DA, DR and AS#
| Metric | Provider | Scale |
|---|---|---|
| Domain Authority (DA) | Moz | 1–100 |
| Domain Rating (DR) | Ahrefs | 0–100 |
| Authority Score (AS) | Semrush | 0–100 |
Each tool calculates its score differently, mostly from the quantity and quality of linking domains. Scores are logarithmic — moving from 20 to 30 is much easier than from 70 to 80.
Is it a Google ranking factor?#
No. Google has repeatedly said it doesn’t use these third-party metrics. They’re estimates designed to approximate link-based authority.
How to use it sensibly#
- Compare your site with competitors in the same niche.
- Roughly qualify link opportunities — alongside relevance and real traffic.
- Track long-term trends in your link-building efforts.
Don’t buy links because a site has high DA; relevance and genuine audience matter far more. Related: backlinks, topical authority.
