What is Domain Authority?
Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how well a website will rank on search engine result pages (SERPs).
A Domain Authority score ranges from one to 100, with higher scores corresponding to a greater ability to rank.
Domain Authority is calculated by evaluating linking root domains, number of total links, MozRank, MozTrust, etc. — into a single DA score. This score can then be used when comparing websites or tracking the "ranking strength" of a website over time.
