Domain Rating by Ahrefs · DR is scored 0–100 on a logarithmic scale.
How to read the score
Scores come from Ahrefs Domain Rating (DR), which measures the strength of a site's backlink profile relative to every other site in Ahrefs' index. It is comparable to, but not the same as, Moz Domain Authority (DA).

Check Domain Authority in Bulk
Paste up to 20 domains or URLs to see how strong each site's backlink profile is. Scores come from Ahrefs Domain Rating (DR), which rates every site from 0 to 100 compared with all the other sites in the Ahrefs index.
How to Use the Score
- Benchmark competitors: check the sites ranking on page one for your keywords next to your own
- Vet link prospects: compare guest-post and outreach targets before you pitch them
- Track progress: recheck your domain as you earn new links
Domain Rating vs Domain Authority
Ahrefs Domain Rating and Moz Domain Authority both estimate backlink strength on a 0 to 100 scale, but they use different link indexes and formulas, so the same site gets different numbers. Compare sites using one metric only.
