Domain Rating (DR) is Ahrefs’ score, from 0 to 100, for the strength of a website’s backlink profile. It is calculated from the number of followed referring domains pointing at a site, the DR of those domains and how many other sites each of them links to. Ahrefs describes the scale as logarithmic: the gap between DR 75 and 76 is much bigger than the gap between DR 20 and 21.
Does it still matter? Yes, as a filter. No, as a goal. DR is the fastest way to screen potential link sources and a fair proxy for the backlink strength Google does evaluate. But Google has no domain authority metric of its own, DR can be inflated by link networks, and Ahrefs’ own research found DR tracks brand visibility in AI Overviews only about half as closely as brand mentions do. Treat it as the first check, never the only one.
Use Domain Rating to shortlist sites, then confirm with organic traffic, editorial standards and how often the site is already cited by AI assistants.
What is Domain Rating, and how is it calculated?
Ahrefs publishes the inputs but not the formula. According to the Ahrefs glossary, DR reflects three things: how many unique domains link to the site, the DR of those domains, and how many sites each of them links to in turn. A DR 80 site that links out to 50 domains passes more than one that links to 5,000.
Three details are worth knowing. First, nofollow links (links carrying a rel=“nofollow” attribute that asks search engines not to pass credit) do not pass DR, so only followed links, often called dofollow, move it. Second, the higher a site’s DR, the harder it is to raise, so ten points near the top of the scale take far more work than ten near the bottom. Third, DR is a site-wide score: every page on a site shares it, from the homepage to a forgotten archive page.
How does DR compare with Authority Score and Domain Authority?
Three tools, three scores, three methods. They are often treated as interchangeable. They are not: a site can score DR 65, Authority Score 40 and DA 55 at once without anything being wrong.
| Domain Rating (DR) | Authority Score (AS) | Domain Authority (DA) | |
|---|---|---|---|
| Who makes it | Ahrefs | Semrush | Moz |
| What it measures | Strength of the backlink profile: followed referring domains, their DR, and their outbound link counts | A compound of link power, estimated organic traffic and spam factors such as an imbalance between links and traffic | A machine-learning prediction of how likely a site is to rank, built mainly from Moz’s link data |
| Scale | 0 to 100 | 1 to 100 | 1 to 100 |
| Data source | Ahrefs’ link index | Semrush’s link index plus its traffic estimates | Moz’s link index |
| What it misses | Traffic, relevance, content quality, whether the links were bought | Topical relevance, editorial quality; traffic is a Semrush estimate, not analytics data | Traffic, relevance; the score is relative, so it can fall when other sites gain links |
The practical consequence: compare sites within one tool only. A DR 60 site is not “better” than an AS 45 site; the numbers come from different indexes and different formulas. Semrush’s Authority Score is the only one of the three that folds in organic traffic and spam checks, which in our experience makes it harder to game but less of a pure link metric. Moz describes Domain Authority as a comparative metric rather than an absolute one, and the same applies to all three.
Does Google use Domain Rating?
No. Google’s John Mueller has said publicly that Google does not use a domain authority signal, and Search Engine Journal covered his comments in 2018. Moz says the same of its own score: Domain Authority is not a Google ranking factor. The answer applies equally to DR and Authority Score. All three are third-party estimates built from each vendor’s own crawl, not from Google’s data.
That does not make DR useless. Google does evaluate the links pointing at a page and the sites they come from, and DR is built from the same raw material. The mistake is to optimize for the number itself, which is what happens when agencies sell “DR 70 guest posts” on sites nobody reads.
Why is DR a filter rather than a goal?
Because DR can be bought. A site owner can push a new domain to DR 50 or above with links from a private blog network, a redirected expired domain or link swaps with hundreds of other sellers. None of that creates an audience. The result is a site with a respectable DR, almost no organic traffic and a publishing calendar made entirely of paid posts.
This is why our own vetting bar pairs DR 50+ with 10,000 or more monthly organic visits, steady or growing, with most of that traffic from the target market. Traffic is much harder to fake than links. The nine checks we run before buying a link treat DR as the first of them, not the last.
DR also says nothing about relevance. A DR 75 link from a cooking site to a payroll software page carries less weight than a DR 45 link from a trade publication payroll buyers actually read. Topical fit is a vetting criterion in its own right, and DR cannot measure it.
Pricing still tiers by DR, and ours does too: guest posts at $250 for DR 50 to 69, $280 for DR 70 to 79 and $320 for DR 80+. The tiers are fair because, all else being equal, higher-DR sites are harder to get into. The link building cost guide explains why the cheapest DR 70 placement on the market is usually the worst value on it.
Does Domain Rating predict AI citations?
Only weakly. Ahrefs’ 2025 study of 75,000 brands and their visibility in Google AI Overviews is one of the largest public datasets on this question. The factor most strongly associated with being mentioned was branded web mentions, with a Spearman correlation of 0.664. Branded anchors came next at 0.527 and branded search volume at 0.392. Domain Rating followed at 0.326, about half the strength of web mentions, and Ahrefs described link metrics as moderate to weak correlates. These are correlations, not causes, so none of them is a lever you can pull on its own.
The pattern makes sense once you consider how AI search tools typically build answers: they retrieve pages that discuss a topic, then name the brands those pages mention. Profound’s analysis of 11.8 billion AI citation data points (2026) found that brand websites account for 57 percent of AI citations globally, which means about 43 percent go to third-party pages such as media, communities and institutions; on ChatGPT, brand websites fall to 47 percent, so over half of citations there are third-party (Profound, 2026, summarized by WARC). Your own DR does not decide whether a trade publication’s “best payroll tools” article names you. Being in that article does.
We see the same thing in our own work. In engagements we track, brands we have placed in third-party articles, guest posts and listicles have seen AI citations rise by roughly 70 to 80 percent on the prompts where those articles are cited. In our experience, the host site’s DR mattered less than whether ChatGPT, Perplexity, Gemini, Claude and Google AI Mode already quoted it, which is why AI citation frequency is now the ninth check in our vetting process. The reasoning is laid out in our guide to why third-party articles decide which brands AI recommends.
How should you use DR in practice?
Use it in this order, whether you are a fintech, a manufacturer, a law firm or a consumer app.
- Screen with DR. Set a floor (we use 50) and discard everything below it. This takes seconds and removes most of the noise.
- Confirm with organic traffic. Require 10,000 or more monthly visits, steady or growing, mostly from the market you sell to.
- Check for a price list. A public “write for us” page or sponsored-post rate card means the site sells to anyone, and Google’s spam policies treat links bought to pass ranking credit as link spam.
- Read the outbound links. Any links to casino, CBD or essay-writing sites, and you walk away, whatever the DR.
- Check AI citation frequency. Run a handful of prompts in ChatGPT, Perplexity and Google AI Mode on the site’s core topics and see whether it gets cited. Our free LLM visibility checker is a quick way to start.
For your own site, stop watching DR weekly. Track the keywords you rank for, the traffic they bring, the third-party pages that mention your brand, and how often AI assistants name you for the prompts your buyers type. DR rises as a side effect of real coverage. Chasing it directly produces links that pass a score and nothing else.
How Model Marketing helps
We build links the way this post recommends: DR is the first filter and never the last. Every site we place on passes all nine of our vetting checks, including the AI citation check, and a second reviewer reads every article and link before it goes live. The bar is the same whether the client sells software, financial services, consumer apps or manufactured goods.
Guest posts are priced at $250, $280 and $320 by DR tier and niche link insertions at $200, $230 and $260 to $300, with no retainer, billing per live link twice a month, month to month on 30 days’ notice, and free replacement of any link removed within 12 months. Details are on the link building service page and the pricing page. If the real question is why your brand is missing from AI answers, our AEO/GEO (AI search visibility) work starts with a two-week audit of where and how often you are cited.
