What is Domain Rating (DR) in SEO?
Understand Ahrefs' 0-100 score for backlink strength, how it is calculated, and how to use it wisely in your SEO strategy.
Definition
Domain Rating (DR) is a proprietary metric developed by Ahrefs that measures the relative strength of a website's backlink profile on a logarithmic scale from 0 to 100. The higher the DR, the stronger and more authoritative the domain's inbound link profile appears to be.
DR is calculated similarly in principle to Google's PageRank, but at the domain level rather than the page level. It reflects "link popularity" - how many quality websites link to a domain - not the overall quality, traffic, or trustworthiness of the site itself.
DR is not a Google metric. It is a third-party score used by SEOs, marketers, and site owners to compare domains, evaluate link-building targets, and track the progress of their backlink efforts over time.
How Domain Rating is calculated
Ahrefs calculates DR using its index of backlinks. According to their documentation, three main factors determine the score:
- Number of unique referring domains - Only domains with at least one followed (dofollow) link to the target site count. Nofollow links do not improve DR. Only the first followed link from each domain counts - ten links from the same site have the same effect as one.
- DR of the linking domains - A backlink from a DR 80 site carries far more weight than one from a DR 15 site. Your DR can also rise if the domains linking to you increase their own DR over time.
- Link dilution from outbound links - The more unique domains a linking site points to with followed links, the less "DR equity" it passes to each one. A link from a DR 93 site that links to 3,000 other domains is worth more than one from a DR 93 site linking to 300,000 domains.
DR uses a logarithmic scale, so gains get harder at higher levels. Moving from DR 10 to 20 may take only a few quality backlinks, while going from DR 70 to 80 can require hundreds. The exact formula is proprietary and DR is recalculated as Ahrefs recrawls the web.
What DR does not measure
Ahrefs is clear that DR should not be used as a standalone quality indicator. The metric is purely link-based and ignores several important factors:
- Organic search traffic - A site can have high DR but little actual visibility in Google.
- Content quality or relevance - DR says nothing about whether a site's content is useful, accurate, or related to your niche.
- Domain age or brand reputation - A well-known brand with few backlinks may have low DR, while a spammy site with many manipulated links may score higher.
- Individual page strength - DR applies to the whole domain. A DR 60 site can still have pages with weak backlink profiles. For page-level analysis, use URL Rating (UR) instead.
Ahrefs recommends pairing DR with other signals - such as organic traffic, URL Rating, or topical relevance - before deciding whether a backlink opportunity is worth pursuing.
What is a good Domain Rating?
DR is a relative scale - what counts as "good" depends on your niche and competitors. These ranges are commonly used as a rough guide:
0 - 20
Low DR. New or small sites with few backlinks, or domains relying on low-quality link sources.
20 - 40
Moderate DR. Many blogs, niche sites, and growing businesses sit in this range.
40 - 60
Strong DR. Established sites with a solid, diverse backlink foundation.
60 - 80
Very strong DR. Authoritative publishers and well-known brands in their space.
80 - 100
Elite DR. Major platforms and global brands (think Wikipedia, GitHub, Amazon). Reaching this tier requires an exceptional backlink profile.
A link from a DR 30 site in your industry is often more valuable than one from a DR 60 site in an unrelated topic. Always weigh relevance and trust alongside the number.
Why Domain Rating matters for SEO
Prioritize link-building targets
When choosing where to earn a backlink - directories, guest posts, partnerships - DR helps you compare options quickly. A followed link from a higher-DR, relevant site typically passes more authority than one from a low-DR source.
Evaluate directories and partners
Before listing your site in a directory or partnering with another website, checking DR gives a quick sense of how much link equity you might receive. WebProjectList aims to maintain a strong profile so your listing delivers a meaningful SEO benefit.
Track your own progress
As you earn quality backlinks, your domain's DR tends to rise over time. It is one way to gauge whether your link-building efforts are working - though rankings and traffic matter far more than the number itself.
Benchmark against competitors
Comparing your DR to competitors in the same niche reveals gaps in your backlink profile. If rivals consistently outrank you with similar content, their stronger DR may be a contributing factor.
DR and similar metrics
Several SEO tools estimate domain-level authority with their own algorithms and data. The most common alternatives:
Domain Authority (DA)
Moz's 0-100 score based on its own link index. Similar in purpose to DR but uses different data and calculations. A site with DR 50 may have DA 35 or DA 65 - the numbers are not interchangeable.
Authority Score (AS)
Semrush's domain strength metric, also on a 0-100 scale. It factors in backlink quality, organic traffic, and spam signals. Again, AS and DR will rarely match for the same domain.
URL Rating (UR)
Also from Ahrefs, but measures a single page rather than the whole domain. UR includes both external and internal links. Use UR when evaluating the strength of a specific page or URL.
Ahrefs Rank (AR)
A global ranking of all websites in Ahrefs' database by backlink profile strength. AR #1 is the strongest site. It is the ordered version of DR - useful for seeing where a domain stands worldwide.
Pick one metric and stick with it for comparisons. Mixing DR, DA, and AS as if they were the same scale will lead to misleading conclusions.
How to improve your Domain Rating
DR increases when you earn more followed backlinks from unique, high-DR domains. Focus on sustainable, white-hat tactics:
- • Create link-worthy content - Original research, data studies, free tools, and in-depth guides attract natural citations from bloggers and journalists.
- • Quality directories - Listing in curated, relevant directories like WebProjectList that have a solid DR and real editorial standards.
- • Guest posting - Publishing useful articles on respected sites in your niche in exchange for a contextual followed backlink.
- • Digital PR and mentions - Press coverage, expert roundups, and resource pages can earn links from high-DR publishers.
- • Broken link building - Find broken links on relevant sites and suggest your content as a replacement.
- • Diversify referring domains - Earning links from many unique domains matters more than stacking multiple links from the same site.
Avoid buying links, link farms, private blog networks (PBNs), and mass directory submissions. These tactics can trigger Google penalties and often fail to improve DR sustainably. Learn more about earning links in our guide on what is a backlink.
Frequently asked questions
Domain Rating (DR) is a proprietary metric developed by Ahrefs. It estimates the relative strength of a domain's backlink profile on a logarithmic scale from 0 to 100. Other SEO tools offer similar scores, such as Moz's Domain Authority (DA) or Semrush's Authority Score.
DR is relative and niche-dependent. As a rough guide: 0-20 is low, 20-40 moderate, 40-60 strong, 60-80 very strong, and 80-100 reserved for major brands and platforms. What matters most is earning relevant backlinks from trusted sites in your industry, not chasing a number.
No. DR is a third-party metric from Ahrefs, not a Google ranking factor. Google uses its own signals to evaluate authority and relevance. DR is useful for SEOs to compare domains and prioritize link-building opportunities.
DR measures the strength of an entire domain's backlink profile. URL Rating (UR) measures the strength of a single page, including both external and internal links pointing to it. A domain can have high DR while individual pages have low UR if those pages lack direct backlinks.
DR can fall even if you did not lose backlinks. Because DR is a relative score on a fixed 0-100 scale, when other sites gain links your position can shift downward. Lost links, linking domains that lost DR themselves, or a drop in link quality can also cause a decrease.
Earn more followed backlinks from unique, high-DR domains that are relevant to your niche. Tactics include creating link-worthy content, guest posting, digital PR, and listing in trusted directories. Avoid buying links, link farms, and private blog networks.
