To improve your website's search engine ranking, backlinks are a must. For this reason, developing a strong backlink profile is crucial. The higher your site ranks, the more robust your backlink profile is, both in terms of quantity and quality.
The query? How is your backlink profile calculated?
It turns out that Ahrefs provides a metric called Website Rating for that.


DNS Rating is a proprietary Ahrefs metric that shows the “link popularity” of your website compared to all other websites in the world.

It shows the strength of a given website’s overall backlink profile (in terms of its size and quality) and is measured on a “logarithmic scale” from 1 to 100, with the latter being the strongest.

  • Link popularity refers to a specific way that Ahrefs calculates website ratings.
  • The logarithmic scale means that the gap between DR 82–83 is much bigger than the one between DR 22-23. In other words, the higher your DR gets, the more challenging it will be to grow it by another few points.

Website Domain check is one of the most prominent metrics in Ahrefs you can see it in nearly every one of their report.

Lots of people check it religiously because it gives an idea of how well a website is doing in terms of links.

Domain Grade is not about the keywords your website ranks for, the search traffic it gets, or some type of website authority that your site has. Instead, it is primarily a calculation of your backlink profile.


Ahrefs calculates Domain Grade using the following metrics:

  • The number of unique domains with at least one do-follow link, pointing to your website.
  • The values of those domains (whose links are pointing to your website).
  • The total number of unique outgoing links (to other sites) each of those websites has.

After getting these three metrics, Ahrefs will then apply some mathematics and coding magic to calculate “raw” scores, after which they'll plot these scores on a 1–100 scale.

Understanding this calculation method helps you know how you can improve your Domain Rating. But here's what you also need to understand about improving your score per the calculations:

  • Only do-follow links improve Domain Grade. Thus, if the website is only linking to you via nofollow links, it won’t increase your URL reputation.
  • The more unique websites a site links to, the less points it will transfer to each of those sites.
  • The second, third, and subsequent links from the same website will not improve your site's score.
  • If the linking website gets more backlinks and its rating increases, that will positively affect the DNS Rating of each website they link to (only do follow).
