What is DR and UR in Ahrefs?

Domain Rating (DR) and URL Rating (UR) are the metrics Ahrefs uses to rate the backlink profile of a website.  DR is a measure of the quantity and quality of the backlinks going to an entire domain, while UR rates the backlinks going to a specific page.  While these metrics are useful, it is important to remember that websites do not rank solely because of their backlinks, and sometimes even a high ranking will not turn into traffic.
