Query fan-out planner
Google says AI Overviews and AI Mode use query fan-out, issuing several related searches for one question. This planner suggests likely sub-questions for a topic using fixed templates, so you can check whether your content covers them. It does not show Google's real fan-out queries, which are not public.
What fan-out is
Google defines query fan-out as “a set of concurrent, related queries generated by the model” and gives an example: a question about lawn weeds may trigger searches for herbicides, chemical-free removal and prevention.[1] AI Mode breaks questions “into subtopics.”[2] ChatGPT also rewrites prompts into one or more targeted searches.[3]
How to use the output
- Mark which sub-questions your site already answers well.
- Answer missing ones inside the most relevant existing page, or create a page only when the subtopic deserves one.
- Check real demand in Search Console queries and your prompt panel.
Don’t create a thin page for every variation: Google says that is scaled content abuse.[1] Vendor-documented
Worked example from Google’s documentation
Google’s guide gives one seed query and three fan-out queries.[1] Vendor-documented Mapping them shows how one page can cover a cluster. The three queries are Google’s; the page layout is our illustration.
| Fan-out query (Google’s example) | What the reader needs | Where to answer it |
|---|---|---|
| best herbicides for lawns | Chemical options and when each applies | H2 “Chemical options” on one lawn-weeds guide |
| remove weeds without chemicals | Manual and non-chemical methods | H2 “Removing weeds without chemicals”, same guide |
| how to prevent weeds in lawn | Ongoing prevention | H2 “Preventing weeds”, same guide |
The seed query was “how to fix a lawn that’s full of weeds.” One guide with three headed sections serves all three sub-queries.
Section, new page, or skip?
| If the sub-question… | Do this | Basis |
|---|---|---|
| Serves the same reader and task, and fits in a few paragraphs | Add a section to the existing page | Our reading of Google’s advice to organize pages with clear headings[1] |
| Needs its own depth for a different task, product or place, and would still help visitors if search did not exist | Give it its own page | Google: focus on what your visitors would find helpful and satisfying[1] |
| Only rewords another question | Skip it | Google says its AI systems understand synonyms and general meanings, so you need not capture every variation[1] |
Creating separate pages for variations primarily to manipulate rankings or AI responses violates Google’s scaled content abuse policy.[1][4] Vendor-documented
Frequently asked questions
Does this show Google's actual fan-out queries?
No. Those aren't public. The planner uses fixed templates for common question patterns.
Where can I see real sub-queries?
Search Console query data and Bing's AI Performance report (sample grounding queries) are the closest first-party sources.
