Understanding Domain Authority (DA) is crucial if you want your website to rank on Google. In this in-depth guide, we’ll explain what DA means, how it works, and how you can improve it to boost your SEO results.
What is Domain Authority in SEO?
Domain Authority (DA) is a ranking metric developed by Moz that predicts how likely a website is to rank on search engine result pages (SERPs). It’s scored on a scale from 1 to 100—higher scores mean a greater ability to rank.
While DA is not a Google ranking factor, it correlates strongly with SEO success and competitiveness.
How is Domain Authority Calculated?
Moz uses machine learning algorithms to calculate DA based on:
Number and quality of backlinks
Linking root domains
Site structure and usability
Spam score
Overall domain trust
DA is relative, meaning it's more useful for comparing one domain to another—not as an absolute SEO score.
Why is Domain Authority Important in SEO?
Although Google doesn’t officially use DA in its algorithm, here's why it matters:
✅ Benchmark your site’s authority against competitors
✅ Track your SEO progress over time
✅ Identify high-DA sites for backlink opportunities
✅ Build trust with advertisers, clients, and partners
A high DA often indicates a strong backlink profile and good overall site health.
What is a Good Domain Authority Score?
There’s no “perfect” DA, but here's a general breakdown:
1–20: New or low-authority websites
21–40: Developing websites with some SEO efforts
41–60: Established sites with good link profiles
61–80: Highly competitive, trusted domains
81–100: Authority giants like Google, Wikipedia, Amazon
Pro Tip: Focus on improving your DA rather than comparing it to mega-sites.

Building authority takes time and consistency—but the long-term benefits are massive.
Domain Authority vs Page Authority: What’s the Difference?
While Domain Authority (DA) measures the ranking potential of an entire domain,
Page Authority (PA) predicts the ability of a single page to rank.
Use DA to compare overall websites
Use PA to assess and improve individual blog posts or landing pages
Both metrics are helpful when planning SEO strategies or outreach campaigns.
Is Domain Authority a Google Ranking Factor?
No, Google does not use Moz's Domain Authority in its algorithm. However:
A higher DA usually reflects a stronger link profile
Strong backlinks are a confirmed Google ranking factor
So while DA is a third-party metric, it often aligns with SEO performance.
Final Thoughts: Should You Focus on Domain Authority?
Yes—but with balance.
Don’t obsess over the number. Instead:
Focus on building quality content
Earn authoritative backlinks
Ensure your site delivers a great user experience
DA will grow naturally over time if your overall SEO game is strong.
Conclusion: Mastering Domain Authority for SEO Success

Domain Authority is a reliable indicator of SEO strength
