Domain Rating and Domain Authority

Domain Rating and Domain Authority are 100-point scores invented by SEO tool companies to estimate how strong a site's link profile is.

Domain Rating is Ahrefs' version and Domain Authority is Moz's, and the 2 numbers usually differ.

Neither is a Google metric, and Google doesn't use either in its rankings.

They're still useful as a comparison, since a competitor at 42 against your 8 says something real about the gap between your link profiles.

Ahrefs and Moz both describe their scales as logarithmic, so moving from 10 to 20 is a far smaller job than moving from 60 to 70.

Treat movement in the score as a progress signal and never as the goal itself.

What this means for you

I use it for comparison and report on what pays the bills, meaning clicks, calls and enquiries from Google.

This one sits under SEO.
