What is Domain Authority (DA)?

Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how likely a website is to rank on search engine result pages (SERPs). Scores range from 1 to 100, with higher scores corresponding to a greater ability to rank.

DA vs. DR vs. AS

• DA (Moz): Focuses on the predictive ranking power based on links.
• DR (Ahrefs): “Domain Rating” measures the strength of a target website’s backlink profile.
• AS (Semrush): “Authority Score” uses traffic data + backlinks to give a holistic score.

How to Improve Your Score

Authority scores are logarithmic. It is easier to grow from 10 to 20 than it is from 70 to 80. The best way to improve is by acquiring high-quality backlinks from reputable sites in your niche and removing toxic spam links.
