Short answer: answer engine optimization (AEO) is the practice of structuring authoritative, quotable content so answer engines — ChatGPT, Perplexity, Google AI answers — cite you as a source instead of a competitor.
Measure your answer-engine presence. Nythral's GEO product tracks how AI answers cite and describe your brand. See geo.nythral.com.
Answer Engines vs Search Engines
A search engine returns links; an answer engine returns a written answer and may cite a few sources. AEO is about being one of those cited sources. The winners are pages that state facts clearly, back them up, and are easy for a model to lift verbatim.
What Answer Engines Reward
An AEO Checklist
| Action | Why it earns citations |
|---|---|
| Answer-first sections | Models lift the crisp statement near the heading. |
| Question-shaped headings | Match how people actually prompt. |
| Structured data | FAQ, HowTo, and Organization schema clarify entities. |
| Sources and dates | Signals reliability the model can trust. |
| Consistent facts | The same claim across your site and third parties builds consensus. |
AEO, GEO, or SEO?
They are layers, not rivals. SEO keeps you findable and crawlable, GEO shapes how models describe you, and AEO earns the citation in the answer. Start with GEO vs SEO, then learn how to rank in ChatGPT.
