Domain Authority (DA)

Moz's 0–100 score predicting how likely a website is to rank in search results, based mainly on its link profile.

Domain Authority (DA) is Moz's equivalent of Ahrefs' Domain Rating: a 0–100 predictive score of a site's ranking potential, driven largely by the strength of its backlink profile.

Like DR, DA is a third-party estimate rather than an official Google signal, and it is best used comparatively — to benchmark your site against competitors or to gauge the relative value of a link source.
