Answer Engine Optimization, or AEO, is the practice of structuring content so it can be easily understood, extracted and cited by AI-powered answer engines — tools like ChatGPT, Perplexity and AI-generated search summaries.
Where SEO optimizes for rankings on a results page, AEO optimizes for something slightly different: being the source an AI system chooses to pull from when generating a direct answer.
The core principles of AEO
- Structure content around clear questions and direct answers
- Use headings, lists and definitions that are easy to extract
- Build topical authority instead of isolated, one-off pages
- Keep factual information (names, locations, offerings) consistent everywhere it appears
- Make expertise and sourcing visible, not just implied
Why it matters now
AEO isn't a replacement for SEO — it's an extension of it. As more discovery moves through conversational, AI-driven interfaces, businesses that structure their content clearly will have an advantage whether a person lands on their page directly or encounters their brand through an AI-generated summary.
