What Is AEO (Answer Engine Optimization)?

AEO (Answer Engine Optimization) is the practice of optimizing to appear in answer engines: systems that return a direct answer instead of a list of links. It covers ChatGPT, Perplexity, Google AI Overviews, Google's featured snippets, and voice assistants.

The premise is simple: more and more searches are resolved without a click. The user gets the answer right inside the search engine or chatbot. AEO works to make sure that answer is yours (or that your site is cited as the source).

AEO and GEO: is there a difference?

In practice the two terms are used almost interchangeably. The nuance:

• AEO focuses on being the answer (it includes voice search and featured snippets, not just generative AI).
• GEO focuses on the generative engines (LLMs that synthesize a response).

If you optimize well for one, you usually make progress on the other. That's why AEON42 treats them together. Want the breakdown? Read SEO vs GEO vs AEO.

Concrete AEO tactics

1. Answer the question in the first 2–3 lines. Engines extract the most direct passage. Don't bury the answer halfway down the page.
2. Structure for extraction. Question-shaped headings, numbered lists, tables, and "what it is / how to do it" blocks.
3. Publish FAQs with short, verifiable answers, marked up with FAQPage schema.
4. Structured data. Organization, WebSite, Article, FAQPage, and BreadcrumbList help engines understand the entity and the context.
5. Allow AI crawlers and publish an llms.txt.
