What Is Answer Engine Optimization (AEO)?

What AEO means, and how it differs from GEO

Answer engine optimization is about one deliverable: a passage that makes sense when it is lifted out of its page. If an assistant quotes only those 50 words, the reader should still get a correct, complete answer.

No standards body defines the term, and vendors use it for different things. Some mean winning featured snippets and voice answers, others mean being cited by ChatGPT or Perplexity. Google's guide groups AEO and GEO together as SEO. For this site we use a working split, which is ours and not an industry rule:

• AEO is the writing and page structure that makes a quotable answer.
• GEO is the wider effort to be retrieved and chosen as a source, including access, evidence and mentions. The GEO explainer covers that side.

You need AEO craft for GEO to have anything to work with.

How long should an answer passage be?

Aim for 30 to 70 words as our working rule. For context, Pew found the median Google AI summary in March 2025 ran 67 words (range 7 to 369), in its analysis of 12,593 summaries. That is the length of a whole summary on one engine, not evidence of the best passage length.

We follow this on every guide on this site. Each page opens with a standalone answer of roughly 30 to 65 words, written so it still works with nothing around it. It is the same passage we would want quoted.

The anatomy of a passage that can be quoted

None of this is a trick. Google's own guide advises clear headings and paragraphs, and says there is no ideal page length.

A worked example

This example is illustrative. The clinic and the details are invented.

Question: Does a Limassol dental clinic see emergency patients?

Weak answer: "We care about our patients and offer a range of services including emergency care, so please get in touch to find out more."

Quotable answer: "Yes. Our Limassol clinic keeps two same-day emergency slots open every weekday morning, for toothache, broken teeth and lost fillings. Call before 10:00 to be seen that day. Out-of-hours emergencies are not covered, so contact the emergency services for facial swelling or bleeding that will not stop."

The second version answers yes or no, gives a mechanism and a deadline, names what is excluded, and tells the reader what to do instead. It runs to 55 words.

Where FAQ sections and markup fit

Visible question-and-answer sections are a good home for AEO passages, because each answer is already separated and titled. Marking them up is optional. Google states that its AI features need no special structured data, and that markup should match the visible text. If your platform adds FAQ markup, keep it consistent with the page, and do not treat it as the thing that earns a citation. The wider schema markup guide covers when structured data is worth the effort.

What the first sentence must contain, by page type

The pattern is the same everywhere, but the content of the first sentence changes with the page.

A pricing page is the hardest to get right, because owners dislike publishing numbers. An assistant asked "how much does X cost in Limassol" will name a figure from somewhere. If your page gives only "contact us for a quote", it supplies nothing, and the figure may come from a competitor, a directory or an out-of-date listing. A range with its conditions is more useful to the reader and gives you some control over what is said. It is also honest to say what you cannot predict.

A checklist for one service page

1. List the questions a buyer asks before they contact you. Use sales calls and inbox history, not guesses.
2. Give each question its own heading.
3. Answer in the first sentence, then explain.
4. Include a price range, duration or condition wherever one exists.
5. Name your source for any figure you did not produce yourself.
6. Say who the answer does not apply to.
7. Check the page for jargon that only your team uses.
8. Confirm the page is indexed and not carrying a nosnippet directive.
9. Add a date, and update the date only when the content changes.
10. Record the page and its questions in your tracking sheet, as described in how to track your brand in AI answers.

When AEO effort is wasted

• Pages with nothing to answer. A homepage hero or a gallery has no question behind it.
• Facts that change every week. If a price changes weekly, link to a live page and keep the passage about the method.
• Passages split across tabs or accordions that need scripts. Keep important content in plain text on the page.
• Pages that are not indexed. Fix that first. Our technical SEO guide lists the checks.

AEO does not promise a citation. It removes reasons for being skipped. For the full picture of what is documented and what is not, read the AI search optimization guide, or see how our AI search service applies this to your site. Choose one page and write its answer passage today.
