What is Query Fan Out and How it Works [2025]

Query fan-out is an AI search technique that breaks a problem into multiple related sub-topics. This helps gather information from different sources and provides practical, actionable solutions.

For example, if you searched on Google or an AI platform “How to lose weight in 60 days,” it could generate some actionable sub-topics about dietary changes, exercise routines, lifestyle adjustments, and important health considerations.

Each sub-query gives practical advice you can follow step by step. This method allows the AI to give richer, more relevant answers. It delivers a complete, well-rounded plan instead of just a single tip.

How Query Fan Out Works

Now I am going to explain my personal experience step-by-step with a query fan out regarding how it works.

1. Understand the Problem: When I search the query on Google “How to lose weight in 60 days” The AI overview sees that I want to lose weight and understands my goal is to achieve it in 60 days. It identifies key areas like diet, exercise, and lifestyle that matter for this goal.

My advice: Focus on solving real problems in your content so that AI can understand your content is not generic, but solves specific problems.

2. Break It Down: Then, AI overview split my goal into smaller parts, such as healthy eating (for diet), workout routines (for exercise), sleep, and stress management (for healthy lifestyle). This ensures all important factors are covered.

My advice: Build Topical Authority to cover all aspects in your content

3. Create Sub-Queries: Each part becomes its own query for AI overview , like “best diet for weight loss,” “effective 60-day workout plan,” or “sleep tips for fat loss.” The AI digs into each aspect.

My advice: Create more relevant content that you can internal links with each other

4. Search Everywhere: These sub-queries run across multiple sources like websites, databases, and AI knowledge graphs. Get information from different perspectives.

My advice: That’s why SEWO is important

5. Collect the Info: The AI gathers the best advice, tips, and strategies from all the sources. Only the most relevant and practical suggestions are kept.

My advice: EEAT is important to prioritize your content over others, and statistics, proof, reviews, structure are also important here to beat the competition.

6. Combine & Deliver: Finally, it puts everything together into one clear plan I can follow. Now I get a complete, actionable 60-day weight loss strategy instead of scattered tips.

My advice: As i solved my weight lose problem through Ai overviews or from your content , you need to track performance in Google Analytics 4 and user behavior so that you can produce more content to solve more relevenat problems.
