DR4 scores. Familiar sites checked November 5, 2026.
No Domain Rating came back for this domain. Common reasons: the site is new, few rated sites link to it, or it's one of the many sites DR4 no longer scores (it rates about half as many as DR3 did). Check the spelling, or try the main domain if you entered a subdomain.
| Domain | DR3 | DR4 | Change | DR4 on a 0 to 100 scale |

Sorted by DR4, highest first.
Domain Rating runs from 0 to 100. The higher the number, the stronger the overall set of websites linking to you. The scale gets harder as you climb: going from 70 to 80 generally takes far more than going from 10 to 20.
Your score makes the most sense next to sites you know. Here's where a few example sites sit today.
75 marketing tools, publishers, platforms and subdomains, scored with DR3 and DR4 on November 5, 2026 (72 had both scores). Change means DR4 minus DR3: it compares two scoring models, not links gained or lost.
On November 5, 2026, github.io had the biggest drop in this sample, from DR 94 to 64, and convertkit.com had the biggest gain, from 87 to 91. Of 72 sites scored, 28 went up, 27 went down and 17 held steady. Subdomains made up 8 of the 10 biggest drops.

This checker is built for the switch to DR4, so it shows what changed and what it means:
Domain Rating (DR) is a score from the SEO software company Ahrefs that rates how strong a website's backlinks are compared to every other site in its database, on a scale from 0 to 100. It's a score for links. It isn't a traffic estimate, and it doesn't score content, design or how old a domain is. (DR4 does use each linking site's estimated search traffic to weigh its links.)
Here's the simple version of how it works. Every site that links to you passes along part of its own rating. That share is split evenly across every site it links to, so the fewer sites it links to, the more each one gets:
Because DR compares you to everyone else, your score can drop when other sites gain links faster than you do, even if you lost nothing.
DR4 was announced on November 5, 2026, and it becomes the default score on December 1, 2026. Four changes matter most.
91 → 77
Under DR3, blog.example.com usually showed the same DR as example.com. Under DR4, each subdomain is rated on the links pointing to it. help.ahrefs.com fell from 91 to 77.
More weight
DR is still built from links, but DR4 gives more weight to links from sites that get estimated search traffic. A smaller group of sites now moves everyone else's score.
About ½
Because of that smaller, higher-quality pool, about half as many sites have a DR4 score as had a DR3 score. Some small sites now show no DR at all.
−15 to −20
Sites labeled as spam (by a machine learning model in use since January 2026) that had a DR3 between 30 and 70 dropped by a median of about 15 to 20 points. For everyone else, the median change was close to zero.
DR3 (old)
DR4 (new)
Is the new score closer to how sites rank in Google? Across 10 million sites, DR4 lined up more closely with the number of top 10 Google rankings overall, while DR3 still did better for main domains alone:
| Sites tested | Count | DR3 vs top 10 | DR4 vs top 10 |
|---|---|---|---|
| All sites (main domains and subdomains) | 10,000,000 | 0.140 | 0.359 |
| Main domains | 5,231,436 | 0.407 | 0.304 |
| Subdomains | 4,768,564 | 0.172 | 0.259 |
Correlation with the number of top 10 Google rankings (1.0 would be a perfect match), from the DR4 announcement. Correlation shows a pattern, not cause.
Of the 1,000 websites estimated to get the most search traffic in the world:
For sites whose DR fell, the drop was usually small: a median of 4 points (the average was 7.3). The big exception is github.io, the domain behind GitHub Pages, which lost about 30 points. Its subdomains still score on their own: facebook.github.io sits at DR 86. These figures come from the DR4 announcement, so a few differ slightly from today's live scores.
A lower score under DR4 can have a few explanations. Check which ones fit your site:
Keep it in perspective. DR only reflects links, so a lower score is no comment on your content, design or value to your audience. The best reality check is your competitors. Paste your domain and up to 9 rivals into the checker, separated by commas, and see if they moved the same way.
There's no universal good score. A good DR is one that's higher than or close to the sites you compete with. DR 20 can be the strongest site in a local market. A software company at DR 60 can still be the weakest site on page one of Google.
Compare against three groups instead of chasing one number: your direct competitors, 20 to 30 companies across your industry, and the sites already ranking for the keywords you want. For a sense of scale, a study of 600 software (SaaS) companies looked like this, measured on DR3 before the switch:
| SaaS benchmark | DR |
|---|---|
| Bottom quarter | 38 |
| Median company | 62 |
| Top quarter | 77 |
| Top 10% | 86 |
From Ryan Law's What Is a Good Domain Rating? (With Real Data), June 2026.
You'll also see fixed score bands floating around, like "0 to 30 is new, 50 to 70 is good." Those are rules of thumb, not official definitions. With DR4 shrinking the pool of rated sites, compare against real competitors instead.
DR4 rewards the same thing DR always did, links from strong sites, but it's stricter about what strong means. What works now:
DR doesn't measure whether your business shows up in AI answers. My free AI Visibility Audit checks that separately, and the AI SEO strategy guide covers what to do about it.
Domain Rating measures how strong a site's backlinks are compared to other sites. Domain Authority (DA) comes from Moz, a different SEO company, and predicts how likely a domain is to rank. Both run from 0 to 100, but each company crawls the web on its own and scores with its own formula. A site can be DR 45 and DA 30 at the same time, and neither number is wrong.
Don't mix them. If you report DR for your site, report DR for your competitors too. And neither one is a Google metric. Google has never used DR or DA to rank pages.
Type your domain into the checker at the top of this page. You get the new DR4 score next to the old DR3 score and the change between them, plus a chart that shows how your score compares to familiar sites. No signup or account needed. You can check a subdomain like blog.yoursite.com too, or paste up to 10 domains separated by commas to compare them.
Domain Rating (DR) is a 0 to 100 score for how strong a website's backlinks are compared to other websites. A higher score means more sites, and stronger ones, link to it. It isn't a Google score, and it doesn't measure traffic or content quality.
DR4 is the newest version of Domain Rating, announced on November 5, 2026. It scores each subdomain on its own, gives more weight to links from sites that get search traffic, and cuts the scores of spam sites. Across 10 million sites it lined up more closely with top 10 Google rankings than the old DR3 did (0.359 vs 0.140), though DR3 still did better for main domains alone.
On December 1, 2026. The old DR3 scores stay available for a short time after the switch, so this checker shows the before and after for as long as both exist. After that it keeps working and shows DR4 only.
A few things can cause it. Links from sites with little or no search traffic count for less under DR4, some of the sites linking to you may have lower scores after being labeled spam, or your site is a subdomain that used to borrow its main domain's rating. DR only counts links, so a lower score says nothing about your content. Compare your closest competitors, since many saw similar moves.
There's no single good number. A good DR is one that's higher than or close to the sites you compete with. Most websites sit between 0 and 10, while household-name brands sit in the 90s. Compare yourself against the sites ranking for your keywords, which is why this tool checks up to 10 domains at once.
Yes. Under DR4, a subdomain gets its own rating based on the links pointing to it. For example, on November 5, 2026, blogs.microsoft.com scored DR4 89 while microsoft.com scored 94, and help.ahrefs.com dropped from 91 to 77. If your blog or store lives on a subdomain, check it separately from your main domain.
No. Domain Rating is a third-party SEO score, and Google doesn't use it. It estimates how strong a site's backlinks are compared to other sites. Use it to size up competitors, judge link opportunities and gauge how hard a search result might be to crack, not as a number to chase.
DR (Domain Rating) measures how strong a site's backlinks are compared to other sites. DA (Domain Authority) is a separate score from Moz that predicts how likely a domain is to rank. Both run from 0 to 100, but each uses its own link data and formula, so the numbers don't line up. Pick one and use it the same way for every site you compare.
This site doesn't keep a history of the domains you check. Scores are cached by domain for up to 12 hours so repeat checks and share links load fast, and there's a fair-use limit per visitor so the free service stays up for everyone.

Domain Rating is created by Ahrefs, the SEO software company behind it. Every score in this checker comes from Ahrefs' free Domain Rating API and is cached for up to 12 hours. They're the real scores, not an estimate or a lookalike formula. While both models are available, the checker shows DR3, DR4 and the change. Once DR3 is retired after the December 1 switch, it keeps working as a DR4 checker.
