What is Domain Rating? Complete Guide to Ahrefs DR

What is Domain Rating (DR)?

Domain Rating (DR) is a search engine ranking metric developed by Ahrefs that measures the overall strength of a website's backlink profile. DR scores range from 0 to 100, with higher scores indicating a stronger, more authoritative backlink profile.

While Domain Authority (DA) from Moz predicts overall ranking potential using many factors, Domain Rating focuses specifically on the strength of your backlinks. Think of DR as a focused "link power" score — it answers the question: based purely on the sites linking to this domain, how strong is its link profile?

How Ahrefs Calculates Domain Rating

Ahrefs calculates DR using a proprietary algorithm that is conceptually similar to Google's original PageRank. The calculation works in three main steps:

1. Ahrefs looks at how many unique domains link to the target site. The number of referring domains (unique linking sites) is the foundation of DR — more unique domains generally means a higher DR.
2. It accounts for the DR of those referring domains. A link from a DR 80 site passes far more "DR juice" than a link from a DR 10 site. High-DR referring domains are weighted much more heavily.
3. It applies a damping factor and normalizes to 0-100. Ahrefs spreads link equity across all the outbound links a referring domain makes, then applies a damping factor (so equity doesn't loop infinitely) and normalizes the final score to the 0-100 scale.

The key insight is that DR is purely about links — it does not consider content quality, on-page SEO, traffic, or user engagement. This is what makes it different from Moz's DA.

Domain Rating Score Ranges

DR uses a logarithmic scale, which means it is much harder to grow from DR 70 to 80 than from DR 10 to 20. Here is how to interpret DR scores:

Important: Like DA, DR is comparative. A DR of 50 might be excellent in a niche where competitors sit at DR 30, but weak if your competitors are at DR 70+. Always benchmark against the sites you actually compete with in search results.

DR vs DA: Key Differences

Domain Rating and Domain Authority are the two most widely used authority metrics, but they come from different companies and measure slightly different things. For a full side-by-side breakdown, see our DA vs DR comparison guide.

Key insight: Because DR is purely link-based, a content-heavy site with a modest link profile may have a higher DA than DR. Conversely, a site with many strong backlinks but thin content may have a higher DR than DA. When both metrics agree, you can be more confident in your assessment; when they diverge, investigate why.

How to Check Domain Rating

The easiest way to check DR is with our free Domain Rating Checker tool:

1. Enter a domain name (e.g., example.com)
2. Click "Check Domain Rating"
3. View the DR score instantly — no Ahrefs subscription required

For checking DR alongside Moz DA and Spam Score, you can also use our DA PA Checker, which reports multiple authority metrics in one place.

How to Increase Domain Rating

Because DR is driven entirely by your backlink profile, increasing DR means building a stronger, broader, higher-quality link profile. The strategies are largely the same as those for increasing Domain Authority, with an emphasis on link quality:

• Earn links from high-DR sites. A single link from a DR 80 domain can move your DR more than dozens of links from DR 10 domains.
• Diversify your referring domains. DR rewards unique linking domains — 100 links from 100 different domains beats 1,000 links from one domain.
• Create linkable assets. Original research, free tools (like our DA PA Checker), and comprehensive guides naturally attract links.
• Remove toxic backlinks. Use the Spam Score Checker to identify and disavow harmful links that drag down your profile's quality.
• Be patient. DR is logarithmic; meaningful gains take months of consistent, high-quality link building.

Common Domain Rating Myths

Myth 1: "DR is a Google ranking factor." Reality: DR is an Ahrefs metric, not a Google signal. But because DR reflects backlinks — which are a Google ranking factor — a higher DR often correlates with better rankings.

Myth 2: "A higher DR guarantees higher rankings." Reality: DR measures link strength only. Content relevance, quality, and on-page SEO still determine whether you rank for a given query.

Myth 3: "DR and DA should always be similar." Reality: They often differ by 10-15 points because they use different data and algorithms. Large gaps signal something unusual about your link profile versus your broader authority signals.

Conclusion

Domain Rating is one of the most useful metrics for evaluating the strength of a website's backlink profile. While it is not a Google ranking factor, the link strength it reflects is directly tied to how well a site can compete in search results.
