Paste up to 50 domains and get the Ahrefs Domain Rating (DR) and URL Rating (UR) for each of them in one sortable table. The checker runs on your own Ahrefs API key, so every DR comes straight from Ahrefs, and you can switch to Moz, Semrush or DataForSEO to see their own authority scores, labelled as theirs.
Free, no sign-up. Without an API key you see example data, and your key stays in your browser.
Enter one domain per line, pick a data provider and press Run. Ahrefs is selected by default because Domain Rating is an Ahrefs metric. The table gets one column for each metric the chosen provider returns, with the provider's name in the column header, so an Ahrefs DR and a Moz DA never end up in the same column. Sort by any column, copy the rows into a spreadsheet or download them as CSV.
0 of 50 domains
Without a key the table shows example data.
Ahrefs returns Domain Rating (0 to 100) for the domain and URL Rating (0 to 100), which Ahrefs scores per URL rather than per domain. These are the only real DR and UR numbers.
Moz has no Domain Rating. It returns Domain Authority, Page Authority and Spam Score, its own scores from its own link index. DA is not DR and does not convert to it.
Semrush has no Domain Rating. It returns Authority Score, its own 0 to 100 score that combines link data with organic traffic and spam signals.
DataForSEO has no Domain Rating. It returns its own rank on a 0 to 1000 scale and a backlinks spam score from 0 to 100, both calculated from DataForSEO's own link index.
These rows are example data for fictional example domains, not real Ahrefs measurements. Add your own API key and press Run to check real domains.

Domain Rating (DR) is Ahrefs' score from 0 to 100 for the strength of a website's backlink profile. Ahrefs looks at how many unique domains link to a site with followed links, how strong those linking domains are by their own DR, and how many other sites each of them links to, since a domain that links out to thousands of sites passes less to each one. The result sits on a logarithmic scale, so the gap between DR 70 and 80 is much larger than the gap between 20 and 30.
DR is relative to the rest of Ahrefs' index. When very large sites gain links the scale shifts, and a site can drop a point or two without losing anything. DR also says nothing about traffic or topic: a site can have a high DR from links that bring it no visitors, and DR does not care whether those links are relevant to what the site is about.
Ahrefs shows DR in Site Explorer and in its free Website Authority Checker, one domain at a time. This domain rating checker asks the Ahrefs API instead, so you can check 50 domains in one run and download the table. API access is only part of some Ahrefs plans, so check yours before you create a key; the key dialog links to Ahrefs' API documentation.
Your key stays in this browser. Ahrefs' API does not accept calls straight from a browser, so each request passes through a small function on gscwizard.com that forwards it to Ahrefs without storing or logging your key or the results.
A bulk Ahrefs DR checker is most useful on lists: the domains ranking above you for a search, the sites you are considering for outreach, or the domains already linking to you. Sort the table by DR to see where you stand among competitors, or to separate strong prospects from weak ones before you spend time on them.
DR is a filter, not a verdict. A site with a modest DR that writes about exactly your topic is often worth more than a high-DR site that does not. For the links themselves, the backlink checker lists a domain's backlinks and referring domains.
People looking for a domain ranking often mean one of two things. If you want to know where a domain ranks in Google for a search, DR will not tell you: it is a link score, and a site with DR 20 can rank first for its own topic while a DR 80 site does not rank for it at all. Use the keyword rank checker for that, or for your own site the average position in Search Console.
If you want one number for how strong a domain's links are compared with other domains, DR is such a number, and so are the scores from Moz, Semrush and DataForSEO below, each measured in its own index.
Other link indexes have their own authority scores. They are useful, but none of them is Domain Rating, so the checker labels every number with the provider that produced it and never mixes two providers in one column.
| Score | Provider | Scale | Built from |
|---|---|---|---|
| Domain Authority (DA) | Moz | 1 to 100 | Linking root domains and link quality in Moz's index, fitted against Google results |
| Domain Rating (DR) | Ahrefs | 0 to 100 | The strength of a site's backlink profile in Ahrefs' index |
| Authority Score (AS) | Semrush | 0 to 100 | Link data, organic search traffic and spam signals |
| Rank | DataForSEO | 0 to 1000 | DataForSEO's own link index, with a PageRank-style calculation |
Do not convert one score into another. A site with DR 40 can have a DA of 25 or of 55, because each provider crawls a different part of the web and weighs links in its own way. If you report one of these numbers to a client, stick with the same provider over time. For Moz's score in bulk, use the domain authority checker.
One that is close to, or above, the sites you compete with for the same searches. DR has no fixed line between good and bad: DR 50 is strong in a small niche and low among national news sites. Put your domain and your competitors into the checker and compare them.
No. DR is an Ahrefs metric and Google never sees it. It tends to move with rankings because both depend partly on links, but Google uses its own link signals and many others.
No. Domain Rating comes from Ahrefs and Domain Authority from Moz. Both are 100-point link scores, but they are calculated from different link indexes with different formulas, so the same site can score quite differently on each. Compare DR with DR and DA with DA.
Because DR is relative. When other sites in Ahrefs' index gain links, the scale shifts, and sites that stood still can lose a point or two. A drop can also mean that some of the domains linking to you lost strength themselves, or that Ahrefs no longer finds some of your links.
DR scores a whole domain, UR (URL Rating) a single URL. A strong domain can have pages with a low UR, and a single page with many good links can have a higher UR than its domain's DR suggests.
In this browser only: in local storage if you choose to remember it, otherwise just for this session. Moz, Ahrefs and Semrush do not accept API calls straight from a browser, so those calls pass through a small function on gscwizard.com that forwards each request and does not store or log your key or the results. DataForSEO calls go straight from your browser to DataForSEO.
Domain Rating is a third-party estimate of link strength. For your own site you do not have to estimate: Search Console has the real clicks, impressions and average positions, and its Links report lists the sites Google has found linking to you. GSC Wizard, the Search Console tool I build, keeps that performance data beyond Google's 16-month limit and turns it into reports on decaying pages, keyword cannibalization, CTR opportunities and the effect of each Google update.
Free for the 7-day trial. After the trial you need a paid plan, from €17 a month, because there is no free plan for the web app.
