What is answer engine optimization (AEO)?

TL;DR

Answer engine optimization (AEO) is the practice of optimizing content so answer engines like Perplexity and Google AI Overviews select and quote it directly in their synthesized answers. Where SEO targets a position in a results list, AEO targets inclusion as a cited source inside an answer.

Definition

AEO covers the content and structure choices that make a page likely to be retrieved and quoted by an engine that synthesizes a written answer: answer-first openings, direct claims an engine can lift, clean structure, and crawlability. The unit of success is a citation — the engine used your page and links it.

AEO vs GEO

The terms overlap heavily and are often used interchangeably, but they emphasize different things. GEO is the broader discipline of earning inclusion in AI answers — mentions, recommendations, and citations across all generative engines. AEO is narrower and older in lineage: it predates chatbots, rooted in optimizing for featured snippets and voice-assistant answers, and it focuses specifically on being the source an engine quotes.

In practice a team doing GEO is also doing AEO. The distinction matters mainly when comparing tools and advice: AEO advice leans toward content structure (schema, Q&A formatting, concise answers), while GEO advice adds brand-level work (entity consistency, share of voice, third-party presence).

AEO vs SEO

SEO competes for positions on a results page; AEO competes for a citation slot inside one answer. The overlap is crawlability and authority. The divergence is structure: an AEO-optimized page leads with a self-contained answer an engine can lift verbatim, while a classic SEO page can afford to bury the answer under context. See GEO vs SEO for what carries over.

How AEO is measured

The same way GEO is: prompt monitoring across the answer engines you care about, scored by citation rate and brand mentions. AEO work is proven when citation rate rises on the prompts you targeted.
