Answer Engine Optimization (AEO) is the practice of structuring a website so AI engines like ChatGPT, Perplexity, Claude, and Google AI Overviews can read it, understand it, and quote it directly inside their generated answers. It is what SEO becomes when the click is replaced by a sentence inside an LLM.
AEO makes your content quotable by AI. The basics: answer the user's question in the first one or two sentences, mark it up with schema so engines know what the answer is, and keep a clean llms.txt so engines know which pages on your site matter.
| SEO | AEO |
|---|---|
| Ranks you in a list of links. | Gets you cited inside the answer. |
| Optimized for crawl + keywords. | Optimized for retrieval + quoting. |
| Click is the conversion. | Mention is the conversion. |
