FAQ

The score is our own open-data metric (0-100) and is not Moz Domain Authority or Ahrefs Domain Rating.
How many backlinks does ca.gov have?
ca.gov is linked to from 186,640 other domains in the Common Crawl web graph (release cc-main-2026-jul-aug-sep). This counts referring domains, not individual backlinks, and Common Crawl does not see the whole web, so commercial tools that crawl more will show larger numbers.
How does ca.gov rank among all websites?

Is the ca.gov authority score the same as Moz DA or Ahrefs DR?
No. It is an independent score computed from open data (Common Crawl, Majestic Million, Chrome UX Report). It is consistent across all domains, so it works for comparing and filtering sites, but the numbers will not match the commercial tools.
