Domain Rating is Ahrefs' answer to link-strength measurement: a 0–100 score reflecting the quality and quantity of referring domains pointing at a site. If your workflow lives inside Ahrefs — or you evaluate vendors who quote DR — you need reliable ways to compare domain rating across dozens of domains without opening each one manually. This guide covers the tools that make DR comparison fast and the pitfalls that trip people up.
Quick Answer: Ahrefs Site Explorer is the native home of Domain Rating, supported by Ahrefs' free Website Authority Checker and batch analysis; Semrush Authority Score, Moz DA and Serpstat's equivalent metrics serve as cross-ecosystem reference points when you need a second opinion.
Keep one distinction in mind throughout: DR belongs to Ahrefs the way DA belongs to Moz. Any tool promising "DR" values is either pulling from Ahrefs or substituting its own scale.
What DR Measures — and What It Ignores
- Counted: unique referring domains and their strength, computed on a logarithmic curve so moving from DR 70 to 75 vastly outweighs moving from 5 to 10.
- Ignored: content quality, traffic, spam penalties and topical relevance — a gambling network and a university library can share a score.
- Relative: DR shifts when the wider web changes, so a completely flat profile can still lose points.
Comparison Tools at a Glance

| Ahrefs Batch Analysis | Comparing hundreds of URLs at once | No (paid plans) |
| Semrush Authority Score | Second-ecosystem cross-check | Limited free account |
| Moz Link Explorer (DA) | Alternative industry-standard scale | Yes, limited queries |
Platform Notes
Ahrefs Site Explorer
Beyond the headline DR number, Site Explorer shows the referring-domain growth chart behind it, so you can tell steady accumulation from a suspicious spike of purchased links. Comparing competitors side by side here grounds every DR conversation in actual link data. Subscription cost is the only real friction.
Ahrefs Website Authority Checker
The free checker returns DR, referring-domain counts and total links for any public URL — ideal for spot-checking a vendor claim or a guest post offer. It handles one domain at a time, which becomes tedious past ten or so.
Ahrefs Batch Analysis
Paste hundreds of prospect URLs and receive DR values in a single pass — the practical method for screening large outreach lists inside the Ahrefs ecosystem. Availability depends on your subscription tier, and bulk lookups count against your usage quota.
Semrush Authority Score
When a partner quotes numbers from a different toolbox, Semrush's composite score provides a fair translation layer. It correlates with DR broadly but blends traffic data, so divergences flag domains whose links outshine their actual visibility.
Moz Link Explorer
Moz's DA gives you the other scoreboard the industry reads. Checking borderline prospects on both scales catches one-sided inflation — a site at DR 60 but DA 25 warrants scrutiny before you invest outreach effort in it.
When Scores Disagree
Divergence between DR, DA and Authority Score is normal, not a bug. Each provider crawls independently and weights signals differently. Practical rule: use one scale for internal consistency, another as a fraud check, and settle final decisions with manual review of the linking sites themselves. A DR figure without context is a rumour with decimals attached.
Key Takeaways
- DR is Ahrefs' proprietary metric — authentic values come from Ahrefs products.
- Batch Analysis is the only sane way to compare DR across large lists.
- The logarithmic scale makes small numeric gaps at the high end enormous in practice.
- Cross-check borderline cases on a second metric before committing budget.
