Answer engine optimization (AEO) is the page-level work of making your content the thing an assistant quotes when it answers a question. Where generative engine optimization is the strategy, AEO is the checklist you run on a single page before you publish it.
This is the checklist we use. Each item has a reason behind it, drawn from what ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews actually cited when we asked them buyer questions on 2026-10-20, and from what the providers say in their own documentation.
We make Seen42, an AI visibility tool, so read our product notes with that in mind. Everything else in this guide works without it.
1. One page answers one question
Assistants pull a passage that answers the question in front of them. A page that answers "which [category] tool is best for a small team" in one section and "how to migrate from [competitor]" in another will be half-relevant to both. Give each buyer question its own URL, and make the title the question or its direct answer.
2. The answer is in the first three sentences
Open with the answer, with names in it. "For a ten person agency, the three payroll tools worth comparing are A, B and C; A is cheapest, C handles contractors best" is quotable. "In today's fast-moving business environment, payroll matters more than ever" is not, and it pushes the quotable part below the fold. Background, context and disclosure come after the answer, not before.
3. Every section stands alone
An assistant often lifts one section, not the whole page. Start each section with a sentence that still makes sense on its own: name the product or the claim rather than starting with "it" or "this". Keep headings descriptive and in sentence case, and let them answer their own question early.
4. Specific facts, with dates and sources
The one controlled study of generative engines found that adding citations, quotations and statistics improved a page's visibility in answers by 30 to 40 percent, while sounding authoritative did nothing. Write the price, the limit, the integration, the date you checked it, and link the source. Replace "affordable" with the number. Replace "many businesses" with the count, or cut the sentence.
5. A table where the question is a comparison
For "X vs Y" and "best X for Y" questions, assistants reproduce tables readily. Use the same criteria for every row, put restrictions in the cell rather than in a footnote, and keep the table readable on a phone. Say what each column means next to the table.
6. Say who the page is for, and who it is not for
Buyer prompts carry constraints: team size, budget, country, platform. An honest "if you have more than 50 people, look at X instead" is exactly the kind of sentence an assistant quotes when the user's question includes that constraint. It also keeps the page credible with the human reading it.
7. Visible FAQ, in the buyer's words
Add three to five questions phrased the way people type them, each answered in two to four standalone sentences. Keep them on the page as visible text. Google's documentation says FAQ rich results are no longer shown in Search as of May 2026, so do not add FAQ markup expecting a search feature. Add it, if you add it, because the questions and answers are real content that matches what is on the page. Google's AI features guidance asks that structured data match the visible text.
8. Crawlable, in plain HTML
The page must be reachable by OAI-SearchBot (ChatGPT search), PerplexityBot, Claude-SearchBot and Googlebot. Check robots.txt, your CDN and firewall rules, and that the main content is in the HTML rather than loaded by a script after the fact. Our AI crawler guide lists each bot and what blocking it does.
9. The technical basics
A canonical URL, an entry in the sitemap, HTTPS, a sensible page title and description, and internal links from pages that already get traffic. None of this is new. Google says there are no additional requirements to appear in AI Overviews beyond what Search already needs.
10. A visible date, and a reason to update it
Three of the five assistants we asked about Perplexity citations mentioned freshness. Show when the page was last reviewed, and review it when a price or a fact changes. A comparison page with last year's prices is a liability in an answer, because the assistant will quote the wrong number with your name next to it.
11. The same facts everywhere
Assistants cross-check. If your pricing page says one thing and your G2 profile, your Google Business Profile and a partner directory say another, you have given the assistant a reason to prefer a competitor whose facts agree. Keep one list of facts about your business and reuse it.
12. Measure the prompt the page was built for
Write down the prompt the page is meant to answer before you publish, ask the assistants weekly, and record whether you are named and whether the new page is cited. Keep a few prompts you did not build pages for as controls, so a general shift in the assistants does not get mistaken for your result. Our guide to measuring AI visibility covers the method.
What to leave out
Leave out invented statistics, testimonials you cannot attribute, and claims about competitors you did not check on their own pages. Leave out keyword repetition; the study above found it made things slightly worse on Perplexity. Leave out a 400-word introduction. The assistant will not read past it, and neither will the buyer.
Where Seen42 fits
Seen42 checks the prompts your buyers ask on ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews, shows who is named and cited instead of you, and builds and hosts comparison, facts and guide pages from your own facts. Paid plans start at $39 a month for 15 prompts; the Free plan checks 10 prompts once on ChatGPT and Gemini. Its comparison, facts and guide pages are built to this checklist: answer first, a table where it helps, a visible FAQ, competitor details from the competitor's own page with the date checked, and a claim check that holds back publishing until every claim traces to one of your facts or a source.
