Answer Engine Optimization
Overview
Answer Engine Optimization (AEO) is the practice of optimizing content so that it is surfaced as the direct answer to a query by an "answer engine" — a system that returns one synthesized or extracted answer rather than a ranked list. The category predates large language models: it encompasses featured snippets, voice-assistant answers, and "people also ask" boxes, and has been extended to cover AI-generated answers.
AEO is commonly treated as broader than GEO in time and surface — it includes pre-LLM answer surfaces such as featured snippets and voice search — but the two terms are frequently used interchangeably by practitioners, and no standards body has fixed the boundary.[1]
How it works
AEO techniques aim to make a single passage the most extractable answer to a question:
- Question-and-answer formatting and FAQ schema markup.
- Concise, self-contained answer passages placed near the top of a page.
- Structured data (schema.org) that disambiguates entities and facts.
- Alignment with conversational and voice query phrasing.
| Term | Scope | Typical surface |
|---|---|---|
| AEO | Broad: traditional + AI answer surfaces | Featured snippets, voice, AI answers |
| GEO | Narrow: generative-model answers | ChatGPT, Perplexity, AI Overviews |
| Traditional SEO | Link ranking | Results pages |
AEO is not synonymous with GEO: AEO includes pre-LLM answer surfaces (featured snippets, voice) that involve no text generation, whereas GEO is specific to systems that synthesize answers. In practice the terms overlap heavily and are often marketed as equivalents.
Examples
- A concisely written definition that wins the Google featured snippet for a query is an AEO outcome on a non-generative surface.
- The same passage being quoted inside a ChatGPT answer is a GEO outcome.
