URL Rating (UR)
URL Rating is Ahrefs' score from 0 to 100 for how strong one page's backlinks are. It's a tool's estimate, which Google doesn't use.
URL Rating, or UR, is a score from Ahrefs that estimates how strong a single page's backlink profile is, on a scale from 0 to 100. A page with lots of links from pages that are well linked themselves scores high. A new page with no links scores close to zero. Ahrefs explains how it's worked out in its help article on URL Rating.
It's the page-level partner to Domain Rating, which scores a whole site. Marketers use it to compare pages: which of yours is strongest, or which page on another site is worth getting a link from.
How to read it
The scale isn't linear, so climbing from 70 to 80 takes far more than from 10 to 20. And UR is Ahrefs' own estimate from its own crawl of the web. Google doesn't use it, and other tools give the same page different scores.
For example, Fernhill Coffee is choosing between two pages to pitch for a mention: a big magazine's coffee guide with a UR of 45, and a specialist blog's grinder roundup with a UR of 22. The magazine page has the stronger links. Whether it's the better target depends on what you want from it.
UR vs being read by AI platforms
A page's link strength says little about whether AI platforms read it for your questions. Plenty of high-scoring pages never come up in answers, and some modest pages are cited again and again because they answer a common question clearly.
So for AI search, ask which pages the answers in your category actually use. Then use UR, if you like, to choose between pages that pass that test.
In AnswerOrbit
The Pages tab in Sources lists every page the answers used, with how many answers used it and how many times it was linked. The Gaps tab scores sources out of 100, half by how often answers use them and half by how many of your competitors they name.
