What Is Answer Engine Optimization?
Answer engine optimization (AEO) is the practice of optimizing your content so that AI answer engines like ChatGPT, Perplexity, and Google's AI Overviews cite your brand when they generate an answer.
AEO vs SEO: What's Different?
Traditional SEO optimizes to rank a page in a list of links someone clicks. AEO optimizes to be the source an AI answer cites, often without a click. They share the same fundamentals of quality, authority, and structure, but AEO adds extractable formatting, entity clarity, and citation tracking.
How Answer Engines Choose What to Cite
AI models prioritize content that is:
- Clear and direct — answers the question in the first paragraph
- Well-structured — uses headings, lists, and tables
- Authoritative — comes from trusted sources with strong E-E-A-T signals
- Fresh — recently updated content tends to be favored
How to Optimize for Answer Engines
- Write for extraction: Use clear headings, bullet points, and concise paragraphs
- Focus on entities: Make sure your brand name, products, and key people are clearly mentioned
- Structure data: Implement Schema.org markup and create an
llms.txtfile - Monitor citations: Track which AI engines mention your brand and where
