You'll hear people throw this number around like it's a credit score for websites. "Our DA is 45." "We need links from DA 60+ sites." And honestly, it's useful shorthand. But it's also widely misunderstood.
What Domain Authority Actually Measures
Domain Authority (DA) is a metric created by Moz that predicts how likely a website is to rank in search results. It runs on a scale of 1 to 100. Higher scores mean stronger ranking potential.
Here's what catches people off guard: DA is not a Google metric. Google doesn't use it, doesn't acknowledge it, doesn't factor it into rankings. It's a third-party prediction tool built by analyzing link profiles, root domains, and hundreds of other signals. Moz created it. Ahrefs has their own version called Domain Rating. Semrush calls theirs Authority Score. Different tools, different formulas, different numbers for the same site.
The Number Everyone Obsesses Over (and Shouldn't)
DA is a comparative metric, not an absolute one. A DA of 35 doesn't mean your site is "bad." It means your site has less predicted ranking power than a DA 60 site. That's it.
Where teams go wrong is treating DA as a KPI to optimize directly. You can't. There's no "increase DA" button. The score reflects the strength of your backlink profile, the age of your domain, content quality, and dozens of other factors. Improving those things moves the needle over time. Chasing the number itself is like checking your weight every hour. Pointless, and probably stressful.
The real value of DA is competitive analysis. Comparing your score against sites that rank for the keywords you're targeting tells you roughly how hard the fight will be. If every result on page one has a DA above 70 and you're sitting at 20, you need a different angle. Long-tail keywords, niche content, patience.
How to Move the Needle
Earn quality backlinks. This is the single biggest lever. Links from relevant, high-authority sites push your DA up over time. Links from junk sites do the opposite.
Clean up your link profile. If you've got toxic or spammy links pointing to you, disavow them. A messy backlink profile drags the whole score down.
Publish consistently. Sites that produce valuable, link-worthy content naturally attract referring domains. One viral piece helps, but steady output builds the kind of profile that compounds.
And stop refreshing the score every week. DA moves slowly. Think quarters, not days.
