Answer Engine Optimization (AEO)

What is Answer Engine Optimization (AEO)?

AEO is what SEO becomes when the result page stops being a list of links. When a buyer asks ChatGPT, Perplexity, Google AI Overview or Copilot a question, the engine reads a set of sources and writes one answer, citing a handful of them. Being cited is the new ranking. The tactics differ from classic SEO in emphasis rather than in kind: answer the question literally and immediately under a heading that matches how it was asked, keep the answer self-contained so it survives being lifted out of context, mark the page up with schema so the machine does not have to infer structure, and make factual claims specific and attributable. Two things make AEO awkward to measure. Citations often produce no click, so traffic understates influence, and every engine surfaces sources differently. The teams that do well treat AEO as brand presence inside the answer layer, and track citation share rather than sessions.

Why it matters

• Buyers increasingly finish their research inside an AI answer and arrive already shortlisted.
• Citation is winner-takes-most — a generated answer names three sources, not ten blue links.
• The work compounds with SEO rather than competing with it, since both reward clear, structured, factual pages.

Use cases

• Definitional content. Glossary entries written so an engine can lift the definition intact.
• Comparison pages. Structured 'X vs Y' content that answer engines quote when asked to compare vendors.
• Citation tracking. Monitoring which prompts surface your brand and which surface a competitor.
