What is Query Fan Out?

When you search in Google AI Mode, ChatGPT, Gemini or Perplexity, the AI doesn't just look up your exact question. It decomposes your query into 8–12 specialized sub-queries, fetches information for each one, and merges everything into a single answer. This process is called Query Fan Out.

Research shows that Gemini 3 generates an average of 10.7 sub-queries per prompt — 5x more than ChatGPT. 95% of these sub-queries have zero traditional search volume, making them invisible to standard keyword tools.

Why This Matters for Your Content

Your page might rank #1 for the original query, but if it doesn't answer the fan-out sub-queries — the ones the AI actually uses to research its answer — you're invisible to AI-mediated search. 68% of pages cited in AI Overviews are NOT in the top 10 organic results.

This tool simulates the fan-out process and shows you real Google results for each sub-query, so you can identify content gaps and optimize for AI citability.

How does this tool work?+

The tool uses GPT-4.1 to simulate how AI search engines decompose your query into sub-queries, matching real-world fan-out patterns from Gemini, ChatGPT and Perplexity. Then it fetches actual Google SERP results for each sub-query via DataForSEO to show you who currently ranks.

What is citability?+

Citability (0–100) estimates how likely an AI search engine is to cite external sources for a given sub-query. Factual queries with clear answers (e.g. product specifications) have high citability. Subjective or common knowledge queries have lower citability.

How accurate are the sub-queries?+

The sub-queries are AI-simulated, not captured from live Gemini/ChatGPT sessions. They represent realistic fan-out patterns based on research showing typical decomposition strategies. The real SERP data for each sub-query is live from Google.

What's the daily limit?+

10 free analyses per day. Each analysis uses 1 AI credit plus SERP credits for sub-query lookups. For unlimited access, enter your own OpenAI and DataForSEO API keys in Settings.

Can I analyze queries in different languages?+

Yes. Select your target country and language. The AI generates sub-queries in the appropriate language and the SERP results reflect local Google rankings for that market.
