What’s the difference between UR and DR?

UR and DR are both metrics that ahrefs uses to determine the power of pages and domain-level authority. We use ahrefs metrics because we’ve found them to be most accurate in working out the value of a page or domain from an SEO standpoint. UR (short for URL rating) works out the power of a specific page. Pages with a high UR have the strongest correlation to 1st-page rankings in Google. In short – links from high UR pages move the needle. For more info on UR, check out this article.
