Website Authority Checker
Free tool to check the "authority" of any website based on the quality and quantity of its external backlinks.
About Website Authority Checker
Website Authority Checker is a free tool from Ahrefs that calculates a domain's Domain Rating (DR), a metric scored on a 0-100 scale reflecting the strength of a website's backlink profile. Users enter a domain to see its DR score, calculated based on the number and quality of unique referring domains linking to that site.
The tool is aimed at SEO practitioners and marketers evaluating a website's link-based authority, whether for their own site or competitors. Ahrefs also offers a Domain Rating API for pulling DR data programmatically across multiple domains, and a browser extension (Ahrefs SEO Toolbar, available for Chrome and Firefox) that surfaces DR and URL Rating (UR) metrics while browsing, requiring a free Ahrefs account.
