Domain Ranking and Domain Authority are both scores that got developed to rank websites and to give an indication of a website’s quality and power. Domain Ranking (DR) is an element created by Ahrefs for ranking websites. The ranking is based on a website’s backlink profile and uses a scale of 0 to 100. Domain Authority (DA) is an element created by Moz for ranking that predicts the ranking of websites on search engines. Overall, both scores are used to rank the quality and authority of websites.
