What Is Domain Authority?

Domain authority is a third-party score (0–100) estimating how likely a website is to rank, based mainly on its backlink profile.

Domain Authority (DA) is a metric invented by Moz — with equivalents like Ahrefs’ Domain Rating — that scores a website from 0 to 100 based largely on the quantity and quality of sites linking to it. Higher scores correlate with stronger ranking ability.

Google has repeatedly stated it uses no single "domain authority" metric, so DA is best treated as a comparative gauge: useful for sizing up competitors and evaluating link prospects, meaningless as an absolute target.
