What Does Domain Rating Measure?
Domain Rating is an Ahrefs metric that estimates the relative strength of a website's backlink profile. The value runs from 0 to 100 on a logarithmic scale, which means progress generally becomes harder at higher levels. DR Checker reports that domain-level value; it does not calculate a separate proprietary authority score or quietly blend unrelated metrics into the number.
What Is a Good DR Score?
There is no universal score that becomes good for every website. A local service business, a new software product, an established publication, and a global marketplace operate in very different link environments. Use DR Checker to establish a relevant benchmark: check direct competitors, websites ranking for the same topics, and realistic partnership candidates. A result of 30 may be competitive in one niche and ordinary in another.
When Should You Use DR Checker?
DR Checker is useful during competitor research, outreach qualification, backlink audits, partnership reviews, expired-domain research, directory assessment, and recurring client reporting. For outreach, a result can help you prioritize a long list, but topical relevance and editorial quality should still decide whether a placement is worthwhile. For competitor work, the score can reveal an authority gap that deserves deeper backlink analysis.
What DR Checker Cannot Tell You
DR Checker cannot prove that a website is trustworthy, relevant, or likely to rank for a keyword. Domain Rating is not a Google metric or direct ranking factor. A strong DR Checker result can still be a poor fit, so review actual backlinks, traffic, content quality, and topical alignment before making an important decision.

DR Checker Frequently Asked Questions
These answers cover the questions people most often ask before using DR Checker for domain authority research, comparisons, and monitoring.
Is this DR Checker free to use?
You can review available Domain Rating data without buying a full research platform. Account, usage, and refresh limits may apply to prevent wasteful repeat requests.
Where does the DR Checker data come from?
DR Checker uses Domain Rating data supplied through Ahrefs, which measures the relative strength of a website's backlink profile on a 0-100 scale. Recent results are stored and refreshed according to the service rules.
How often does DR Checker update a result?
Public DR Checker results refresh at most once within 24 hours. A recent cached or stored value may be returned because backlink-based metrics are trends, not second-by-second measurements.
Is Domain Rating a Google ranking factor?
No. Domain Rating is an Ahrefs metric, not a score created by Google. DR Checker can compare backlink-profile strength, but the score does not guarantee rankings or traffic. Use it alongside content quality, search intent, technical health, and backlink analysis.
Why did my DR Checker score go down?
A lower result can reflect lost links, weaker referring domains, attribute changes, or growth elsewhere in Ahrefs' relative index. Compare dates and review new or lost referring domains before assuming a penalty.
Can I compare several websites with DR Checker?
Yes. Start with an individual lookup, then open the comparison page for multiple domains from the same market. Evaluate each score alongside relevance, organic performance, and backlink quality.
What is DR4?
DR4 is the fourth version of Ahrefs' Domain Rating. Ahrefs announced it on November 5, 2026, made it available in its API the same day, and rolls it out in the standard Ahrefs interface on December 1, 2026. DR Checker shows DR4 next to DR3 when both are available, and the gap between them when the two were measured at about the same time.
What is the difference between DR4 and DR3?
Both are 0-100 scores built from backlinks. DR4 gives more weight to links from websites that get organic search traffic, counts links from a smaller, higher-quality pool of websites, rates each subdomain on its own links instead of passing down its root domain's score, and scores domains Ahrefs labels as spam much lower. Some well-known websites barely moved, while many subdomains on shared platforms such as Blogspot and GitHub Pages dropped sharply.
What is DR3?
DR3 is the name Ahrefs now gives the Domain Rating model it used before DR4: the score most tools have simply called DR. It looks at how many unique websites link to a domain, how strong those websites are, and how many other websites each of them links to, on a logarithmic 0-100 scale. Ahrefs keeps DR3 available in its API for a short time after the switch.
Can I compare a DR3 score with a DR4 score?
You can compare the two scores of the same domain to see how the new model rates it differently, which is what the DR4 vs DR3 leaderboard does. But the gap is not a change over time, and a DR4 of 40 does not mean the same as a DR3 of 40: Ahrefs has published no conversion. Rank websites against each other in one version, and label each number in a trend with its version.
