Domain Authority is a score developed by Moz that predicts how well a website will rank on search engine result pages (SERPs). DA is not an authority metric used by Google in determining search rankings but, instead, a third-party tool used for benchmarking and competitive link analysis. It is also a relative measure, meaning that it is most useful when comparing one domain's authority to another rather than as an absolute score of a website's traffic and performance.
