What is Answer Engine Optimisation (AEO)?
AEO definition: how Answer Engine Optimisation works.
Answer Engine Optimisation (AEO) is the discipline of engineering content so that it is returned as the direct answer inside answer-engine surfaces - Google AI Overviews, featured snippets, ChatGPT, Gemini, Perplexity, Claude and the next generation of voice assistants.

Short definition
AEO (Answer Engine Optimisation) is the practice of structuring, formatting and corroborating content so that answer engines - both traditional (featured snippets, AI Overviews) and generative (ChatGPT, Gemini, Perplexity, Claude) - select it as the direct answer to a user query.
What AEO actually optimises for
AEO is selection optimisation. The user asks a question. The engine returns a single direct answer (or a small named set). AEO is the work that makes the brand the named source.
It rewards parsimony, clarity, structured formats (lists, tables, definitions, FAQs), and verifiable third-party corroboration. It punishes vague marketing language.
Core AEO techniques
- Question-led architecture: page structures built around real buyer questions, with answers in the first 300 characters.
- Structured data: FAQ, HowTo, DefinedTerm, Article, Service schema applied with discipline.
- Lift-out formatting: answers in lists, tables and definition blocks that engines extract cleanly.
- Authority signals: bylines, credentials, citations and independent corroboration that engines weight when choosing whose answer to use.
AEO inside the AVO discipline
AEO is the answer-formatting subset of AVO. GEO is the citation-and-inclusion subset. AVO is the overarching discipline that runs both, plus the entity and coherence work that determines whether either is possible.
What is AEO FAQs.
What does AEO stand for?
AEO stands for Answer Engine Optimisation. It is the practice of being returned as the direct answer by AI assistants, AI Overviews and featured-snippet surfaces.
Is AEO different from GEO?
AEO focuses on direct-answer surfaces: AI Overviews, featured snippets, voice assistants. GEO focuses on citation inside generative LLM answers. Most modern programmes run both inside an AVO engagement.
Does AEO matter if I'm not in voice search?
Yes. The same answer-engine selection mechanism powers Google AI Overviews, ChatGPT and Perplexity. AEO is no longer a voice-search niche; it is the dominant discovery surface.
How long does AEO take?
First inclusion in answer-engine surfaces typically within 30-60 days for well-structured topics, depending on the strength of the existing entity and authority signals.
