Off-Page SEO

Domain Authority

Domain authority is a third-party score, on a 1 to 100 scale, that predicts how likely a domain is to rank, based largely on its backlink profile.

It is useful for comparing sites against each other, but it is not a Google metric and Google does not use it to rank you. Treat it as a directional benchmark rather than a target to optimise directly. The popular versions come from tools like Moz and Ahrefs.
