Answer engine optimization: how to write pages AI can quote
Kane Vu
Short answer
Answer engine optimization (AEO) is writing web pages so that an answer engine, such as ChatGPT, Gemini, Claude, Perplexity or Google AI Overviews, can lift a direct answer from them. In practice it means headings phrased as the questions buyers ask, an answer of two to four sentences right under each one with real numbers, public prices, one page per service, and structured data that matches the visible text.
What is answer engine optimization?
An answer engine is any system that replies to a question with an answer instead of a list of links. Voice assistants and the featured snippets at the top of Google results were early examples. Today the main answer engines are AI assistants: ChatGPT, Gemini, Claude and Perplexity, and the AI Overviews and AI Mode inside Google Search.
Answer engine optimization, or AEO, is the craft of writing pages those systems can quote. It overlaps almost entirely with generative engine optimization; where GEO covers the whole chain from bot access to identity, AEO is about the last link, the words on the page. The question it asks is simple: when a buyer asks something your business can answer, is the answer written on your site in a form a machine can lift out and repeat?
Many business websites fail that test not because they lack knowledge but because they write around it. The answer to “how much does it cost” is “contact us”. The answer to “how long does it take” is spread over three paragraphs about quality. An assistant looking for a sentence to quote finds nothing to take, and quotes someone who wrote it down.
Why assistants quote answers, not pages
When an AI assistant searches the web to answer a question, it does not read your site the way a visitor does. It fetches a few pages, pulls out the passages that answer the question, and writes a reply from them. Google says its AI features may issue several related searches across subtopics and find more supporting pages while the answer is being written. The unit that matters is the passage, not the page.
That changes what makes a page useful.
- A passage must make sense on its own. “As mentioned above, it depends” cannot be lifted out. “A tankless water heater costs between $1,500 and $4,500 installed, depending on fuel type and the venting required” can (that figure, like every price in the examples of this guide, is illustrative).
- The answer must sit close to the question. A heading that asks the question, followed at once by the answer, is the clearest signal a page can give about which text answers what.
- Specific beats complete. A page that answers one question precisely is more useful than one that touches twenty vaguely.
Research on generative engines points the same way: in a 2023 study of what makes content more visible in AI answers, adding statistics, quotations and cited sources helped, and repeating keywords did not. The details are in our guide to generative engine optimization.
Find the questions your buyers actually ask
AEO starts with the questions, and the best source of questions is not a keyword tool. It is the people who already ask them.
- Your inbox and phone. The questions customers ask before buying, written in their words. Ten emails usually hold most of them.
- Your sales and support staff. Ask them for the five questions they answer every week.
- Reviews, yours and your competitors’. Complaints often reveal what buyers wished they had known: hidden fees, waiting times, what was not included.
- Google’s “People also ask” box for your main service, and the related searches at the bottom of the results page.
- The assistants themselves. Ask ChatGPT or Perplexity what someone should consider before hiring a business like yours. The questions it lists are the ones it expects to be asked.
Group what you find into four kinds, because each needs a different kind of answer.
| Kind of question | Example | What the answer needs |
|---|---|---|
| Cost | How much does a bathroom remodel cost? | A price or range, and what moves it |
| Process and time | How long does a roof replacement take? | Steps and durations in days or weeks |
| Choice | Tankless or tank water heater? | When each one fits, with the deciding numbers |
| Trust | Are you licensed and insured? | The facts, and where to verify them |
Most service businesses end up with 15 to 30 questions worth answering. That is enough for a FAQ section on each service page and a handful of longer pages for the questions that need more than a paragraph.

Write answers that can be lifted
The pattern is the same for every question: the question as a heading, the answer in the first sentence under it, the detail after. The prices in the examples below are illustrative, not market data.
- Answer in the first sentence. “A bathroom remodel in Chicago costs between $15,000 and $35,000 for a full gut renovation” comes before any discussion of what drives the price.
- Two to four sentences for the core answer. Long enough to be complete, short enough to be quoted whole.
- Use real numbers. Prices, durations, sizes, years of warranty, distances. A number is the most quotable thing a page can hold.
- Name things. The town, the product, the standard, the license type. “We serve the area” is useless; “we serve Plano, Frisco and McKinney” is an answer.
- Use the buyer’s words in the heading. “How much does it cost to replace a garage door?” rather than “Pricing information”.
- Keep each answer self-contained. No “see above”, no “as we said”, no pronoun that points to an earlier paragraph.
If the honest answer is “it depends”, say what it depends on, with numbers for the common cases. “Between $8,000 and $12,000 for most single-car garages, more for custom wood doors” is still an answer. “It depends on your needs” is not.
Public prices and one page per service
Two kinds of page carry more of AEO than any FAQ.
A price page, or prices on each service page. “How much does it cost” is among the most common questions buyers ask, and it is the one most business sites refuse to answer. When your site gives no price, an assistant asked about cost has two choices: quote a competitor that does, or quote a national average that may be far from yours. A range with what moves it (“from $2,500 for a standard installation; more for older homes that need a new electrical panel”) gives it something accurate to say about you.
Not every business can publish fixed prices. Most can publish a typical range, a starting price, or the price of the three most common jobs, and explain what changes the figure.
One page per service. A single “Services” page listing everything you do gives an assistant no page to point to when someone asks about one of them. A page for each main service, with what it is, who it is for, how it works, what it costs and the common questions, gives every buyer question a natural home. It also lets each page have a title and a first paragraph about exactly one thing.
Where each answer should live
Once the answers are written, where you put them matters almost as much as how you write them.
- Questions about one service go on that service’s page, in a short questions and answers block near the bottom: cost, time, what is included, what is not. A buyer, or an assistant, reading about drain cleaning finds the drain cleaning answers right there.
- Questions about the business go on the About or Contact page: licenses, insurance, service area, hours, payment methods, who owns the business.
- Questions that need more than a paragraph get a page of their own: “Tankless or tank water heater?” deserves a guide with a comparison table, not three sentences in a FAQ.
- A general FAQ page is the last resort, for the questions that fit nowhere else.
Answer each question in one place only. When two pages on your site answer the same question differently, an assistant has to choose, and it may choose the older one. If a second page needs the answer, link to the first.
Finally, keep the answers current. Prices change, services are added, opening hours move. Put a review of your answer pages on the calendar every few months, and show an updated date on the pages that carry dates, so a reader and a machine can both tell the answer is still true.
Mark up your answers so machines see them
Structured data tells machines in a fixed format what the text on the page already says. Three types matter for AEO.
- FAQPage around a questions and answers section, with each question and its answer exactly as shown on the page.
- Organization or LocalBusiness on the home page, with your name, address, phone, logo and links to your profiles elsewhere.
- Article on guides and posts, with the author and the published and updated dates.
Two facts keep this in proportion. First, Google limited FAQ rich results in August 2023 to well-known, authoritative government and health websites, so for most businesses FAQPage markup no longer produces the expandable questions under a search result. Second, Google says no special schema is needed to appear in its AI features. Markup is still worth adding, because it states your answers and your identity in a form any machine can parse without guessing, but it is a label on the content, not a substitute for it.
The rule that matters most: structured data must match the visible text. Markup that claims answers, prices or reviews the page does not show is a reason for search engines to distrust the page.

A worked example: one FAQ answer, rewritten
Here is a single answer from a service page, before and after. The business and every figure are invented for illustration.
The question: How long does a kitchen remodel take?
Before. “Every kitchen is unique, and our team works closely with you to deliver a result you’ll love. Timelines vary depending on the scope of your project. Contact us to discuss your vision!”
After. “A full kitchen remodel takes 6 to 10 weeks from demolition to final inspection: about a week of demolition, two to three weeks of plumbing, electrical and drywall, and two to four weeks for cabinets, counters and finishes. Custom cabinets add four to eight weeks of lead time before work starts. A cabinet and counter refresh without moving walls or pipes takes 2 to 3 weeks.”
| Before | After | |
|---|---|---|
| Answers the question in the first sentence | No | Yes |
| Numbers a buyer can plan with | None | Five durations |
| Says what changes the answer | “Scope”, unexplained | Custom cabinets, moving walls or pipes |
| Can be quoted without the rest of the page | No | Yes |
The after version takes longer to write, because it forces the business to state what it knows. That is the whole of AEO in one paragraph: knowledge the business already has, written down where a machine and a buyer can both find it.
What the MWY checker looks for in your answers
The MWY checker scores the content layer of your site among its 24 items. For AEO, the items that count are whether each page has a title and description, whether pages have one H1 and clear subheadings (and how many headings are written as questions), whether there is a questions and answers section with FAQPage schema, whether prices appear as text, whether each main service has a page of its own, and whether posts show dates and name their author. It also checks your Organization or LocalBusiness schema and whether your address and phone are written as text.
These are rules applied to the pages it reads, so some items are marked as a signal rather than a certainty: a checker can see that a page has questions and prices, not whether the answers are good. You can see how each item is detected on the methodology page. In Pro, every item that fails comes with the steps for your platform and, for FAQ schema, a template to fill in; Pro also asks ChatGPT, Gemini, Claude and Perplexity 20 buyer questions every week, so you can see which answers name you. See what Pro includes.
The checker does not write your answers, and it does not promise that an assistant will quote them. It shows where your site leaves a buyer’s question without an answer to take.
Questions people ask
What is the difference between AEO and GEO?
They overlap almost entirely. GEO, generative engine optimization, covers everything that decides whether AI can use a site: bot access, identity and content. AEO, answer engine optimization, focuses on the content: questions as headings and short, specific answers an assistant can lift. Good AEO is the content part of GEO.
Is FAQ schema still worth adding?
Yes, with lower expectations. Since August 2023 Google shows FAQ rich results only for well-known government and health sites, and it says no special schema is needed for its AI features. FAQPage markup still states your questions and answers in a form any machine can parse, so it is worth adding where it matches the visible text.
How long should an answer be for AI to quote it?
Put the direct answer in the first sentence and keep the core of it to two to four sentences, with the numbers that matter. That is long enough to be complete and short enough to be lifted whole. Detail, exceptions and examples can follow underneath for readers who want more.
Should I publish prices if every job is different?
Publish what you can: a typical range, a starting price, or the price of your most common jobs, with what moves the figure. Without any price on your site, an assistant asked about cost can only quote a competitor or a national average, which may be far from what you charge.
Where do I find the questions customers ask before buying?
Start with your own inbox, phone notes and sales staff: the questions people ask before buying, in their words. Add your reviews and competitors’ reviews, Google’s People also ask box for your main service, and what an assistant says someone should consider before hiring a business like yours.
