What does this checker show?
Authority scores are third-party estimates of how strong a domain’s backlink profile is. Domain Authority (DA) is Moz’s score and Domain Rating (DR) is Ahrefs’ score; both run from 0 to 100.
For websites in our marketplace this tool shows the DA, DR and traffic figures we have verified, with the source and date. For any other domain it shows Open PageRank (when enabled) and direct links to the official Moz and Ahrefs checkers, so you always see a real number rather than a guess.
How to use authority scores
- Compare sites within the same niche, not across niches
- Combine with relevance and real traffic — a relevant DA 25 site can beat an unrelated DA 70
- Re-check periodically: scores change as the web changes
Frequently asked questions
Is Domain Authority a Google ranking factor?
No. DA and DR are third-party estimates. Google does not use them, but they are a useful shorthand for comparing link profiles.
Why don’t you calculate DA yourselves?
DA and DR are proprietary to Moz and Ahrefs. Showing an invented number would be misleading, so we show verified data or link to the official tools.
