What is answer engine optimization (AEO)?

Where AEO came from

The idea predates chatbots. Google's featured snippets flip the usual result, showing a descriptive answer first and the link second, and they also appear inside the related questions box known as People Also Ask. Site owners noticed that a page phrased as a clear answer could win that top spot, and AEO became the name for writing that way.

Google's documentation for featured snippets only explains how to opt out of them, using nosnippet, data-nosnippet or max-snippet. It lists no tag that requests one; Google chooses the passage itself.

AEO now covers AI answers too

AI Overviews and AI Mode in Google, and assistants such as ChatGPT, are answer engines as well, and they tend to appear on exactly the questions AEO targets. In a Pew Research Center study of real Google searches from March 2025, 60% of queries that began with who, what, when or why produced an AI summary, compared with 8% of one- or two-word searches.

Google's position is that this is still SEO. Its guide to generative AI features, last updated in July 2026, says that, from Google's perspective, AEO and GEO work is optimizing for search, and that no special files or markup are needed.

What changed with FAQ markup

For years, AEO advice meant adding FAQ structured data to earn expanded results. In August 2023 Google limited FAQ rich results to well-known, authoritative government and health websites, so most businesses no longer get them. A visible FAQ section is still useful to readers, and if you keep the markup, Google's rule is that structured data must match the visible text on the page.

Which questions to answer first

You already know them. They are the questions your office hears on the phone every week: how much, how long, do you serve my town, do you handle insurance claims, what happens if it rains on install day. Write those down before you look at any tool.

Then check Search Console's Performance report and filter the queries for words like how, what, cost and near. Those are the searches already showing your site. A page that answers them clearly gives Google and AI assistants something precise to quote, and gives the customer a reason to trust you before they call.

How to write an answer-first page

The format is simple, and it works for people as well as machines:

• Use the customer's question as a heading, in their words, for example How much does a new roof cost in Grand Rapids?
• Answer it in the first sentence or two, so the answer still makes sense if it is quoted on its own.
• Follow with what changes the answer: sizes, materials, access, permits, exceptions.
• Use real specifics such as the ranges you charge, the materials you install, the towns you serve and your license number.
• Close with a clear next step, because a reader who got the quick answer still needs a reason to call you.

What AEO cannot do

It cannot force an answer box or an AI citation. Google says a page that meets every requirement may still not be crawled, indexed or served. And a quoted answer does not always bring a visit: Pew found that searchers who saw an AI summary clicked a traditional result in 8% of visits, compared with 15% when no summary appeared.

So AEO for a local business has two jobs: be the source the answer draws on, and make the next step obvious for the people who do click through. Modern Apex writes service pages this way, with the direct answer first and the phone number close behind.
