Answer Engine Optimization, Explained

Answer Engine Optimization (AEO) is the practice of optimizing content so that it is retrieved, selected, and cited by AI-powered answer engines when they generate a response. Where SEO competes for a ranked link, AEO competes to be a source inside the answer itself.

AEO, GEO, SEO — the short version

• SEO targets ranked positions in a list of links.
• AEO targets being cited inside an AI-generated answer or answer snippet — Google AI Overviews, featured answers.
• GEO is the generative-model flavour of the same idea — being cited by ChatGPT, Claude, and other LLMs in their generated text.

In practice the three overlap heavily and most working practitioners use the terms loosely. The distinction that matters is the one between ranking a link and being the source of an answer.

The six levers of AEO

1. Content structure — clear sections an engine can navigate.
2. Answer formatting — direct responses up front.
3. Citation quality — credible, verifiable claims.
4. Schema markup — machine-readable structured data.
5. Entity recognition — a consistent, recognizable identity.
6. Topical authority — depth across a cluster, not a single page.

What it means for an agency

AEO is not a replacement for SEO; it is an extension of the same content competence into a new surface. An agency that already does content and technical SEO well is most of the way to doing AEO well. The gap is mindset: optimizing to be extracted and cited, rather than to be clicked.
