What is Domain authority & Page authority?
Domain Authority is Moz's calculated metric for how well a given domain is likely to rank in Google's search results. It is based off data from the Mozscape web index and includes link counts, MozRank and MozTrust scores, and dozens of other factors. It uses a machine learning model to predictively find an algorithm that best correlates with rankings across thousands of search results that we predict against.
Page Authority is Moz's calculated metric for how well a given webpage is likely to rank in Google.com's search results. It is based off of the Mozscape web index and includes link counts, mozRank, mozTrust, and dozens more. It uses a machine learning model to predicatively find an algorithm that best correlates with rankings across thousands of search results that we predict against.
It's best to use Page Authority (PA) and Domain Authority (DA) as comparative metrics when doing research in the search results and determining which sites/pages may have more powerful/important link profiles than another.
