The Domain Authority (DA) is a score created by Moz based on several factors, including the root domains that link to a site, the total number of (external) links, and others non-disclosed.
Moz created the metric to help businesses determine where they may rank on search engine results pages (SERPs).
Ubersuggest is one of the few authorized to use the same metric. That’s because we use Moz’s API to collect backlinks.
