The same website can show a high DR in Ahrefs and a much lower DA in Moz, leaving many SEO professionals wondering which score matters more. The confusion is understandable, especially when these metrics are used to assess websites for backlinks, competitor research, or overall SEO performance. However, treating the two scores as interchangeable can lead to the wrong conclusion. DR and DA are built differently, so a higher number in one does not automatically make it more valuable than the other. Understanding what each metric measures and how to interpret the difference can help you make more informed SEO decisions.
DR and DA Measure Different Things
What Domain Rating Measures
Domain Rating (DR) is Ahrefs’ metric for evaluating the strength of a website’s backlink profile. It uses a 0–100 scale and considers the quality and quantity of referring domains, along with how those domains distribute their link equity. The score is relative, so it is more useful for comparing backlink profiles within the Ahrefs ecosystem than treating a particular number as an absolute measure of website quality.
What Domain Authority Measures
Domain Authority (DA) is Moz’s predictive metric for estimating how likely a domain is to rank in search results. Like DR, it uses a 1–100 scale, but Moz generates its score using its own data and methodology. As a result, interpret a DA score within Moz rather than directly comparing it with an Ahrefs DR score.
Why the Same Website Can Have High DR and Low DA
A difference between DR and DA doesn’t necessarily mean one tool measured the website incorrectly. The scores can vary because Ahrefs and Moz use their own datasets, link indexes, and scoring methodologies. They also evaluate those data differently when producing their respective metrics.
This is why a website might show a DR of 70 but a DA of 40, for example. You should not treat the two numbers as conflicting versions of the same score. Each one reflects how that website appears within a particular platform’s measurement system.
This also means there is no reliable conversion between the two. A DR of 70 cannot be assumed to correspond to a particular DA, and comparing the numbers directly can make a website appear stronger or weaker than it actually is. A more useful approach is to compare websites using the same metric and tool, then examine the underlying factors that matter for the SEO decision.

So, Which Score Should You Trust?
Neither should be treated as the definitive measure of a website’s SEO strength. If you’re comparing several sites in Ahrefs, DR can provide a consistent basis for comparing their backlink profiles. The same applies to Moz’s DA.
The important point is to compare like with like. A DR of 60 should be compared with other DR scores, while a DA of 60 should be compared with other DA scores. Putting the two numbers side by side and choosing the higher one does not tell you which website has the stronger SEO profile.
For backlink or competitor analysis, treat the score as a starting point. The site’s relevance, backlink profile, organic visibility, and the quality of the specific opportunity can provide much more useful context.
What Matters When a High DR and High DA Tell Different Stories
Topical Relevance
A website should be relevant to the subject you are evaluating. A strong score from a site that has little connection to your industry or audience may be less useful than a lower-scoring site that consistently publishes relevant content.
Backlink Quality and Referring Domains
Look beyond the overall score and examine where the site’s links come from. A backlink profile with relevant, credible referring domains provides more useful context than a large number of links alone.
Organic Search Visibility
Check whether the website actually appears in search results and attracts organic traffic. A high third-party score does not automatically indicate strong current visibility for relevant queries.
Content and Website Quality
Review the site’s content before treating its score as a quality signal. Consistently useful, relevant content provides more context about the website than a single metric can.
The Actual Link Opportunity
If you’re evaluating a potential backlink, examine the specific page where the link would appear. Its relevance, placement, surrounding content, and purpose can matter more than the domain-level score alone.
What DR and DA Cannot Tell You?
A strong score can help you compare websites, but it doesn’t provide a complete picture of how a site performs in search. Neither metric is a Google ranking factor, and neither one guarantees that a website will rank well or that a backlink from it will improve rankings.
A high score also doesn’t automatically mean a site is trustworthy, topically relevant, or worth pursuing for a link. Conversely, a lower score does not by itself prove that a site is poor or spammy. Treat these metrics as diagnostic signals, not a final judgment on a website.
How to Use DR and DA When Evaluating a Website
Use these metrics as an initial filter, not as the final basis for choosing a website. If two potential sites have different scores, compare each one within the same measurement system first, then examine the factors behind those numbers.
A practical evaluation can focus on five questions:
- Is the site relevant? Check whether its content and audience match your topic or industry.
- Does it have a credible backlink profile? Look at the quality and relevance of its referring domains, not just the total count.
- Does it have organic visibility? Review whether the site ranks for relevant searches and attracts organic traffic.
- Is the content genuinely useful? A strong metric does not compensate for thin, outdated, or poorly maintained content.
- Does the specific link opportunity make sense? Consider the page, placement, surrounding content, and the proposed link’s relevance.
This approach puts DR and DA in their proper role: useful comparison signals that help guide further analysis, rather than scores that make the decision for you.
Conclusion
A high DR is not inherently better than a high DA. The two metrics come from different platforms, use different data, and rely on different methodologies, so you shouldn’t treat their scores as equivalent. Use DR or DA to benchmark websites within the same tool, then look at relevance, backlink quality, organic visibility, content, and the specific link opportunity before making an SEO decision.
