Domain Authority
A third-party score (commonly from Ahrefs or Moz) estimating how likely a domain is to rank in search results, based largely on its backlink profile.
Domain Authority is not a Google ranking factor — it is a third-party estimate, most often produced by Ahrefs (as Domain Rating) or Moz. It is a useful proxy for a domain's backlink strength and general search visibility potential, but it should never be read as a guarantee of rankings or traffic.
For pre-revenue domain acquisitions, Domain Authority is one of the few objective signals available before real content and traffic exist, which is why it appears prominently on early-stage listings.
