    Domain Rating

    Also called: DR, Domain Authority, DA

    Domain Rating is Ahrefs' 0 to 100 score of how strong a website's backlink profile is, and Domain Authority is Moz's version of the same idea; Google uses neither.

    In practice

    They are useful for comparing two sites in the same market and for spotting whether a link prospect is real. A local contractor site with a DR of 10 to 20 is normal, and a competitor at 30 has links worth looking at.

    An agency that reports DR as a result has nothing else to report.
