Domain Authority (DA)
A 1–100 score from Moz that predicts how likely a domain is to rank in search. It is built from Moz’s own link index and a machine-learning model. Its scale is logarithmic, so climbing from 20 to 30 is far easier than 70 to 80.

Meet Domain Rating.
Translate Moz DA into Ahrefs DR, or back again. Calibrated on real websites checked in both tools, with a typical range alongside every estimate.
Moz DA ≈ Ahrefs DR
DA 72 converts to approximately DR 74. Most sites fall between DR 70 and 78.
Most sites at DA 72 fall between DR 70–78
DA and DR aren't a fixed exchange rate — real sites scatter, so the range is the honest answer, not the single number.

Domain Authority (DA) is a trademark of Moz; Domain Rating (DR) is a trademark of Ahrefs. High Jump Digital is not affiliated with or endorsed by either. This tool gives statistical estimates for guidance only.
Two scores, one question.
Domain Authority and Domain Rating are both trying to answer the same thing: how much authority does this website’s backlink profile carry? They come from different companies, built on different data, which is why a converter is useful.
Domain Rating (DR)
A 0–100 score from Ahrefs that rates the strength of a domain’s backlink profile, driven by the number and quality of referring domains in Ahrefs’ index. It is also logarithmic, so the top of the scale is the hardest to move.
How we built this converter.
There is no official formula between DA and DR, so we measured it. The conversion comes from a growing sample of real websites, each looked up in both tools on the same day, then reduced to a lookup.
Sample real sites
We collect real domains spread across the whole 0–100 range, so the low and middle of the scale are represented alongside larger sites.
Check both tools
Every site is looked up independently in Ahrefs for its DR and Moz for its DA, so each data point is a paired reading.
Median and range
At each level we take the median score as the headline number, plus the range most sites fall inside. Today that sample is 1162 verified websites, with a 0.77 correlation between the two scores. As we add more sites, the medians and ranges refine themselves.
Why the answer is a range.
Ten websites with the same DA can have different DR scores. That spread reflects differences in how each tool sees a site’s links. We show a best estimate for quick reference and the typical range underneath it. Use it to compare opportunities, rather than treating it as a guaranteed measurement.
Frequently asked questions.
Is DA 90 the same as DR 90?
Not exactly. In our current data a DA 90 site runs around DR 89, with most landing between DR 85 and 91. Even where the midpoints line up, Domain Authority (Moz) and Domain Rating (Ahrefs) are built on different link indexes and scaled differently, so any individual site can sit a few points either way. Treat them as closely related, not identical.
Which is better, Domain Authority or Domain Rating?
Neither is 'better' — they answer the same question with different data. Ahrefs (DR) and Moz (DA) crawl separate link graphs and normalise their scores in their own way. Use whichever score your tools report, and use this converter to translate between them when you need to compare like for like.
Why does the converter show a range instead of one exact number?
Because real websites scatter. Two sites with the same DA can have noticeably different DR. The single number is the median at that level; the range is where most sites actually fall — and it's the more honest answer.
How accurate is the DA to DR conversion?
It's calibrated on 1162 real websites, each independently checked in both Ahrefs and Moz, with a 0.77 correlation between the two scores. That makes it a strong estimate for ballpark comparisons — not a precise, guaranteed figure you'd put in a client report as fact.
Can I convert DR back to DA?
Yes — flip the toggle to 'Ahrefs DR → Moz DA'. One thing to note: a round trip won't always return your exact starting number, because each direction is fitted separately from the underlying data.
Want links that move these numbers?
DA and DR climb when quality sites link to you. That’s what our SEO and link-building work is built to do.
