AEO (Answer Engine Optimization)

AEO (Answer Engine Optimization) is the optimization of content for answer engines — ChatGPT, Perplexity, Gemini, Alexa, Google AI Overviews — that deliver a direct answer rather than a list of links. Its goal is to be the answer, not just a result.

AEO (Answer Engine Optimization) is the art of structuring content so an answer engine — ChatGPT, Perplexity, Google AI Overviews, or a voice assistant — selects it as the direct answer to a question. Rather than aiming for a position in a list of links, AEO aims for the answer itself.

How AEO works

Answer engines extract short, self-contained passages. AEO-optimized content answers a question explicitly in the very first sentence, in the "X is…" format, within a block of around 150 words. It relies on clear questions as headings (H2/H3), lists, comparison tables and schema markup — notably the FAQPage schema — which helps the machine isolate the answer.

A concrete example

A page titled "How much does an SEO engagement cost?" followed by a complete, data-backed answer in two sentences is far more likely to be picked up by an AI Overview than a long paragraph buried in context. The question/answer structure is the heart of AEO.

Why it matters

As search shifts toward single answers, being "the answer" becomes more valuable than being "a result." AEO is part of a broader GEO approach and is reinforced by strong topical authority. To put it into practice, see our GEO agency.

Key takeaway

AEO rewards clarity: a direct answer, from the very first sentence, with no detours.

FAQ

Frequently asked questions

AEO optimizes for answer engines in general (including voice search and snippets). GEO focuses on generative engines (ChatGPT, Perplexity, Gemini). In practice, AEO is a building block of GEO.

Specializing in e-commerce in Europe, it's essential for our online stores to be listed by major retailers such as ChatGPT, Gemini, and Claude. This is now the case, and we are very pleased to have partnered with Luwiz, a local agency in Occitanie.
