Every time I mention my site's numbers on X, someone replies with the same three letters: "what's DR?"
I get it. It's insider shorthand that sounds like it should be obvious and isn't. So here's the actual answer, once, in one place I can link to instead of retyping the same explanation in replies.
DR stands for Domain Rating. It's a metric built by Ahrefs, one of the two or three SEO tools everyone in this space ends up using, and it tries to answer one specific question: how strong is a website's backlink profile, relative to every other site Ahrefs has crawled?
It's a score from 0 to 100. Higher means a stronger backlink profile. That's it. That's the whole idea before you get into how it's actually computed.
Two things trip people up immediately. First, DR is not a Google metric. Google has never published anything called "Domain Rating," and it never will, because Google doesn't publish a single score for how strong your whole site is. Second, the scale is logarithmic, not linear. Going from DR 10 to DR 20 is a lot easier than going from DR 70 to DR 80. The higher you climb, the more it costs to climb further. A site rated 90 isn't twice as "strong" as a site rated 45. It's dramatically stronger.
The mechanics matter here, because most of the confusion about DR comes from people assuming it works like a popularity contest. It doesn't. It works a lot like the original PageRank algorithm, just calculated between whole domains instead of individual pages.
Roughly, here's what happens: Ahrefs looks at every domain with a followed (not nofollow) link pointing to yours. For each of those linking domains, it checks how many other domains that site links out to. Then it passes along a fraction of that domain's own authority, something like its own DR divided by however many places it links out to. Do that across every linking domain, run it through Ahrefs' formula, and you get a number.
A few specifics that actually change how you should think about your own numbers:
That last point is the one that surprises people the most. You can build a genuinely high DR using nothing but links from low-DR sites, as long as there are a lot of them from a lot of different domains. Ahrefs says this directly: you don't need big names, you need volume and variety.
No, and this is the misconception that actually matters if you're trying to grow anything.
Google ranks pages, not domains. Your homepage having a strong backlink profile doesn't automatically drag some unrelated blog post on your site up the results for an unrelated keyword. DR is a useful proxy for "this domain has authority Google's own systems probably also recognize in some form," but it's not the mechanism doing the work. The actual ranking factors are attached to the page, and to Google's own (unpublished, constantly shifting) sense of relevance and quality for that specific query.
What DR is actually good for is comparison, not causation. If you're looking at two sites in a similar niche and one sits at DR 15 and the other at DR 60, you can reasonably guess which one has an easier time ranking for competitive terms in that space, all else being close to equal. It's a signal about the terrain, not a lever you pull directly.
I'd go further: chasing DR as a goal in itself is exactly backwards. The sites with strong DR mostly got there by publishing things worth linking to, which is the same thing that also grows organic traffic. DR went up as a side effect. Optimizing for the side effect instead of the cause is how you end up buying junk links that inflate a number nobody outside your own dashboard cares about.
Close to nothing, and that's exactly what it should be.
This domain is a few weeks old as I'm writing this. A brand new domain starts at DR 0 because there's no backlink history to measure yet. Ahrefs doesn't give new sites a grace period or a starter score. You earn every point the same way: someone else's domain decides to link to yours.
The one useful thing I've learned from actually watching this instead of assuming: DR can move fast at the low end. A handful of genuinely good backlinks from decent domains can shift a brand new site by real amounts within weeks, precisely because the logarithmic scale is forgiving early and brutal later. The same handful of links that might move a DR 10 site to DR 20 wouldn't register at all on a site already sitting at DR 70.
So no, I'm not going to pretend I have an impressive number to report, because I don't. I'd rather tell you honestly that it's early and climbing slowly than make up a figure that sounds better. That's the same rule I've been trying to hold to since the first note on this site: a real "not much yet" beats a fake number every time.
A little, not obsessively.
It's a fine health check for your own backlink growth over time, and a fine way to size up a competitor at a glance. It's a genuinely bad thing to optimize for directly. If you find yourself buying link packages, joining link exchange schemes, or paying for placements on sites that exist only to sell links, you're playing the vanity-metric version of the game, and it tends to end with your site penalized rather than ranked.
The better version of the same instinct: write things specific and useful enough that other sites want to reference them without being asked. That's the whole strategy behind why distribution has been the actual hard part for every product I've shipped, not just this newsletter. Nobody links to something generic. People link to the post that answered their exact question, with a number or a detail they couldn't find explained anywhere else.
Which is more or less what this post is trying to be. If it worked, maybe it's the thing that gets linked to next time someone on X asks what DR means, instead of me typing the same reply for the fortieth time.
