Domain Rating (DR) is a score from the SEO tool Ahrefs that shows how strong a website’s backlink profile is compared with every other site in Ahrefs’ database, on a scale of 0 to 100. It’s built only from links. Google doesn’t use it, and it says nothing about content, relevance or whether a site will rank for a particular search.
A high DR doesn’t win a search on its own. In Ahrefs’ snapshot of Google US results for “SD-WAN for healthcare,” taken in September 2026, the number one result came from a site with a DR of 52, and that page had no links pointing to it at all. Cisco, VMware, AT&T and HPE, all with DRs between 89 and 92, ranked below it with a configuration document, a Word file, a short article and a forum post. The page that answered a healthcare buyer’s question beat the strongest domains in the results.
How Ahrefs calculates DR
According to Ahrefs’ help documentation, DR works in a way loosely similar to Google’s original PageRank, but between whole websites rather than pages:
- It counts the domains that have at least one followed link to your site.
- Only the first link from each domain counts. A second link from the same site adds nothing.
- Each linking domain splits its strength across every site it links to. A DR 10 site linking to three domains can lift your DR more than a DR 80 site linking to a million.
- The scores are relative. Ahrefs says you can’t call any number good in absolute terms, only higher or lower than comparable sites.
Ahrefs adds that DR correlates with Google rankings less closely than its page-level metric, URL Rating (UR).
What Google says about scores like DR
Google’s guidance on third-party SEO tools, published in June 2026, says Google doesn’t evaluate or endorse third-party tools, and that those tools have no access to Google’s internal ranking data. DR is Ahrefs’ model of the link graph, built from Ahrefs’ own crawl. It can be a useful model, but it isn’t a measurement of anything Google uses.
Where DR is useful
DR earns its place in link building. When you have hundreds of possible sites to approach, it helps sort them. When I qualify link prospects, DR is one filter alongside the site’s organic traffic, its relevance to the client’s market, and who else it links to. A relevant site with a modest DR beats an irrelevant one with a high DR every time.
It’s also a reasonable way to compare your link profile with direct competitors. If every site ranking for your main terms has a DR around 60 and yours is 20, links are part of the gap. If yours is similar, links aren’t the problem.
Common mistakes
- Treating DR as a Google ranking factor. Google says third-party tools have no access to its ranking data.
- Setting a DR target as a goal, such as “reach DR 50.” The number follows links. It doesn’t cause rankings.
- Buying links from high-DR sites that have nothing to do with your market.
- Comparing DR across industries. A strong DR for a niche B2B manufacturer looks weak next to a news site, and it doesn’t matter.
- Judging a page by its site’s DR, when the page itself may have no links at all.
