difference between a customer and no customer. There is no equivalent of position four.
An example
Suppose a dental practice in Leeds wants to be named when someone asks ChatGPT for a family dentist nearby. AEO work would confirm that ChatGPT's search crawler can reach the site, that the practice's name, address and services are stated identically in structured data and on the page, that the site answers the questions patients actually ask, and that independent sources — a directory listing, a local news mention — corroborate what the site claims.
Common mistakes
- Treating it as a content-only exercise. Writing more articles does nothing if crawlers are blocked or the content only appears after JavaScript runs.
- Measuring it with a single query. Answers vary between sessions and phrasings, so one test proves very little either way.
- Assuming it replaces SEO. Most answer engines retrieve from search indexes, so being indexable remains the prerequisite.
Questions
- Is AEO different from SEO?
- It overlaps heavily. Both depend on being crawlable, indexable and clearly structured. The difference is the target: SEO competes for a position in a list, AEO competes to be one of the two or three names an assistant uses in its answer. Entity clarity and third-party corroboration matter more in AEO than in traditional ranking.
- How long does AEO take to work?
- Engines that retrieve live pages can reflect changes within days to weeks once the pages are indexed. Anything that depends on a model's training data moves on the model's retraining cycle, which is months. Most practical AEO work targets the retrieval layer for that reason.
