Check the Domain Authority: Why It Matters for Your SEO Strategy
If you're running a website in today’s digital landscape, you’ve probably come across the term Domain Authority (DA). Developed by Moz, Domain Authority is a metric that predicts how well a website will rank on search engine result pages (SERPs). Whether you're a small business owner, digital marketer, blogger, or SEO enthusiast, understanding and knowing how to check the domain authority of your website is crucial.
In this comprehensive guide, we’ll break down what Domain Authority means, how it’s calculated, why it matters, and how to interpret your results. Most importantly, we’ll share tips on how you can improve your DA score over time.
What is Domain Authority?
Domain Authority is a search engine ranking score developed by Moz. It ranges from 1 to 100, with higher scores indicating a better ability to rank. Think of it as a comparative metric — it’s not absolute. For instance, a DA of 30 could be great in a niche with low competition, while a DA of 60 might be average in a highly competitive industry.
Unlike Google’s official ranking system, Domain Authority is not a direct ranking factor. However, it is widely used in the SEO industry to assess the strength of a website’s backlink profile and its overall online authority.
Why Should You Check the Domain Authority?
Knowing your website’s DA helps you understand how search engines might perceive the credibility and trustworthiness of your site. Here’s why it matters:
1. Measure SEO Progress
As you invest in SEO, content marketing, and link-building efforts, your DA score can help you measure the effectiveness of these strategies.
2. Competitor Benchmarking
By checking the DA of your competitors, you can evaluate how your site stacks up and identify areas for improvement.
3. Evaluate Guest Posting Opportunities
When reaching out for backlinks or guest post collaborations, a website’s DA helps determine if the opportunity is valuable.
4. Build Authority and Trust
Advertisers, collaborators, and potential clients often use DA as an indicator of a website’s reliability and quality.
How is Domain Authority Calculated?
Domain Authority is based on a machine learning algorithm that evaluates a wide range of factors, including:
-
Number of total links (inbound and outbound)
-
Quality of linking root domains
-
MozRank and MozTrust
-
Spam score
-
Website age and consistency
It’s important to remember that DA is logarithmic. That means increasing your DA from 20 to 30 is much easier than going from 70 to 80. Progress gets harder as your score climbs.
What is a Good Domain Authority Score?
There’s no “ideal” DA score that applies to everyone. Here’s a rough breakdown:
-
1–20: New or low-authority sites
-
21–40: Growing websites with basic backlink profiles
-
41–60: Strong, competitive sites
-
61–80: High-authority domains
-
81–100: Major websites like Google, Wikipedia, Amazon, etc.
Use your competitors as a benchmark to determine what’s considered good in your specific niche.

Tips to Improve Your Domain Authority
Improving your DA doesn’t happen overnight. It requires a solid SEO strategy, persistence, and content quality. Here’s how to do it:
1. Get High-Quality Backlinks
Backlinks from authoritative, relevant sites are the most effective way to boost your DA. Focus on quality over quantity.
2. Create Valuable Content
Publishing helpful, in-depth content earns backlinks organically. Invest in blog posts, how-to guides, case studies, and original research.
3. Internal Linking Strategy
Proper internal links distribute page authority across your site and make it easier for search engines to crawl and index your pages.
4. Fix Broken Links
Broken outbound or internal links can hurt user experience and SEO. Use tools like Screaming Frog or Ahrefs to identify and fix them.
5. Speed and Mobile Optimization
Fast-loading, mobile-friendly websites rank better and reduce bounce rates — both of which influence DA indirectly.
6. Avoid Black Hat Tactics
Never buy backlinks or engage in spammy link exchanges. These might give you a short-term boost but can lead to penalties and long-term damage.
Common Misconceptions About Domain Authority
- DA is a Google Ranking Factor
No, Google doesn’t use Moz’s DA. However, the factors that improve your DA (like quality backlinks) do influence your actual Google rankings.
- Higher DA Guarantees Higher Rankings
Not necessarily. DA is just one of many signals. Content relevance, user experience, and on-page optimization also play significant roles.
- All DA Checkers Are the Same
Different tools use different databases and algorithms. Always use more than one tool for a broader picture.
Conclusion
When you’re trying to improve your website’s SEO, it’s essential to check domain and page authority regularly. These scores give you insights into your site’s health and potential, help you track your SEO growth, and let you gauge how competitive you are in your niche.
