Domain Authority Defined
In short, domain authority is a means of measuring how well a website will rank on search engines. Developed by Moz, domain authority scores range from one to 100—the higher the score, the better a website’s ability to rank in search. Sites like Wikipedia and Facebook are at the upper end of the DA score due to their large number of high-quality external links. Small businesses and websites with far fewer inbound links typically have much lower scores. Brand new websites will start with a domain authority score of one. A DA score is best used as a comparative metric rather than a definitive score.
