Quick Start: How to Bulk Check Domains
What is the Domain Rating (DR) Metric?
Domain Rating (DR) is an authoritative link profile metric developed by Ahrefs. It illustrates the overall strength and weight of backlinks pointing to a target website. The metric is measured on a progressive logarithmic scale from 0 to 100.
The core factor in the calculation is donor analysis. The algorithm evaluates the volume of unique referring domains, their individual trust levels, and the proportion of outbound hyperlinks from each specific page. Importantly, only "dofollow" links transfer link juice; the "nofollow" attribute has virtually no impact on the final score.
DR is a highly dynamic value. Newly registered domains always start at zero and grow as they accumulate a high-quality backlink profile.

Where to Use a Bulk Authority Checker
Outreach & Link Building
Instantly filter out spammy sites and empty shells before purchasing permanent links. Focus only on trusted donors.
Guest Posting
Conduct a preliminary authority check on media platforms and blogs before submitting high-quality guest content.
Competitor Analysis
Compare your resource's metrics against search engine leaders to understand the required link building budget.
Comprehensive SEO Audit
Perform deep analysis of clients' link profiles to identify ranking drops and toxic inbound links.
Expired Domain Evaluation
Check expiring domain names at auctions. High authority scores guarantee a successful launch for PBN networks.
Dynamics Tracking
Regularly monitor your project's KPIs. Keep track of how new backlinks convert into measurable metric growth.
Comparing Key Metrics: Ahrefs DR vs. Moz DA
Both indices aim to evaluate a domain's weight, but they utilize independent crawlers and distinct mathematical models. Let's break down the key differences for accurate data interpretation.
| Feature | Domain Rating (Ahrefs) | Domain Authority (Moz) |
|---|---|---|
| Metric Creator | Ahrefs Team | Moz Team |
| Mathematical Model | Logarithmic (0-100) | Logarithmic (0-100) |
| Link Database | The world's largest commercial bot crawler | Proprietary Mozscape crawler |
| Primary Factors | Volume of unique referring domains and their trust | Complex signals including internal links and MozRank |
| Industry Popularity | De facto industry standard | High (especially in Western SEO) |
In modern link building realities, the majority of SEO specialists prefer to rely on DR. This is largely because the Ahrefs index updates significantly faster and boasts a much fresher database of indexed backlinks.
Deep Dive: How Domain Rating is Calculated
The architecture behind scoring is based on several strict rules:
1. Counting Referring Domains
The counter responds exclusively to unique websites. If Resource A places 100 links to your site, it still only counts as 1 vote for the DR calculation.
2. Source Weight
A backlink from a platform on the level of Wikipedia (DR 90+) can single-handedly push your rating up by dozens of points, whereas hundreds of links from low-quality directories will yield zero effect.
3. The Dilution Effect
The mathematical weight of a donor is divided by the number of its outbound Dofollow links. The fewer external links on a donor page, the more "link juice" flows to you.
4. Logarithmic Relativity
Raising your rating from 10 to 20 requires minimal effort. However, crossing the threshold from 70 to 80 demands attracting hundreds of the world's most powerful, trusted links.
Why Can Your Rating Drop Suddenly?
A drop occurs if your key donors remove backlinks, if the donors themselves lose their trust, or if there is an Ahrefs crawler update. A decline is also possible if competitors are building their link profile much more aggressively, shifting the 100-point benchmark.
