Mastering Domain Rating (DR) and URL Rating (UR) in Link Building
In modern search engine optimization, evaluating backlink authority is essential for competitor benchmarking, expired domain acquisition, and guest post outreach. Ahrefs Domain Rating measures the quantity and quality of unique linking root domains pointing to a site, weighted by their own authority.
DR
Domain Rating
Logarithmic 0-100 score indicating overall site-wide backlink equity. Moving from DR 70 to 80 requires exponentially more links than DR 20 to 30.
UR
URL Rating
Evaluates page-specific backlink authority and internal link equity passing into a specific destination article.
RD
Referring Domains
The count of unique IP subnets and distinct domain entities linking to the target. Higher diversity directly correlates with rank stability.
