Check the Domain Authority: Why It Matters and How to Use It for SEO Growth
In the competitive world of digital marketing, understanding how well your website performs in comparison to others is essential. One of the most effective ways to evaluate your site’s credibility and ranking potential is to check the domain authority. Whether you’re a blogger, entrepreneur, SEO specialist, or business owner, knowing where your website stands gives you a significant advantage in planning your digital strategy.
Domain authority (DA) has become a benchmark metric for estimating a website's strength in search engine rankings. It doesn't just tell you how your site is doing, but also helps you assess competitors, spot growth opportunities, and refine your marketing tactics.
In this article, we’ll explore what domain authority is, how it’s calculated, why it matters for SEO, and how you can use this knowledge to improve your website’s performance over time.
What Is Domain Authority?
Domain Authority, often abbreviated as DA, is a score developed by Moz that predicts how likely a website is to rank on search engine result pages (SERPs). The score ranges from 1 to 100, with higher numbers indicating a greater ability to rank.
It's important to note that DA is not a direct ranking factor used by Google, but it is widely respected and used within the SEO community as a reliable indicator of website performance.
How Is Domain Authority Calculated?
DA is calculated based on several core factors, primarily focused on a website’s backlink profile. These include:
-
Quantity and Quality of Backlinks: Not all backlinks are equal. Links from high-authority and relevant sites are more valuable than a large number of low-quality links.
-
Referring Domains: The number of unique domains that link to your site is often more impactful than the total number of links.
-
Spam Score: Websites with a high spam score are considered less trustworthy and can negatively impact DA.
-
Link Diversity: A good mix of do-follow and no-follow links from various domains helps build a natural profile.
The algorithm uses a logarithmic scale, meaning it’s easier to grow your score from 10 to 20 than from 70 to 80. As your score increases, gains become more challenging but more rewarding.
Why You Should Check the Domain Authority
There are several key reasons why regularly checking your domain authority is a smart move:
1. Measure SEO Progress
DA gives you a quick overview of how your site is evolving in the eyes of search engines. If your score is consistently increasing, it’s a strong sign that your SEO efforts are working.
2. Evaluate Competitors
You can’t succeed without knowing the competition. By checking your competitors’ domain authority, you can see where they’re gaining ground and what strategies might be worth emulating.
3. Refine Link-Building Strategies
Knowing your DA helps you understand which backlink opportunities will provide the most value. Aim for links from domains with higher authority than your own to grow faster.
4. Improve Content Strategy
Pages with high authority often perform well due to quality content and strong backlinking. Analyze what content is performing best and replicate that success in future posts.
How to Check the Domain Authority
Most SEO tools provide an option to check domain authority by simply entering the website’s URL. These tools return not only the DA score but also other useful metrics such as:
-
Number of backlinks
-
Referring domains
-
Page authority (PA)
-
Spam score
-
Link profile health
Advanced tools may allow for bulk checking, keyword tracking, and historical performance data.
What Is a Good Domain Authority Score?
There’s no universal benchmark for what makes a “good” DA score because it’s relative to your niche and competition. However, here’s a rough breakdown:
-
1–20: New or underdeveloped websites.
-
21–40: Growing websites building traction.
-
41–60: Established websites with some authority.
-
61–80: Strong domains with competitive presence.
-
81–100: Elite, highly trusted websites (e.g., Wikipedia, Google).
Instead of aiming for a perfect score, focus on outperforming direct competitors and improving steadily over time.
Tips to Improve Domain Authority
While checking DA is valuable, the real benefit comes from using that information to grow. Here are some tried-and-true methods to raise your score:
1. Create High-Quality Content
Great content naturally earns backlinks. Focus on value-packed, original articles, guides, infographics, and videos that others want to reference.
2. Earn Authoritative Backlinks
Use guest blogging, digital PR, broken link building, and influencer outreach to secure links from reputable domains.
3. Clean Up Toxic Links
Regularly audit your backlink profile and disavow links from spammy or irrelevant sources. This helps reduce your spam score and keeps your DA healthy.
4. Improve Internal Linking
Connect related content on your website. Internal linking helps distribute authority evenly and improves crawlability.
5. Optimize Site Speed and Mobile Experience
Search engines favor sites that load quickly and perform well on all devices. Optimize images, minimize code, and ensure your site is mobile-friendly.
Common Misconceptions About Domain Authority
Let’s clear up a few myths:
-
“DA is a Google ranking factor.” It’s not. It’s a third-party metric that correlates with ranking potential but isn’t used by Google itself.
-
“You need a high DA to rank.” A low DA doesn’t mean you can’t rank. Niche websites with low scores can still perform well for specific, low-competition keywords.
-
“Only backlinks matter.” While important, DA is influenced by multiple factors including content quality, site health, and spam score.
How Often Should You Check It?
Checking once a month is a good rule of thumb. It gives you time to see meaningful changes while also keeping tabs on progress. If you’re actively running SEO campaigns or link-building initiatives, you might choose to check it biweekly.
Conclusion
To grow online successfully, you need to check domain and page authority regularly to evaluate where your website stands and how to improve it. These insights allow you to make smarter decisions about your SEO strategy, content development, and link-building efforts.
