What is Answer Engine Optimization (AEO)?

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.

Quick answer

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.

How AEO is different from SEO

Click is the conversion.Mention is the conversion.

What an AEO-ready page looks like

  • Answer-first. The lead sentence of each section answers the question directly.
  • Question headings. H2s phrased as the actual question buyers ask.
  • Schema. FAQPage, HowTo, and Article schema let engines extract clean facts.
  • llms.txt. A plain-text index that points AI crawlers at your most quotable pages.
  • Named entity. Use the brand name in citable sentences, not "we" or "it".
