Domain Rating (DR)

Quick Definition

Domain Rating is Ahrefs's 0–100 metric for domain backlink strength on a logarithmic scale.

In context

DR is one of the more accurate proxies for backlink strength. Going from DR 30 to DR 50 takes roughly 10x the link strength. Use it as one input into competitive analysis rather than a target metric.
