What is Domain Rating (DR)?

Domain Rating (DR) is a proprietary SEO metric developed by Ahrefs that measures the overall strength of a website's backlink profile on a logarithmic scale from 0 to 100. The higher the score, the stronger the site's authority in the eyes of search engines — and the more likely it is to rank well across a broad range of keywords.

DR is calculated by looking at how many unique domains link to a target website, how strong those linking domains are themselves, and how many other sites each of those domains links out to. This PageRank-inspired approach means that a single link from a high-DR authoritative site (think Wikipedia or the BBC) can be worth far more than hundreds of links from low-quality, low-DR domains.

Because the scale is logarithmic, climbing from DR 20 to DR 30 is considerably easier than moving from DR 70 to DR 80. At the top of the scale, even small gains reflect an enormous number of high-quality backlinks being acquired. This is why very few websites ever reach DR 90+, while millions sit between DR 0–30.

It is important to understand that DR is a relative metric. Ahrefs continuously recalibrates scores across its entire index of billions of web pages, meaning a site's DR can fluctuate even if its actual backlink count hasn't changed — simply because the broader landscape has shifted. A DR of 50 today represents the same relative position among all indexed sites, even if the absolute link counts behind that score change over time.

Understanding the DR Scale

Here is how Domain Rating scores generally map to website authority levels. These are practical benchmarks, not official Ahrefs tiers:

DR Range	Authority Level	Typical Examples
0–9	Very Weak	Brand new or barely linked sites
10–29	Weak	Small blogs, local businesses, new startups
30–49	Fair	Established niche sites, growing SaaS tools
50–69	Good	Mid-size publishers, well-known tools
70–89	Strong	Major industry blogs, large news sites
90–100	Elite	Wikipedia, YouTube, BBC, major platforms

How DR is Calculated

Ahrefs computes Domain Rating using a multi-step algorithm inspired by Google's original PageRank concept. The core idea is that links pass "authority" between domains, and the amount passed depends on both the quality and the linking behaviour of the referring domain.

Step 1 — Count unique referring domains. Ahrefs identifies how many unique domains link to the target site using dofollow backlinks. Duplicate links from the same domain count only once. The raw number of referring domains forms the starting point of the calculation.

Step 2 — Weight by the linking domain's own DR. Not all referring domains are equal. A link from a DR 80 site transfers considerably more authority than one from a DR 10 site. Ahrefs weights each contribution by the referring domain's DR score, creating a feedback loop that rewards quality over quantity.

Step 3 — Adjust for outbound link volume. A domain that links to thousands of sites distributes its authority thinly across all of them. The algorithm divides a domain's contribution by the total number of unique domains it links out to. This prevents "link farms" and mass-linking sites from artificially inflating the DR of their targets.

Step 4 — Normalise to a 0–100 logarithmic scale. The raw scores are mapped to a standardised 0–100 scale. Because the scale is logarithmic, differences at the top end are far more significant than the same numerical gap near the bottom. Ahrefs periodically recalibrates the scale to keep scores meaningful as the web grows.

DR vs. Other Authority Metrics

DR vs. Moz Domain Authority (DA): Both metrics aim to predict a domain's ranking potential based on backlinks, and both use a 0–100 logarithmic scale. The key difference is data source and algorithm. Ahrefs crawls more of the web more frequently than Moz, which many SEOs argue makes DR a more accurate and up-to-date signal. DA also factors in a few on-page signals, while DR is strictly a backlink metric.

DR vs. Semrush Authority Score: Semrush's Authority Score incorporates not only backlink data but also organic traffic signals and spam detection. This makes it a broader (but also more opaque) metric. DR is more focused — it measures backlink profile strength and nothing else, which makes it easier to reason about when evaluating link-building opportunities.

DR vs. URL Rating (UR): UR is Ahrefs' page-level equivalent of DR. While DR measures the authority of an entire domain, UR measures the authority of a specific URL. When evaluating a backlink opportunity, you want to look at both: DR tells you how strong the site is overall, while UR tells you how much authority the specific linking page actually carries.

DR vs. Google PageRank: Google deprecated the public PageRank toolbar in 2016, so there is no official Google score available to webmasters anymore. DR (and DA, AS, and similar metrics) exist precisely to fill this gap. None of them are Google PageRank, but DR correlates well with ranking performance across large data studies, making it a reliable proxy for link evaluation.

How to Improve Your Domain Rating

Improving DR comes down to one thing: earning more high-quality backlinks from authoritative, relevant websites. That said, there are both strategic and tactical levers to pull:

Create link-worthy content. The most sustainable path to a higher DR is producing content that other websites genuinely want to reference. Original research, comprehensive guides, free tools, interactive data visualisations, and well-argued opinion pieces all attract natural backlinks without outreach.

Digital PR and data-driven campaigns. Publishing proprietary data studies or surveys gives journalists and bloggers a reason to link back to you as the original source. A single well-placed piece of research can generate dozens of high-DR referring domains in a short period.

Guest posting on relevant sites. Contributing articles to authoritative publications in your niche earns backlinks while also building your reputation. Focus on topical relevance — a link from a closely related DR 50 site is usually more valuable than one from an unrelated DR 70 site.

Reclaim unlinked mentions. Use tools like Ahrefs Content Explorer or Google Alerts to find places on the web that mention your brand without linking to you. A simple outreach email asking for the link converts at a surprisingly high rate because the mention already exists.

Fix and redirect broken backlinks. Identify pages on your site that have disappeared but still have backlinks pointing at them. Redirecting these to relevant live pages recovers lost authority that is already waiting to be claimed.

Be patient. Because DR uses a logarithmic scale, early gains (from 0 to 30) can come relatively quickly with focused link-building. Moving from DR 50 to DR 60 requires significantly more effort, and the top of the scale (DR 80+) typically reflects years of sustained authority-building.

Frequently Asked Questions

No. DR is an Ahrefs metric, not a Google signal. Google has never confirmed using any third-party authority score in its ranking algorithm. However, DR correlates strongly with organic ranking performance in large-scale studies because strong backlink profiles tend to result in higher Google rankings — not because Google reads the DR score itself, but because the underlying backlinks that drive a high DR are exactly what Google's own algorithm rewards.

Ahrefs periodically recalibrates its DR scale relative to all other websites in its index. If a large number of websites gained strong new backlinks and therefore had their DR increase, your site's relative position on the scale can decrease even if your absolute backlink count remained the same. A DR drop is not always bad news — it may simply reflect that the competition got stronger, not that your site got weaker.

Ahrefs crawls the web continuously, and DR scores are updated on a rolling basis as new backlink data is processed. Most domains see their DR refreshed at least a few times per month, though the exact frequency depends on how actively the site and its referring domains are being crawled. New backlinks can take anywhere from a few days to a few weeks to be reflected in the DR score.

There is no universal answer — it depends entirely on your niche and competition. A DR of 30 might be excellent for a local plumber competing against other local businesses, while a DR of 60 might be considered average in a competitive SaaS market. The most useful benchmark is to compare your DR against your direct competitors. If your DR is close to or higher than the sites currently outranking you, links are probably not your limiting factor.

Indirectly, yes. A high domain DR means the site has a strong overall backlink profile, and Ahrefs' research suggests that internal links distribute some of this authority across all pages on the domain. However, the page-level metric that matters most for individual URL rankings is URL Rating (UR), not DR. Both are worth monitoring — DR for the domain's competitive standing, UR for the ranking potential of specific pages.

In theory, yes — purchasing large volumes of links from high-DR domains can inflate a site's DR. However, Ahrefs has implemented filters to detect and discount obvious link schemes, and Google's own algorithms (Penguin) actively penalise sites that engage in unnatural link building. A manipulated DR that doesn't reflect genuine editorial links will rarely translate into actual search rankings, and the risk of a Google penalty far outweighs any short-term gain.

DR measures the backlink profile strength of an entire domain, while URL Rating (UR) measures the strength of a single page's backlink profile. A site can have a high DR but a low UR on a specific page if that page has very few direct backlinks. Conversely, a single viral page can have a higher UR than the domain's DR would suggest. When evaluating link-building prospects, check both: DR tells you how authoritative the site is, UR tells you how much link equity the specific page will pass.

No. DR is a useful competitive signal, but rankings depend on many factors that DR doesn't capture: content quality and topical relevance, technical SEO health, page speed, user engagement signals, and the intent-matching of your pages to search queries. A site with DR 40 and exceptional content can absolutely outrank a DR 70 site with thin or poorly optimised pages. Think of DR as one data point in your competitive analysis, not a guarantee of outcome.

Buying backlinks violates Google's Webmaster Guidelines and carries a significant risk of manual or algorithmic penalties. While paid links can temporarily inflate DR, Ahrefs and Google both work to identify and discount unnatural links. The sustainable path is earning links through quality content, digital PR, and genuine relationship-building. The sites that maintain high DR scores year over year almost universally do so through editorial links, not paid placements.
