Domain Rating (DR)

Domain Rating is Ahrefs' proprietary metric estimating the strength of a website's overall backlink profile on a 0-100 scale, used industry-wide as a shorthand for a site's authority even by people who don't use Ahrefs directly. A similar metric, Domain Authority (DA), is Moz's competing version of the same concept.

DR and DA are widely used as quality filters in link building — a link from a DR 70+ site is treated as far more valuable than one from a DR 15 site. Several agencies reviewed on this site price their services directly around DR thresholds (Loganix's premium tier targets DR 70+ placements at $850/link, for example), making the metric directly relevant to what you're paying for.

Our Loganix, uSERP, and The HOTH reviews all reference DR/DA thresholds directly as a way of comparing placement quality across agencies.
