What is AEO (Answer Engine Optimization)?

Answer-engine optimisation, explained for business owners — what it is, how it differs from SEO, and why it matters now.

What does AEO stand for?

AEO stands for Answer Engine Optimization. An “answer engine” is any AI tool that responds to a question with a direct, written answer rather than a page of links — ChatGPT, Perplexity, Claude, Google AI Overviews, Gemini, Grok and Copilot. AEO is the work of making sure that when one of these tools answers a question in your category, it names and cites you.

How is AEO different from SEO?

They share the same goal — being found — but the “result” looks different. SEO optimises to rank in a list of blue links. AEO optimises to be the source an AI quotes in a single answer.

The good news: the foundations overlap. A clear, fast, well-structured, authoritative site helps both.

Why does AEO matter now?

A growing share of searches never reach a results page — people ask ChatGPT or Google’s AI Overview and read the answer directly. If the AI doesn’t cite you, you’re invisible for that question, no matter how well you rank in classic search. AEO is how you stay visible as search behaviour shifts.

How do answer engines decide what to cite?

No engine publishes its exact recipe, but in practice they favour sources that are:

• Clear and specific — the page directly answers the question being asked.
• Well-structured — descriptive headings, short paragraphs, lists and tables the model can parse.
• Trustworthy — the site (and the wider web) treats it as a credible source on the topic.
• Machine-readable — crawlable, fast, and marked up with structured data and llms.txt.
• Current — the information is up to date.

How do you improve your AEO?

1. Answer one specific question per page, clearly, near the top.
2. Structure content for extraction — headings phrased as questions, lists, and definitions.
3. Add schema markup so engines understand what each thing on the page is.
4. Earn mentions and citations from other sites the AI already trusts.
5. Keep the site fast, crawlable and free of content that only loads with JavaScript.
6. Track which prompts cite you, and fix the gaps. Here’s the step-by-step.

How do you know if AI is citing your business?

You can’t see it in Google Analytics — AI answers don’t always send a click, and when they do it’s hard to attribute. The only reliable way is to track it directly: run the questions your customers ask through each engine and record where you appear.
