Domain Rating: what it is, and what actually moves it

Domain Rating (DR) is Ahrefs’ score for the strength of a whole domain’s backlink profile, on a logarithmic 0–100 scale. It is domain-level, not page-level: Ahrefs publishes a separate URL Rating (UR) for individual pages, and the two move independently.

The important word is backlink. DR is not a quality score, a traffic estimate, or a judgement about your product. It is a measurement of one thing: who links to you. A site with the best documentation in its category and no inbound links sits at DR 0, and that is the metric working as designed rather than failing.

Two inputs: the number of unique referring domains pointing at you, and the DR of each of those domains. A link from a DR 90 site is worth many times a link from a DR 10 site, and a hundred links from the same domain are worth roughly what one link from it is worth.

That second point is the one that changes behaviour. Founders track total backlinks because it is the bigger, nicer number, then wonder why 800 links produced almost no movement. If 780 of them came from twelve sites, the metric saw twelve.

The logarithmic scale, in practical terms

Each ten-point step costs several times what the previous one did. Getting from DR 0 to DR 20 is a matter of a few dozen referring domains and can happen in weeks. Getting from DR 50 to DR 60 is a different category of work — hundreds of domains, most of which have to be earned rather than submitted to.

This is also why the early gains feel misleadingly easy. A product that hits DR 25 in its first two months has not solved link building; it has collected the cheap half of the curve.

What DR cannot see

Your content, your on-page optimisation, your Core Web Vitals, your traffic, your revenue, your social following, and topical relevance. That last omission matters: a link from an unrelated DR 60 blog counts the same to DR as a link from the DR 60 leader in your exact category, while Google treats them very differently.

There is no universal number, because DR is a rank within an index rather than a measurement against a fixed standard. The only comparison that means anything is against the sites currently ranking for the keywords you want.

The table below is rough orientation, not a study. We have not surveyed a statistically meaningful sample and neither has anyone else publishing tables like this; treat it as a sense of the shape of the curve.

A product launched this quarter sitting in single digits is normal and not a problem to solve. The useful question is never “is my DR good?” but “what is the DR of the ten results already ranking for the phrase I am writing for?” If they are all 50+, content quality alone will not get you onto that page, and you should pick a longer phrase while you build links.

Both run 0–100 and both are third-party inventions. They disagree constantly, because they are computed from different crawls of the web with different rules.

Pick one and stay with it. The absolute value matters far less than the direction of travel, and mixing the two inside a single comparison produces decisions that look data-driven while being arbitrary — a site can genuinely be DR 55 and DA 32 at the same time. When someone in the startup world says “we’re at 45”, they mean DR.

This is the most common surprise, and usually it is not about you.

• Recalibration. DR is a position within Ahrefs’ index. When other domains gain referring domains faster than you do, you slide without losing anything.
• Lost referring domains. A linking page went offline, was rewritten, or the site removed the link. This is the one worth acting on — Ahrefs’ lost-links report names them.
• Revaluation of the sites linking to you. If a directory that links to you drops in DR, the value it passes drops with it.
• Consolidation. Two sites that linked to you separately merged or now redirect to one domain, so your unique count fell by one.

One to three points is noise; do not investigate it. Five or more points in a short window is worth thirty minutes with the lost-links report.

Only one thing: more unique referring domains, weighted by their own strength. Ordered by how quickly they realistically produce a domain you did not have before:

• Directory and marketplace listings. The fastest because each accepted listing is a new referring domain, and the work is bounded — see the next section for which ones we could verify.
• Integration and partner pages. If your product integrates with anything, that vendor’s marketplace or integrations page usually links out. These tend to be strong domains, and the link lasts as long as the integration does.
• Something worth citing. A tool, a dataset, a benchmark — anything a writer needs to reference in order to make their own point. This is the only category that compounds without further effort from you.
• Unlinked mention reclamation. Sites already writing your product name without linking are the highest-conversion outreach you will ever do, because there is no pitch to make.
• Guest writing in your actual category. Slow, and worth it only where the publication is relevant. One link from the leading blog in your niche beats twenty from unrelated DR 40 sites, for rankings if not for DR.

We maintain 108 launch directories and check each one by hand for whether its outbound link is actually followed, rather than copying the claim from another list. As of the last sweep: 37 were confirmed dofollow, 2 were confirmed nofollow, and 69 we could not verify either way.

That last number is the honest part, and most lists do not publish it. A directory whose link type we could not confirm is one where we could not find a live listing to inspect — not evidence that it is bad, and not evidence that it works. We label it unknown and let you decide, which is different from the “100+ dofollow directories” claim that nobody backs with a date and a URL.

Of the confirmed ones, 31 ask for nothing back — no reciprocal badge on your own site. Those are the cheapest new referring domains available to a product that launched last week.

Two things to keep in mind before submitting to everything. First, a nofollow listing still counts as a referring domain in Ahrefs’ index, so it can move DR while passing none of the ranking signal you submitted for — the metric and the outcome diverge here. Second, relevance is invisible to DR but not to Google, so a directory in your actual category is worth more than a general one with a higher score.

• Buying packages of links. “500 backlinks for $50” means a handful of low-DR sites linking many times each. The metric barely notices, and the footprint is the one Google is explicitly looking for.
• Counting backlinks instead of referring domains. The number that moves DR is the count of distinct sites. Celebrating a fourth link from the same publication is celebrating nothing.
• Ignoring relevance because DR ignores it. Optimising for the metric rather than the rankings the metric is a proxy for. The cooking blog link raises your DR and does nothing for your developer-tool keywords.
• Checking once and stopping. DR moves on a scale of months. Track referring domains monthly instead — if that number climbs and DR does not, your new links are coming from weak domains, which is diagnostic rather than mysterious.

The checker above calls api.ahrefs.com/v3/public/domain-rating-free directly, server-side, with a key we hold — it is Ahrefs’ own documented public endpoint, not a scrape of their website. What comes back is exactly the number Ahrefs’ own Website Authority Checker would give you, because it is the same underlying data.

That distinction matters because most of the free “DR checkers” scattered across other directory sites call an undocumented Ahrefs endpoint — one meant for their own website, not for third parties. It moves without notice, and when it does those pages return a network error while still claiming to be “powered by the official Ahrefs API”. This one is built on the endpoint Ahrefs publishes for exactly this use, which is a different reliability story, not a guarantee against the same fate.
