What Is Domain Rating (DR)?
Abbreviation: DRAlso known as: Ahrefs DR, Ahrefs Domain Rating
Domain Rating (DR) is a proprietary Ahrefs metric, scored 0 to 100 on a logarithmic scale, that estimates the overall strength of a website's backlink profile relative to every other site in Ahrefs' index.

In plain English
DR is Ahrefs' answer to the question "how strong are this site's backlinks, overall?" A higher number means more, and stronger, referring domains point to the site. It says nothing about the site's actual content quality, traffic, or whether Google would rank it well — it is purely a link-popularity score, and Ahrefs itself is explicit that it should never be used as a standalone measure of quality or legitimacy.
Technical definition
DR is calculated using the same underlying logic as Ahrefs' page-level URL Rating (UR), but applied between domains rather than pages. It is driven by three inputs: the number of unique referring domains with at least one followed link to the target site, the DR of each of those linking domains, and how many other unique domains each linking domain also links out to (which dilutes the "DR equity" it can pass on). Only followed links from unique referring domains count — nofollow links and repeat links from the same domain do not add DR. The scale is logarithmic, so moving from DR 20 to DR 30 requires proportionally far less link strength than moving from DR 70 to DR 80.
Quick example
A new blog with 15 referring domains, mostly low-authority, might sit around DR 10-20. A well-established SaaS company with hundreds of referring domains including a few from major publications might sit at DR 70+. Getting one followed link from a DR 90 site that links out to only a few hundred other domains will move the needle far more than ten links from DR 20 sites.

Why Domain Rating matters
DR has become the de facto shorthand the link building industry uses to describe site strength, for better and worse.
It is the most widely quoted link metric in outreach
When a publisher, agency, or marketplace advertises a placement, DR is usually the first number mentioned. Understanding what it does and doesn't measure is essential to interpreting those pitches correctly.
It is not a Google ranking factor
DR is entirely an Ahrefs construct, built from Ahrefs' own crawl data. Google has never confirmed using anything resembling it, and a high-DR link on an irrelevant or low-traffic page can be worth less than a lower-DR link from a highly relevant, high-traffic one.
The logarithmic scale changes what "improvement" looks like
Going from DR 10 to DR 30 might take a handful of decent links. Going from DR 70 to DR 80 typically takes a sustained, long-term campaign — the same numeric jump represents a very different amount of underlying link equity.
It can shift even when your own links don't change
Because DR is calculated relative to every other site in Ahrefs' index, a site's DR can move up or down over time purely because other sites in the index gained or lost link strength.
It is easy to game in isolation
Low-quality link networks and PBNs can inflate DR relatively cheaply since the metric only measures the referring-domain graph, not content quality, traffic, or spam signals — which is exactly why Ahrefs pairs it with metrics like organic traffic and Ahrefs Rank in its own tools.
How it works
The three inputs Ahrefs combines to calculate a domain's DR.
- 1
1. Count unique referring domains with a followed link
Only domains sending at least one followed (dofollow) link count. Ten followed links from one domain count the same as one — DR only cares about the number of unique linking domains.
- 2
2. Weight by the DR of each linking domain
A followed link from a DR 90 site contributes far more than one from a DR 5 site. This is the same core logic as Google's original PageRank, applied at domain level rather than page level.
- 3
3. Divide by how many other domains the linking site links out to
A site that links out to very few other domains passes more "DR equity" per link than one that links out to hundreds of thousands, such as a major news homepage.
- 4
4. Normalise against the whole Ahrefs index
The final 0-100 score is calculated relative to every other domain Ahrefs has crawled, which is why DR can drift slightly over time even without any change to a site's own backlink profile.
Types and variations
DR is one of several competing site-authority metrics, each built differently.
Domain Authority (DA)
Moz's equivalent metric. Unlike DR, DA uses a machine-learning model trained against real Google search results in an attempt to predict ranking potential, not just measure link-graph strength.
Ahrefs Rank (AR)
A simple ordinal ranking of every domain in Ahrefs' index by backlink profile strength, rather than a 0-100 score.
URL Rating (UR)
The page-level equivalent of DR, measuring the backlink strength of a specific URL rather than the whole domain.
Trust Flow / Citation Flow
Majority's pair of metrics, splitting link quality (Trust) from link quantity (Citation) rather than combining both into a single score as DR does.
Best practices
Use DR as one input among several, never as a sole quality gate.
What to do
- Pair DR with organic traffic data to filter out link-farm domains that have artificially inflated DR but no real audience
- Check topical relevance alongside DR — a relevant DR 40 link often outperforms an irrelevant DR 70 one
- Look at referring domain growth trends, not just the current DR snapshot
- Use DR for rough triage and prioritisation, not as a hard cutoff for outreach targets
What to avoid
- Setting a rigid "DR 50+ only" policy without checking traffic or relevance
- Assuming DR correlates directly with Google ranking ability
- Comparing DR and DA as if they are the same scale — they are calculated completely differently and are not interchangeable
- Treating a high DR as proof a site is legitimate or free of manipulation
Common mistakes
Treating DR as a Google ranking signal
DR is an Ahrefs-only construct built from Ahrefs' own index. Google does not use it, publish anything equivalent, or factor it into rankings in any confirmed way.
Comparing DR directly to DA
Both scales run 0-100, which invites direct comparison, but the underlying calculations are unrelated. A DR 40 site and a DA 40 site can have very different actual link profiles.
Ignoring Ahrefs' own guidance
Ahrefs explicitly recommends against using DR as a standalone metric for judging site quality or legitimacy — advice frequently ignored by buyers and sellers in the link marketplace.
DR as an industry shorthand, not a quality guarantee
DR has effectively become the currency of the link-buying and outreach world, largely because it is easy to check and easy to compare. That convenience has a cost: a metric explicitly designed to measure link-graph strength gets treated, in practice, as a proxy for site quality, trustworthiness, and even ranking potential — none of which it was built to measure. The most reliable buyers in the space treat DR as a filter to narrow a list, then do the real evaluation on traffic, relevance, and content quality.
- DR measures link-graph strength only, not content quality or Google ranking ability
- The logarithmic scale means high-DR growth is disproportionately harder than low-DR growth
- DR can be inflated relatively cheaply through low-quality link networks
- Pairing DR with traffic and relevance data gives a far more reliable quality signal than DR alone
How iNet Ventures approaches domain rating
We report DR on every placement because clients expect it, but we never use it as the sole qualifying metric for a site we work with.
DR plus traffic, always together
Every site we vet is checked for real organic traffic alongside DR, filtering out link farms and PBNs that inflate DR without any genuine audience.
Relevance over raw score
A topically relevant DR 35 site is prioritised over an irrelevant DR 70 one, because relevance is a signal Google can actually verify, unlike DR itself.

Frequently asked questions
What is a good Domain Rating?
It depends entirely on your niche and competitors. A new site might realistically target DR 20-30, while an established brand competing on competitive terms might need DR 60+. Compare against the DR of sites actually ranking for your target keywords rather than chasing an arbitrary number.
Is Domain Rating the same as Domain Authority?
No. Both run on a 0-100 scale, but DR is Ahrefs' metric based purely on backlink-graph strength, while DA is Moz's machine-learning model trained to predict actual Google ranking potential. The same site can have very different DR and DA scores.
Does buying links from high-DR sites guarantee better rankings?
No. DR says nothing about a page's traffic, topical relevance, or whether Google considers the specific linking page trustworthy. A relevant link from a moderate-DR site with real traffic often outperforms an irrelevant link from a high-DR one.
Can Domain Rating go down?
Yes. DR can fall if a site loses referring domains, if sites linking to it lose their own DR, or simply because other domains in Ahrefs' index have grown stronger, since DR is calculated relative to the whole index.
