Answer Engine Optimization (AEO)
Also known as: AEO
What is Answer Engine Optimization?
Answer Engine Optimization (AEO) is the practice of formatting and structuring web content so that answer engines — ChatGPT, Perplexity, Google AI Overviews, Gemini, and Claude — can extract, trust, and cite it directly in a generated answer. Where traditional SEO optimizes for a ranked list of blue links, AEO optimizes to be the source a machine quotes.
In practice, AEO means leading with a direct, self-contained answer to the question a page targets, using clear headings that match how people phrase questions, adding structured data (FAQ, HowTo, DefinedTerm), and keeping facts verifiable and current. Answer engines favor pages that state the answer up front and back it with structure they can parse.
AEO does not replace SEO — it extends it. A page still needs to be crawlable, fast, and topically authoritative to be a candidate for citation. AEO adds the answer-first formatting and machine-readable structure that make a page the preferred source once it is a candidate.
Why it matters
AI answer engines now sit between your content and the user — if they don't cite you, you're invisible even when you rank.
Answer Engine Optimization — FAQ
How is AEO different from SEO?
SEO optimizes to rank in a list of links; AEO optimizes to be the source an AI answer engine cites in a generated answer. AEO builds on SEO — a page must still be crawlable and authoritative — and adds answer-first formatting plus machine-readable structure.
Which answer engines does AEO target?
ChatGPT (with browsing), Perplexity, Google AI Overviews (SGE), Gemini, Claude, and Bing Copilot — any system that generates a synthesized answer and cites sources.
How do I make a page more likely to be cited?
Lead with a direct 2–3 sentence answer, use question-shaped headings, add FAQ/HowTo/DefinedTerm schema, keep facts current and sourced, and cover the topic comprehensively so the engine treats you as authoritative.
