DomainRating.org launches a free domain authority checker built on the open web

DomainRating.org has joined the Website Holding portfolio as a free domain authority checker anyone can use without creating an account.

Most domain authority tools compute their score from a proprietary, closed backlink index, so two checkers rarely agree and nobody outside the company can see how the number was reached. DomainRating.org takes a different approach: its Open Authority Rank is computed from Common Crawl's public web graph, an open, freely downloadable snapshot of the web that anyone can inspect. A domain gets a score from 0 to 100, or an honest null when the data is not yet sufficient to compute one, rather than a guessed number.

Visitors can look up any domain for free, track a personal watchlist of domains to follow, and verify ownership of a domain to add a checkmark and an embeddable rating badge to their own site. Domain owners can also compare two domains side by side to see how their authority stacks up.

The scoring engine reruns on a weekly Common Crawl release, so ratings reflect the current state of the web rather than a stale snapshot. Read more about the methodology and try a lookup at domainrating.org.
