FAQ

What is the domain authority of hud.gov?
hud.gov has a domain authority score of 67 out of 100 (above average for a business website), based on 43,735 referring domains and a web graph rank of 6,322 among 133 million domains; its traffic rank is Top 100K websites (Chrome). The score is our own open-data metric (0-100) and is not Moz Domain Authority or Ahrefs Domain Rating.
How many backlinks does hud.gov have?
hud.gov is linked to from 43,735 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 hud.gov rank among all websites?
Its web graph rank (harmonic centrality) is 6,322 out of 133,241,980 ranked domains, which puts it in the top 0.01%. Its PageRank position is 2,084. Majestic Million ranks it #1,798.
Is the hud.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.
