A third-party search ranking metric (Moz scale 1-100) predicting a domain's likelihood to rank in search results, based on quality and quantity of inbound backlinks. Used in affiliate publisher evaluation: Tier 1/2 content publishers should typically meet DA 30+ threshold for competitive category ranking potential. Not an official Google metric — correlates with ranking ability but is one of many ranking factors. Similar metrics: Ahrefs Domain Rating (DR), SEMrush Authority Score.
