What is Domain Authority (DA) and Why Is It Important?
Domain Authority (DA) is a search engine ranking score developed by Moz, a popular SEO tool. It predicts how likely a website is to rank on search engine results pages (SERPs). DA is measured on a scale from 1 to 100 — higher the score, the greater the ranking power.
✅ How DA Is Calculated?
DA is based on multiple factors, mainly:
-
Quality and quantity of backlinks
-
Linking root domains (how many different websites link to yours)
-
Spam score
-
Site structure and SEO performance
Note: Like DR (Domain Rating by Ahrefs), DA is also a third-party metric — Google does not use it directly, but it’s useful for SEO planning.
📊 DA Score Meaning (With Levels)
| DA Range | Level | Meaning |
|---|---|---|
| 1 – 10 | Very Low | New or small site; almost no authority. |
| 11 – 30 | Low | Some links, basic presence, but still low trust. |
| 31 – 50 | Medium | Moderate authority; can rank well with strong content. |
| 51 – 70 | High | Strong backlink profile; trusted by search engines. |
| 71 – 90 | Very High | Top websites in their industry or niche. |
| 91 – 100 | Elite | Major global websites (e.g., YouTube, Wikipedia, Facebook). |
🔍 Why Is DA Important?
-
SEO Benchmarking
You can compare your DA with your competitors to understand your SEO strength. -
Backlink Strategy
Websites with high DA are more valuable for link building. Getting a backlink from a DA 80 site gives much more SEO value than from a DA 20 site. -
Client Reporting / Growth Tracking
Agencies and website owners often use DA as a quick metric to measure progress and authority over time. -
Content Strategy
A high-DA website usually means your content is performing well and being linked to by others.
⚠️ Important Notes:
-
DA can fluctuate when Moz updates its algorithm or when your backlinks change.
-
DA is relative — what’s considered good in one niche may not be good in another.
-
A high DA alone doesn’t guarantee top rankings — content quality, user experience, and on-page SEO also
| DA Score | Level | Meaning |
|---|---|---|
| 0 – 10 | Very Low | Naya website ya backlinks nahin hain. Google pe rank karna mushkil. |
| 11 – 20 | Low | Thode bahut backlinks hain. Initial SEO work kiya gaya hai. |
| 21 – 30 | Below Average | Basic authority develop hui hai, lekin abhi growth ki zarurat hai. |
| 31 – 40 | Moderate | Decent backlinks; site rank kar sakta hai agar content strong ho. |
| 41 – 50 | Good | Achha authority level. Consistent backlinks aur SEO ka result. |
| 51 – 60 | Strong | High authority website. Search engines trust karte hain, ranking possible. |
