Website Authority Checker - Free Ahrefs Tools Ahrefs Website Authority Checker is a free SEO tool that helps you measure the overall strength of a website based on its backlink profile. This concept is often called “website authority” or “domain authority,” but it should not be confused with Moz’s Domain Authority (DA) metric.
At Ahrefs, website authority is measured using a metric called Domain Rating (DR). Domain Rating runs on a scale from 0 to 100. A higher score means a stronger backlink profile and, in general, a more authoritative domain.
Website authority is an SEO concept that describes how strong a domain is compared to others on the web. It reflects how many websites link to a domain and how strong those linking websites are.
Although Google says it does not use “domain authority” as a direct ranking factor, backlink strength plays a major role in rankings. For this reason, authority metrics like Ahrefs’ Domain Rating are useful indicators when analyzing SEO competitiveness.
Ahrefs calculates Domain Rating by analyzing:
How many unique websites link to a domain
How authoritative those linking domains are
How many other sites those domains link to
The tool focuses only on backlinks. It does not consider traffic, content quality, domain age, or spam signals.
Website authority helps you:
Compare your site against competitors
Understand how difficult it may be to rank in your niche
Evaluate link opportunities
A “good” authority score is always relative. Your score is strong if it is similar to or higher than other sites in your industry.
This tool is useful for:
Benchmarking competitors within the same niche
Vetting link prospects before building backlinks
Website authority should never be the only metric you rely on. Always combine it with relevance, content quality, and real traffic data.
(In the future, you may also want to compare this with a Moz Domain Authority checker for a broader perspective.)
