DA vs. DR: Let's Settle This Argument Once and for All

Alright, let's have a real talk. You’re in the SEO world, trying to do everything right. You start tracking your Domain Authority (DA), and just when you feel like you’re getting somewhere, you hear someone talking about "DR."
And the confusion kicks in. Is it a replacement? Is it better? Are you behind the curve?
Relax. This is the classic DA vs DR debate, and honestly, most people just nod along without really knowing the difference. They are not the same thing, not by a long shot. And understanding their core differences is what separates the amateurs from the pros.
So, let's settle this. We're going to break down Domain Authority vs Domain Rating in plain English, so you know exactly what they are, what they’re for, and which one you should actually be paying attention to.
(If the whole concept of authority is new to you, you might want to read our foundational Ultimate Guide to Domain & Page Authority first. It’s the perfect primer.)
First Up: The Old Guard, Moz's Domain Authority (DA)
If you've used any website authority checker in the past ten years, you've seen Moz DA. It's the original, the one everyone knows.
Moz created DA to answer a business-focused question: "How likely is this website to rank on Google?"
That's it. It’s a predictive score. Think of it as an all-around health check. It looks at your links, sure, but it also uses a machine-learning system to compare your site to the thousands of sites that are actually ranking high on Google. It’s trying to find a correlation, a pattern. It’s not just counting your links; it's weighing your entire profile against the current winners.
Because of this, DA is a fantastic, high-level metric for gauging your overall SEO competitiveness.
Next: The Purist's Choice, Ahrefs' Domain Rating (DR)
In the other corner is Ahrefs DR. Ahrefs is a beast when it comes to backlink data, and their metric reflects that singular focus.
DR was built to answer a much more technical and direct question: "How powerful is this website's backlink profile?"
That's the whole game for DR. It doesn't care about anything else. It’s a raw measure of link-based horsepower. Its calculation is more straightforward: it looks at the quality and quantity of unique websites linking to you. A link from a high-DR site passes more "juice." Simple as that.
The one major thing to know is that a domain rating checker based on the Ahrefs model only looks at "dofollow" links. If a link has a "nofollow" tag (telling Google not to pass authority), DR ignores it completely. It's a purist's metric, built for technical link builders who care only about raw link equity.
The Showdown: So What's the Real Difference?
Look, you can read technical articles all day, but here's the bottom line difference between Domain Authority vs Domain Rating:
- DA is trying to predict a result (ranking on Google).
- DR is trying to measure a raw ingredient (backlink strength).
It's like the difference between a decathlete and a powerlifter.
The decathlete (DA) has to be good at a bunch of different things to win. Their final score is a reflection of their overall athletic ability. The powerlifter (DR) only cares about one thing: how much weight can they lift? Their score is a measure of pure, raw strength.
One isn't inherently "better," they're just training for different events.
The Final Answer: Which SEO Metric is Best?
I'm going to give you a straight answer: stop overthinking it.
There is no single "best" metric. The question "which SEO metric is best?" is the wrong one to ask. The right question is, "Which metric is most useful for the task I'm doing right now?"
- For your monthly reports, strategic planning, and competitor benchmarking? Use DA. It gives you that high-level, "how are we doing on Google?" snapshot that a boss or a client can understand.
- For a specific, granular link-building campaign where you're vetting hundreds of potential sites? DR can be very useful for its pure, technical focus.
But here's the most important piece of advice you'll get today:
The biggest mistake in the DA vs DR debate is comparing your DA to a competitor's DR. It's utterly meaningless. It's like comparing your weight in pounds to their weight in kilograms.
The name of the game is consistency. Pick one metric, track it with a reliable tool, and measure yourself against your competitors using the exact same metric. Is the gap closing? Are you trending up? That's all that matters.
Chasing a score is a fool's errand. Building a trend line is a strategy.
