answer engine optimization

Also called AEO

Definition

Answer engine optimization is the practice of shaping a page so that an AI assistant, a voice assistant or a featured snippet can lift the answer straight out of it. In practice that means putting a short, direct answer under a heading that matches the question, then supporting it with detail, so the page can be quoted in one piece.

AEO overlaps almost entirely with generative engine optimization. If a distinction helps, AEO is about the shape of each answer on the page and GEO is about the business being chosen at all. Both start with writing for the question rather than the keyword.

Short version: say the answer first, then earn it.
Why it matters for your business

The page that answers in one breath
is the page that gets quoted.

Most small-business pages bury the answer. The question is in the title, three paragraphs explain why the question matters and the answer arrives near the bottom, if at all. A person skims past. An AI assistant quotes the competitor who said it in the second sentence. Moving the answer up costs nothing and is the highest-return edit on most sites.

It also helps the people who still click. Pages that answer first keep visitors longer and convert more, because the reader trusts the page before they reach the pitch. The same change serves the AI Overview, the featured snippet, the voice assistant and the human.

What you are being sold: "AEO content packages", often a pile of FAQ pages written for machines. One good answer per real question, on the page that should rank for it, beats fifty thin ones. If a proposal counts pages rather than questions answered, ask why.

Example

A plumber's page,
rewritten to answer first.

Before

The page titled "Boiler losing pressure?" opens with a paragraph about the company's twenty years of experience, a second about why pressure matters and a third asking you to call. The answer, that you can top it up yourself with the filling loop and when to stop and call someone, is nowhere on the page.

After

Same address, new order. Under the heading "Why is my boiler losing pressure?" the first two sentences give the two common causes. The next block says how to top it up safely and the one sign that means stop and call. Then the service area, a named engineer and the call button. A voice assistant now reads the first two sentences aloud, an AI answer cites the page and the people who click already trust it.

/boiler-losing-pressure/ H2 Why is my boiler losing pressure? Two sentences. The answer. H2 How to top it up safely H2 When to stop and call
How to check it on your site

Four checks, all free.

Tick each one as you go. 0 of 4 checked on your site.

  1. Read the first two sentences

    Open your busiest article or service page. Do the first two sentences under the main heading answer the question in the title? If you have to scroll to find the answer, so does everyone and everything else.

  2. Search the question in Google

    Type the question your page targets. Is there a featured snippet or AI Overview, and whose words are in it? Open that page and note where its answer sits. It is almost always in the first lines.

  3. Ask a voice assistant

    Ask your phone's assistant the question out loud. It reads one source. If that source is not you, the shape of your page is part of the reason.

  4. Check the question matches the heading

    Compare how people phrase the question in Search Console with your heading. "Boiler pressure low" and "Why is my boiler losing pressure?" are the same question. Your heading should sound like the person, not the manual.
