DA vs DR: What's the Difference?
Move the sliders to see what a given Domain Authority or Domain Rating score roughly indicates, and why the two rarely land on the same number for the same site.
A solid, established site by most standards — often a small-to-mid publication or a well-run niche authority.

The short version
Domain Authority (Moz) and Domain Rating (Ahrefs) both try to estimate how strong a site's backlink profile is, on a 0-100 logarithmic scale. Neither is published or endorsed by Google, and both can be inflated by exactly the kind of low-quality links a careful buyer is trying to avoid — which is why we treat them as a first filter, not a final answer, in how to vet a guest post site before you buy.
FAQs
Is DA or DR more accurate?
Neither — both are third-party estimates from Moz and Ahrefs respectively, calculated from each tool's own backlink index using its own methodology. Google doesn't use either metric directly, and neither is a substitute for checking real traffic and content quality.
Why do DA and DR sometimes differ a lot for the same site?
The two tools crawl and index the web differently, so they see different (and differently-sized) sets of backlinks pointing to any given domain. A site with more links visible to Ahrefs' crawler than Moz's, for example, may show a notably higher DR than DA.
Should I ignore DA and DR completely?
No — they're still useful as a fast first filter to rule out obviously weak, unlinked domains. Just don't treat either number as a final verdict on a site's quality.
