DR (Domain Rating)

DR is a logarithmic score from 0 to 100 that measures the strength of a domain's backlink profile. It's a proprietary Ahrefs metric, but the SEO industry treats it as a de facto standard. New domains start at 0; established indie SaaS sites typically land in the 20–50 range; major software companies live in the 70+ range. DR from a backlink matters because higher-DR sites transfer more "link juice" — a backlink from a DR 60 site is worth roughly 10× a backlink from a DR 20 site.
