Ask whether domain rating matters and you will get two useless answers. One camp says it is everything. The other says it is a vanity metric invented to sell subscriptions.
Both are wrong in the same way: they treat DR as a verdict rather than as a measurement of something specific. It measures backlink strength. Whether that matters depends entirely on what you are about to do with the number.
What domain rating actually measures
DR is a logarithmic score from 0 to 100 derived from the quantity and strength of other domains linking to yours. Nothing else feeds it — not traffic, not content quality, not age, not revenue.
The logarithmic scale is the part people misread. Moving from DR 20 to DR 30 is a modest amount of work. Moving from DR 70 to DR 80 is a different category of effort entirely, and the gap between DR 78 and DR 82 means almost nothing.
It is not a Google ranking factor
This is not in dispute. DR is Ahrefs’ metric and Domain Authority is Moz’s; Google uses neither, and has never claimed to.
The correlations that do exist are real but modest. Ahrefs’ own analysis across 218,713 domains found DR and keyword rankings correlate — while being clear that correlation is not causation. Independent analyses have put the coefficient somewhere around 0.13 to 0.16, which is a small positive relationship, not a lever.
The reason a correlation shows up at all is unsurprising. Sites with strong link profiles tend to be sites doing many other things well, and some of those other things genuinely are ranking factors.
Where DR is genuinely useful
The metric earns its place in three jobs, and all three are comparative rather than absolute.
| Use it for | Why it works | Do not use it for | Why it fails |
|---|---|---|---|
| Spotting sites ranking above their link profile | A low DR beside high traffic is a genuine anomaly worth investigating | Judging whether a page is good | DR says nothing about content at all |
| Sizing the link gap in a SERP | Shows roughly how much authority the incumbents carry | Predicting your position | Correlation with rank is around 0.14 |
| Filtering a large list down to a shortlist | Cheap, universally available, good enough to sort by | Pricing a guest post | Rewards link volume, not readership |
The mistake that costs the most
Sorting link prospects by DR is the single most expensive misuse of the metric, and it is close to universal. A DR 70 domain with 400 monthly visitors is worth less than a DR 25 domain with 60,000 engaged readers, on almost any measure you care about.
Sort by traffic instead and the shortlist reorders completely. We made that argument at length in our piece on building guest post lists from traffic data, and it remains the fastest improvement most link builders can make.
Reading a low DR correctly
A low DR on a site with serious traffic is not a weakness. It is a signal that the SERP it competes in is not being defended by link equity.
That is the whole basis of finding low-DR, high-traffic sites and working out what they did. When several of those sites cluster in one niche, the niche is telling you something useful about its own softness.
The reverse reading is just as useful. A SERP where every site above 20,000 visits also sits above DR 60 is one where you will need links, regardless of how good your content is.
Used this way, DR stops being a scoreboard and becomes a diagnostic. The interesting number is never the score itself but the distance between it and the traffic sitting next to it. A wide gap in either direction is information; the score alone is not.
It is the same logic behind identifying high traffic, low competition niches: count how many low-authority sites are winning, and the competitive shape of the whole category becomes visible without reading a single article in it.
What actually moves the number
Because DR is built from referring domains, only one thing raises it: links from domains that are not already linking to you. A second link from a site that already points at you adds almost nothing to the score.
That has an awkward consequence. The cheapest way to move DR is to acquire many links from many weak-but-distinct domains, which is precisely the activity that produces no traffic and carries real risk. The metric can be gamed, and the gap between a gamed DR and a site’s actual standing is usually obvious the moment you look at its traffic.
This is also why DR is slow to fall. Links persist, so a site that stopped publishing three years ago can hold a respectable score long after its rankings have gone. When you see a high DR beside flat or declining traffic, you are almost always looking at a site living on past work — the same pattern worth checking when you read a core update and try to work out who actually won.
DR versus domain authority
They measure the same broad thing with different crawls and different maths, on the same 0–100 logarithmic scale. Neither is more “correct”.
What matters is consistency: pick one and use it throughout a comparison. Mixing them within a single shortlist produces rankings that reflect index differences rather than anything about the sites.
How much should it weigh in a decision?
Treat DR as one column, never as the sort order. It is a fast, free-ish way to understand the shape of a competitive field, and a poor way to decide anything on its own.
When it disagrees with traffic, trust traffic. When it disagrees with what you can see on the page, trust the page. And when the two sit far apart in the same row, stop and look properly — that gap is usually where the interesting sites are.
Frequently asked questions
Is domain rating a Google ranking factor?
No. Domain rating is a third-party metric from Ahrefs and domain authority is Moz’s equivalent. Google uses neither. Published correlations between these scores and actual rankings sit around 0.13 to 0.16, which is a small positive relationship rather than evidence of a direct effect.
What is a good domain rating?
There is no universal threshold, because the scale is logarithmic and only meaningful relative to the SERP you are competing in. DR 30 is strong in a niche where the leaders sit at DR 35 and irrelevant in one where they sit at DR 80. Always read it against the competition, never against a benchmark.
Does domain rating affect ranking directly?
Not directly. Improving DR generally means acquiring links, and links do influence rankings, so the score tends to move alongside results. But raising DR through links that bring no relevance or traffic rarely moves positions, which is why the two can drift apart.
Should I use DR to choose guest post targets?
Only as a secondary filter. Sort candidates by organic traffic first, then use DR to break ties. A high-DR site with almost no readership passes little real value, and those sites are common in marketplaces precisely because the metric is easy to inflate.
The takeaway Domain rating measures backlink strength and nothing else. Use it to size a competitive field and to spot sites outperforming their link profile — never as the column you sort by, and never as a substitute for looking at traffic.
