Domain Authority vs Domain Rating: Which SEO Metric Should You Trust?
Domain Authority (DA) and Domain Rating (DR) are third-party research metrics. They are not interchangeable with Google's PageRank or a score supplied by Google. A difference between the two does not diagnose a technical SEO problem.

Domain Authority (DA) and Domain Rating (DR) are third-party research metrics. They are not interchangeable with Google's PageRank or a score supplied by Google. A difference between the two does not diagnose a technical SEO problem.
What the metrics represent
| Metric | Provider | Intended use |
|---|---|---|
| DA | Moz | Comparative estimate of ranking potential |
| DR | Ahrefs | Relative strength of a domain's backlink profile |
| UR | Ahrefs | Link strength at page level |
The providers use different indexes and models. Scores therefore need not agree, and their refresh schedules should not be assumed to be identical. Compare like-for-like snapshots from the same provider rather than subtracting DA from DR.
What a high score does not prove
Neither score establishes content accuracy, an engaged audience, a clean history, or the value Google assigns to a specific link. A small specialist publication can serve your audience well despite a modest score. A high-metric domain can still publish irrelevant or manipulative material.
A low DA alongside high DR does not, by itself, prove weak on-page SEO. Inspect the actual pages, indexability, search performance, and sources of links. For the underlying DR model, see Domain Rating explained.
A practical comparison workflow
- Choose comparable competitors serving the same audience and search intent.
- Record the tool, date, domain scope, and score.
- Review a sample of referring pages and the destination pages they reference.
- Check first-party search and conversion data where you have permission. Third-party traffic estimates are not measured visits.
- Decide on a specific improvement: clearer content, a repaired link, or a useful resource for readers.
Do not purchase links simply to increase a score. Content quality does not exempt paid placements from link policies. If you are evaluating a publisher, use the guest-post site checklist alongside these metrics.
Measure outcomes beyond authority scores
Record qualified enquiries, organic clicks, referral visits, and changes to important landing pages. DA or DR can provide context, but neither is a business outcome or a guarantee of rankings. There is no universal DA/DR threshold that a Thai website must reach.

Is Moz DA the same as Ahrefs DR?
No. DA is Moz's comparative metric and DR is Ahrefs' backlink-profile metric. Their datasets and calculations differ, so the same numeric value does not mean the same thing.
Which metric is better for link building?
DR is useful for comparing backlink profiles inside Ahrefs; DA provides a separate comparison inside Moz. Neither replaces reading the linking page, checking relevance and assessing the audience.
Can I improve my DA and DR simultaneously?
Earning useful references may change both scores, but each provider updates its own model and index. Improving titles or site speed is worthwhile for users; it does not guarantee a DA or DR increase.
Are there free tools to check DA and DR?
Check the providers' own public checkers and current free-access options. Query allowances can change; use the same provider and date when comparing sites instead of mixing scores from unrelated tools.
