Answer Engine Optimization: how to get cited by ChatGPT, Perplexity and Claude
To be cited by AI answer engines, write clear, well-structured content that directly answers questions, uses headings and summaries, states facts plainly, and carries strong structured data and entity clarity.
Search is no longer only ten blue links. Answer engines — ChatGPT, Perplexity, Claude, Google's AI overviews — read the web, synthesize an answer, and cite a handful of sources. Answer Engine Optimization (AEO), sometimes called GEO, is the practice of making your content the kind these systems understand, trust and quote.
It overlaps with good SEO, but adds a few things models specifically reward.
How AI answer engines choose sources
Models favor content that clearly and directly answers a question, is well-structured with descriptive headings, states facts and definitions plainly, and is easy to attribute. Ambiguous, meandering or purely promotional pages are hard to quote, so they get left out.
| Signal | Why it helps citation |
|---|---|
| Direct answers | A clear response near the top is easy to quote |
| Clear structure | Headings and lists let models extract cleanly |
| Plain facts & definitions | Unambiguous statements are safe to cite |
| Summaries / TL;DR | A concise summary is quotable as-is |
| Structured data | Schema clarifies entities and meaning |
| Entity clarity | A recognizable, consistent source builds trust |
