What is Domain Authority (DA)?
Domain Authority (DA) is a proprietary metric developed by Moz that scores a website's overall strength and ranking potential on a scale from 1 to 100. The score is calculated using a machine learning algorithm that considers dozens of factors — primarily the quality and quantity of backlinks pointing to the domain.
Important to understand: DA is NOT a Google ranking factor. Google does not use Moz's DA score in its algorithm. However, DA is a useful proxy metric — sites with higher DA tend to rank better because they typically have stronger backlink profiles, which Google does care about.
DA vs DR: Understanding the Difference
| Metric | Provider | What It Measures | Scale |
|---|---|---|---|
| DA (Domain Authority) | Moz | Overall domain link strength | 1–100 |
| DR (Domain Rating) | Ahrefs | Strength of backlink profile | 0–100 |
| AS (Authority Score) | SEMrush | Combined link and traffic authority | 0–100 |
All three measure similar things but use different methodologies. Ahrefs DR is generally considered the most accurate by SEO professionals. Always check multiple metrics rather than relying on one tool alone.
How Moz Calculates Domain Authority
Moz's DA algorithm considers:
- Linking Root Domains: Number of unique domains linking to your site (most important factor)
- Total Links: Overall count of backlinks
- Link Quality: Authority of the linking domains (links from high-DA sites carry more weight)
- Link Diversity: Mix of dofollow, nofollow, text links, image links
- Spam Score: Proportion of links from spammy or low-quality sites
- MozRank and MozTrust: Internal Moz metrics for link popularity and trust
DA is logarithmic — it's much easier to go from DA 10 to 20 than from DA 70 to 80. The higher your DA, the harder each incremental point becomes.
What is a Good Domain Authority Score?
| DA Range | Assessment | Typical Sites |
|---|---|---|
| 1–10 | New site — building phase | Brand new domains, 0–3 months old |
| 11–20 | Early development | Young sites with some initial links |
| 21–40 | Growing — decent authority | Established niche blogs, local businesses |
| 41–60 | Good — competitive in most niches | Well-established industry blogs, news sites |
| 61–80 | Strong — high authority | Major industry publications, large brands |
| 81–100 | Very high — elite sites | Wikipedia, BBC, Times of India, Economic Times |
For context, most successful Indian niche blogs and tools sites target DA 30–50 within 2–3 years. Competing with Economic Times (DA 80+) for broad keywords is unrealistic for most sites — focus instead on niche-specific keywords where your topical authority matters more than raw DA.
DA Benchmarks for Indian Websites
- Economic Times: DA ~80–85
- Moneycontrol: DA ~75–80
- Livemint: DA ~70–75
- Freefincal (personal finance blog): DA ~45–50
- Stable Investor (niche investing blog): DA ~35–40
- New niche finance/SEO tool site (0–1 year): DA ~5–20
10 Proven Strategies to Increase Domain Authority
1. Build High-Quality Backlinks (Highest Impact)
DA is primarily driven by backlinks. Focus on acquiring links from high-DA, relevant sites:
- Guest posting on niche-relevant sites (DA 40+)
- Creating data-driven content/tools that earn natural links
- Digital PR — getting cited in news articles
- Broken link building — replacing dead links with your content
2. Increase Linking Root Domains
100 links from 100 different domains is far more valuable than 1,000 links from 1 domain. DA is heavily influenced by the diversity of your referring domains, not just total link count. Aim to continuously grow your unique referring domain count.
3. Publish Consistently High-Quality Content
Content is the engine that earns links. Long-form, research-backed, visually rich content (guides, data studies, tools) earns links passively over time. Thin, generic content earns none. Quality always beats quantity.
4. Remove or Disavow Toxic Links
Spammy backlinks drag down your DA and Spam Score. Regularly audit your backlink profile using Moz Link Explorer or Google Search Console. Use Google's Disavow Tool to negate toxic links you cannot get removed manually.
5. Optimise Internal Linking
Internal links distribute "link equity" across your site. Pages with no internal links receive no authority flow from your backlink-rich pages. Create a strong internal link structure from your most-linked pages to your most important content pages.
6. Fix Broken Links (Internal and External)
Internal broken links waste link equity. External broken links (to other sites) create a poor user experience. Both hurt SEO signals that indirectly affect DA over time.
7. Be Patient — DA Growth Takes Time
DA updates when Moz recrawls your backlink profile (approximately monthly). Meaningful DA improvements typically require consistent effort over 6–18 months. Sites that try to shortcut this with paid links or link schemes risk penalties.
8. Focus on Topical Authority
Even with moderate DA, you can outrank high-DA sites by building deep topical authority in a specific niche. A DA 30 site that covers everything about Indian stock market technical analysis can outrank DA 60 general sites for specific trading indicator queries.
9. Get Listed in Quality Directories
High-quality, niche-relevant directories (AMFI for financial sites, SEBI-registered platform lists) provide legitimate links. Avoid generic, low-quality directories.
10. Social Signals and Brand Mentions
While social shares aren't direct ranking factors, they drive traffic that leads to natural link acquisition. High-visibility content gets shared → reaches people who link to it → backlinks grow → DA improves.

FAQs: Domain Authority
Is Domain Authority a Google ranking factor?
No. Domain Authority is a Moz metric, not a Google metric. Google has its own internal "PageRank" algorithm which is not publicly shared. However, sites with high DA tend to rank well because they have strong backlink profiles — which Google does use as a key ranking factor. Think of DA as a useful approximation, not a direct cause.
How long does it take to increase Domain Authority?
Meaningful DA growth typically takes 6–18 months of consistent link building and content creation. Small improvements (DA 5 → 15) can happen in 3–6 months. Significant jumps (DA 30 → 50) require 1–2 years of sustained effort. DA is logarithmic — harder to increase at higher levels.
Can DA decrease?
Yes — DA can decrease if: (1) you lose backlinks that previously pointed to your site, (2) the overall DA of sites linking to you decreases, (3) Moz updates its algorithm (algorithm updates can cause widespread DA changes industry-wide). Monitor your DA monthly but don't panic over small fluctuations.
