Domain Rating (DR4)
DR is an Ahrefs 0–100 metric for referring domains. DR4 is current. We call the free official endpoint. Input, lookup, and answer stay on this page. Not a Google rank.
We only show numbers the free Ahrefs DR4 endpoint actually returned. The lookup and the answer both stay on this site: if we cannot get one, we say so — no estimate dressed up as a fact, and no trip to another site.
