How it works
Type the question a buyer would ask an AI assistant, and add your page if you want it checked.
An AI model breaks the question into the 6 to 10 narrower searches a careful answer would need.
You get the list, each marked answered, partly answered or not covered by your page, with the heading that answers it.
What query fan-out means
When you ask an AI search engine a question, it doesn't run one search for your exact words. It splits the question into several smaller ones and searches for each: what the thing is, what it costs, how the options compare, who each one suits. Then it writes one answer from everything those searches found. That splitting is called query fan-out.
Google has described this openly: it says AI Mode and AI Overviews may run multiple related searches across subtopics to build a response, and OpenAI says ChatGPT search rewrites a prompt into one or more targeted searches. Neither publishes the searches themselves or how many they run for a given question.
For anyone who wants to be cited, this changes the target. Ranking for the main question isn't enough. The answer gets built from whichever pages answer the follow-up questions, so a page that covers them clearly has more chances to be quoted.
How to read the results
Each line is one follow-up search, labelled with its angle: what it is, cost, comparison, who it suits, features, trust, alternatives or how to. Some questions don't need every angle, so the list skips the ones that don't apply.
If you added a page, each follow-up is marked Answered (a heading or passage answers it directly), Partly (it's touched on without a direct answer) or Not covered. We show the heading or a short quote from your page as evidence, and we check that the heading and quote really appear on the page, so an "Answered" with nothing to show for it is downgraded to "Partly".
Copy the list or download it as a CSV to use as a checklist for your next edit.
What to do with the gaps
- Most gaps belong as a short section on the page you already have, not a new page. A clear 40 to 80 word answer under a heading that says what it answers is usually enough.
- Put the direct answer first, then the detail. AI answers quote passages that make sense on their own.
- Some follow-ups, like reviews of your brand or "best X" comparisons, are answered from other sites. Your own page rarely wins those; being mentioned on the sites that rank for them does.
- Don't make a page for every follow-up. Google's spam policies count lots of thin pages made mainly to rank as scaled content abuse.
Judge the work by results, not by how many questions now have a heading: check again in a few weeks whether the AI answers to the main question cite or mention you.
Limits worth knowing
The follow-up questions are a model's prediction of what a careful answer needs, not the real searches an engine ran. Real fan-out changes from one run to the next and between engines. Coverage is judged by a model reading your page's headings and the first part of its text, so long pages may have answers further down that it didn't see, and it reads the HTML before JavaScript runs.
Questions people ask
Are these the exact searches ChatGPT or Google runs?
No. The engines don't publish them, and they change from run to run. These are the follow-ups a careful answer would most likely need, predicted by an AI model. Use them as a checklist.
How is this different from People Also Ask?
People Also Ask shows questions real searchers typed that Google relates to yours. Fan-out is about the narrower searches an AI engine runs to build one answer. They overlap, and both are worth covering.
Should I write a new page for each follow-up question?
Usually not. Most belong as a section on an existing page. A new page makes sense only when a follow-up has its own distinct search results and reader, like a full comparison of two products.
Why does my page show "Partly" when I think it answers the question?
"Partly" means the topic is there but no passage answers it directly, or the checker couldn't find a heading or quote to prove it. A direct sentence under a clear heading usually turns it into "Answered".
Is this query fan-out tool free?
Yes, with no signup and five checks a day. It uses an AI model for each check, so it's open in the countries where RomeoSEO is available.

Romeo fills the gaps AI looks for
He maps the follow-up questions behind your buyers' questions to the pages that should answer them, writes the missing sections, adds the internal links, and sends each change for you to approve.
