Query Fan-Out Simulator

See how AI search engines decompose your keyword and check your content coverage

Free tool

Simulate AI query fan-out

Takes ~10 seconds

Decomposes your keyword into 8-12 sub-queries and checks your sitemap for coverage.

What you get

Generative engine optimization has to account for how AI search actually works: not one lookup, but a keyword decomposed into 8 to 12 sub-queries spanning definitional, comparative, how-to, pricing and alternatives intent. Content that covers only the head term loses the rest to competitors. This simulator shows which sub-queries your page already answers and where the gaps sit.

  • See the exact sub-queries AI engines generate for your keyword with intent classification.
  • Identify content gaps where competitors will be cited instead of your site.
  • Get a coverage score showing what percentage of AI sub-queries your sitemap addresses.

How it works

  1. Enter a target keyword and your domain URL.

  2. The simulator fetches your sitemap, decomposes the keyword into 8-12 AI sub-queries, and matches each against your pages.

  3. Review per-query coverage results with matched URLs and identify content gaps to fill.

Who it's for

  • Content strategists identifying which sub-topics to cover for a target keyword.
  • SEO teams auditing topical coverage against AI search decomposition patterns.
  • AEO strategists prioritising new content creation based on AI query coverage gaps.

What is query fan-out?

Query fan-out is the process AI search engines use to break a single query into multiple sub-queries. For example, 'best CRM software' might fan out into sub-queries about pricing, features, comparisons, reviews, and use cases. AI engines gather answers to all sub-queries before synthesising a response.

How does this tool work?

It fetches your sitemap to build a page inventory, then uses AI to generate realistic sub-queries for your keyword. Each sub-query is matched against your pages to determine coverage. The coverage score reflects what percentage of sub-queries your site can answer.

Why does content coverage matter for AI visibility?

AI engines cite sources that cover the most sub-queries. If your competitor covers 10/12 sub-queries and you cover 4/12, the AI will predominantly cite your competitor. Filling content gaps directly increases your AI citation share.

What's a good coverage score?

75%+ (grade B or A) indicates strong topical coverage. Most sites score 30-50% on first check. Focus on creating content for uncovered 'definitional' and 'how-to' sub-queries first. These are cited most frequently.

Does this need a sitemap?

Yes, the tool requires a publicly accessible sitemap.xml or sitemap_index.xml. Without a sitemap, it cannot determine which pages your site has. Most CMS platforms generate sitemaps automatically.
