What Is Answer Engine Optimization (AEO)?
What AEO means, how it relates to SEO, and how to write content that answer engines choose.
Answer engine optimization (AEO) means shaping your content so that search engines and AI assistants can use it as a direct answer โ in featured snippets, People also ask boxes, voice assistants, AI Overviews and chat tools like ChatGPT or Perplexity.
AEO, SEO and GEO
- SEO โ the broad practice of helping pages rank and get clicks in search engines.
- AEO โ focuses on being selected as the answer itself, across search features and assistants.
- GEO (generative engine optimization) โ focuses on AI-generated answers and citations specifically. See what GEO is.
They overlap heavily. Good AEO is mostly good SEO with extra attention to clear, direct answers.
Where answers appear
- Featured snippets at the top of Google results.
- People also ask boxes.
- Google AI Overviews.
- Voice assistants reading out an answer.
- AI chat tools that cite web sources.
How to optimise for answers
- Answer first. Put a concise answer (40โ60 words) directly under a question heading.
- Use the question as the heading, phrased as people ask it.
- Then expand with details, steps and examples.
- Format steps as numbered lists and comparisons as tables.
- Define terms clearly the first time you use them.
- Keep facts current and sourced.
- Add structured data where it accurately describes the page.
Check and improve answer passages with the AI Overview optimizer and the featured snippet optimizer.
Find the questions to answer

The click question
Direct answers can reduce clicks for simple facts. Aim AEO at questions where your answer leads naturally to more: a process, a comparison, a tool, a product. The answer earns visibility; the depth earns the visit.
A worked example
An Irish home-energy advice site rewrote its top guides so each section opened with a two-sentence answer under a question heading, followed by a comparison table. Several pages won featured snippets and began appearing as sources in AI Overviews, and visits to its savings calculator rose, because readers wanted the personalised numbers behind the short answer.
An AEO checklist for each page
- One clear question in the main heading or a subheading.
- A concise answer directly underneath.
- Supporting detail, steps or examples after the answer.
- A table or list where the answer has several parts.
- An updated date for information that changes.
- An author or source that shows expertise.
- Links to deeper resources for readers who want more.
Apply it first to pages that already rank on page one โ they are the most likely to be chosen as answers.
