What is answer engine optimisation (AEO)?
How to become the answer people see first: in featured snippets, voice assistants and Google's AI Overviews.
Short answer
Answer engine optimisation (AEO) is the practice of shaping your content so search engines and AI assistants use it as the direct answer to a question. That answer might be a featured snippet, a voice assistant's reply, or a linked source in Google's AI Overviews and AI Mode. AEO builds on SEO, because you still need pages that rank. It adds question research, answer-first writing and structured data.
Where do answers appear?
- Featured snippets: the boxed answer above Google's regular results, quoted from one page.
- People also ask: the expandable questions in Google results, each answered from a page.
- Voice assistants: Google Assistant, Siri and Alexa read out one answer, not ten links.
- AI Overviews and AI Mode: Google's AI-written summaries, with links to the pages they draw on.
- Bing and Copilot: Microsoft's answers and its Copilot assistant, which cite web sources.
In every case, one source gets the attention. Everyone else gets less of it.
How is AEO different from SEO?
SEO asks how to rank on page one. AEO asks how to become the answer. The difference shows in the writing.
A page built for rankings alone often warms up for three paragraphs before it says anything. A page built for answers says it in the first sentence, then explains. Both need the same technical base and the same authority. For the full comparison, read SEO vs AEO vs GEO.
How do you optimise for answer engines?
- Collect the real questions. Look at People also ask, your Search Console queries, sales calls and support emails. Write down the exact wording people use.
- Give each question a home. One clear heading per question, phrased the way people ask it.
- Answer first. State the answer plainly in the first sentence or two, so it makes sense if quoted alone. Then add detail, examples and exceptions.
- Use the right shape. Steps as a numbered list. Comparisons as a table. Definitions as "X is…".
- Mark it up. Add structured data such as Article, Organization and BreadcrumbList, so machines can tell what the page is and who published it.
- Date it and keep it current. Show when the page was published and updated, and update it when the facts change.
- Keep it readable by machines. The answer must be in the page's HTML, not loaded later by a script or locked behind a login.
Does structured data help AEO?
It helps machines understand a page. It is not a shortcut. Google says its AI Overviews and AI Mode need no special markup, and it has cut back several rich results over the years, including FAQ results for most sites in 2023.
Use structured data to describe what is true and visible on the page: the article, the author, the organisation, the breadcrumbs. Don't mark up content readers can't see.
How do you know AEO is working?
- Featured snippets you hold, which most rank trackers report.
- Your pages appearing as sources in AI Overviews for your target questions, checked by hand or with a tracker.
- Search Console impressions and clicks on question-style searches. Google counts AI Overviews and AI Mode in the same Performance report as regular web results.
- Leads who say they found you through a search answer.

Is AEO the same as voice search optimisation?
Voice search is one part of it. AEO covers every place a single answer is shown: featured snippets, voice assistants and AI summaries.
Do I need a separate page for every question?
No. Group related questions on one page, with a heading for each. Give a question its own page only when it has its own search demand and needs a long answer.
Can a small site win featured snippets?
Yes, but it has to rank first. Snippets come from pages already on page one for the query. Among those, a clear, well-structured answer gives a smaller site a real chance.
Will AEO reduce my clicks?
For simple facts it can, because the answer is the whole need. For questions that lead to a decision, being the quoted source builds trust, and the clicks that do come are better informed. If you're not the answer, a competitor is.
