A new DataForSEO study of 100,000 ChatGPT prompts found that 47% of them trigger fan-out queries: hidden searches ChatGPT runs against the web before it answers. If your content does not match those hidden queries, you do not get cited. Here is how to find them and write content that does.
Why is there a "search you will never see" deciding if ChatGPT recommends you?
Because ChatGPT does not just take your question and go fetch an answer. It rewrites your question into multiple secondary questions, runs those against the web, then synthesizes the response. Those rewritten questions are called fan-out queries, and a DataForSEO study of 100,000 ChatGPT prompts found 47% of prompts trigger them.
Translation: the most important search query about your business is one no human ever typed. If your page does not answer that hidden query, ChatGPT skips you, even if you rank for the obvious keyword.
What are fan-out queries, exactly?
Fan-out queries are the secondary questions ChatGPT generates from your original prompt and runs against the web before answering you. They are the AI's way of saying "your query is not specific enough, let me search smarter."
Say a user types "best Italian restaurants in Chicago". ChatGPT might fan that out into:
- best Italian restaurants in Chicago reviews
- top Italian restaurant Chicago price
- popular Italian restaurants Chicago menu
Each of those is a real search query running silently behind the scenes. The pages that match those fan-outs are the pages ChatGPT cites and recommends. This is the mechanic behind every modern AI search engine, and it is the core of generative engine optimization.
Why does matching fan-out queries equal citations?
Because citations are awarded to pages that answer the AI's hidden questions, not the user's original one. ChatGPT, Perplexity, and Google's AI Overviews all rely on fan-out style retrieval. Match the fan-out, get the citation. Miss it, get ignored.
This is why a page can rank #1 in classic Google and still never appear in ChatGPT search. The traditional "head term" mindset does not survive in AI search. You have to think in clusters of sub-questions, which is exactly what the capsule content method was built for.
Community win: William Moon, a financial advisor in Arizona, took his CTR from 0.3% to 2.3% by rewriting his pages to answer fan-out style sub-questions, then closed a $165,000 deal off one AI-driven lead.
How do you find the fan-out queries running for your niche?
You need a fan-out dataset. The fastest way is a free tool called DataWise, which pulls fan-out queries from DataForSEO's index and gives you 5 free uses on signup.
The flow inside DataWise:
- Sign up free, land on the dashboard (your Google Search Console connection is optional).
- Go to Keyword Research and pick the Fan-Out Queries tab.
- Drop in your seed keyword, for example "local SEO", and hit Explore.
- DataWise returns the fan-out queries triggered for that seed, plus AI search volume and trends.
- Filter to only fan-out queries (you can skip "people also ask" and FAQs, which are different beasts).
- Export the ones that make sense for you to a CSV. That is your content plan.
Heads up: as of recording, fan-out data is US-English only. The dataset is brand new, so expect international expansion soon.
If you are technical, you can also wire DataForSEO directly into Claude Code and run fan-out research from your terminal. I walk through that setup in this video.
Which fan-out queries should you actually answer?
Pick the ones that match your service, your audience, and your buyer intent. Not every fan-out is worth answering, and AI search volume is not the only signal. If a fan-out query makes sense for your business and the question is clearly being asked by ChatGPT, that is enough reason to write the page.
Quick triage rules:
- Definitions: "what is X and how does it work" usually deserves a pillar post.
- Verticals: "X for lawyers / dentists / agencies" become dedicated niche playbooks.
- Comparisons: "X vs Y" or "is X worth it" map to comparison posts that AI loves to cite.
- Process: "how to rank in Map Pack" become tactical how-to articles.
You do not need to answer all 99 fan-outs DataWise returns. Pick the 8 to 12 that fit your offer and start there.
How do you write content that actually gets cited?
You answer the fan-out query directly, in the first sentence of the section, then expand. AI engines are looking for self-contained, extractable answers, not 1,500 words of warm-up before you say anything useful.
The repeatable structure that works in 2026:
- TL;DR or summary box at the top, 40 to 60 words, covering the whole article.
- Every H2 phrased as a question that maps to a fan-out query.
- Direct answer in the first 1 to 2 sentences of every section, then context.
- Schema markup (Article, FAQ, HowTo) so engines can parse it cleanly.
- Linked sources for every stat claim, because AI engines weight cited content higher.
This is the capsule content method in one paragraph. It is also exactly how this post is structured. If you want the full writing checklist, grab the free blog post optimization checklist here.
Frequently Asked Questions
What is a fan-out query in ChatGPT?
A fan-out query is a secondary question ChatGPT generates from your original prompt and silently runs against the web before answering. It is how the model gathers enough source material to give a confident response. The DataForSEO 100,000-prompt study found 47% of ChatGPT prompts trigger fan-outs.
How is a fan-out query different from "people also ask"?
People also ask is a Google SERP feature populated from real human searches. Fan-out queries are AI-generated rewrites that no human ever typed, used internally by ChatGPT and other LLMs to retrieve sources. Some overlap exists, but fan-outs are uniquely a generative engine optimization (GEO) signal.
Do fan-out queries work outside the United States?
Not yet. As of April 2026, the DataForSEO fan-out dataset only covers US-English queries. International coverage is expected to roll out as the dataset matures.
Can I find fan-out queries for free?
Yes. DataWise gives you 5 free fan-out lookups when you sign up, no credit card. After that you can either upgrade or join AI Ranking School for unlimited access.
Will ChatGPT cite my page if I just stuff fan-out keywords in?
No, and this is where most people screw it up. You have to genuinely answer each fan-out query in a self-contained section with a direct opening answer, supporting context, and ideally a linked source. Keyword stuffing reads as spam to LLMs the same way it does to Google.
Want unlimited fan-out research and the playbook?
DataWise is free to try with 5 lookups. If you want unlimited fan-out queries, the full content writing system, weekly tutorials, and a community of operators implementing this every week, join AI Ranking School. That is where members like William, Tim Armstrong, and Steven (800+ pages, 105 appointments/month) are running this play.
