Data Source

Where this data comes from

All rank data comes from Common Crawl's Web Graph — a nonprofit that crawls billions of web pages and publishes the data openly. AI models like ChatGPT, Claude, and Gemini use this data for training.

This tool does not connect to Google, Bing, or any search engine. All lookups are performed against the locally hosted database on this server.

Data coverage: This online tool uses Common Crawl's latest domain-level Web Graph — the April–June 2026 release (cc-main-2026-apr-may-jun), covering 121.1 million domains. Common Crawl publishes a new web graph every one to two months, and this database is refreshed to track the latest release.

Desktop app: The free desktop version is Tom's Link Authority, which runs the same April–June 2026 release as this online tool plus offline backlink analysis.
