Definition: Domain Rating (DR) is a proprietary SEO metric developed by Ahrefs that measures the strength and authority of a website’s backlink profile on a logarithmic scale from 0 to 100. A higher DR indicates a larger volume of high-quality inbound links from authoritative sites. DR is used as a comparative benchmark for assessing how competitive a domain is in terms of link authority relative to other sites.
Why It Matters: DR provides a quick, standardised way to compare the link authority of different websites — your own domain against competitors, or potential link partners against each other. It helps SEO teams set realistic ranking expectations (pages on higher-DR domains tend to rank more easily for competitive keywords), evaluate the value of potential backlinks (links from high-DR sites carry more weight), and track the growth of a site’s own authority over time. Because DR is specific to Ahrefs, it should be understood alongside other authority metrics — Moz’s Domain Authority (DA) and Semrush’s Authority Score are equivalent measures from competing tools, each using their own methodology.
How It Works: Ahrefs calculates DR by analysing the number of unique websites linking to a domain, the DR of those linking domains, and the number of outbound links each linking domain has (as a dilution factor). The score is logarithmic — moving from DR 70 to DR 80 requires substantially more link acquisition than moving from DR 20 to DR 30. DR is visible in the Ahrefs Site Explorer tool for any domain. It updates roughly every 30 days as Ahrefs recrawls the web. DR is a backlink-specific metric and does not account for content quality, technical health, or traffic — it should be used alongside other signals, not as a standalone measure of SEO performance.
