Check the Domain Authority: Why It Matters and How to Do It Right

In the vast landscape of digital marketing and SEO, staying ahead of the competition requires more than just publishing great content. One crucial factor that plays a pivotal role in how search engines view and rank your website is your domain authority (DA). Whether you're a seasoned digital marketer, a blogger, or a business owner building an online presence, it’s essential to understand how and why you should check the domain authority of your website—and of others.

But what exactly is domain authority? How is it calculated? Why does it matter? And most importantly, how can you improve it over time? This in-depth guide covers it all.


What Is Domain Authority?

Domain Authority is a search engine ranking score developed by SEO software companies like Moz to predict how well a website will rank on search engine result pages (SERPs). The score ranges from 1 to 100, with higher scores indicating a greater likelihood of ranking higher.

It's important to note that domain authority is not a Google metric. It’s a third-party calculation based on several factors, including:

  • The number and quality of backlinks

  • The linking root domains

  • Site structure and SEO performance

  • Content relevance and consistency

A newly launched website will have a lower DA score, while a site like Wikipedia or Forbes has a very high DA due to years of authoritative content and countless backlinks from credible sources.


Why You Should Check the Domain Authority

Checking domain authority isn't just for SEO geeks. It’s an essential practice for anyone who wants their website to gain visibility, trust, and traffic. Here’s why you should pay attention to it:

1. Evaluate Your Website’s Health

DA gives you a quick overview of how strong your website is in the eyes of search engines. It helps you assess the results of your SEO efforts and provides a benchmark for growth.

2. Competitive Analysis

When you're trying to rank for a specific keyword, knowing the DA of your competitors can help you gauge the level of difficulty. If your DA is much lower than the competition, you may need to strengthen your backlink profile or focus on long-tail keywords.

3. Assess Link Building Opportunities

If you're engaging in outreach or guest posting, it's wise to check the domain authority of the sites you’re targeting. You want backlinks from high-authority sites for better SEO value.

4. Prevent Association with Spammy Sites

Low DA can sometimes indicate a spammy or poorly maintained website. Avoiding backlinks from such sites protects your reputation.


What Is a Good Domain Authority Score?

There’s no universal “good” score, as what’s considered good varies depending on your industry and competitors. However, here’s a general guideline:

  • 1–20: New websites or those with minimal SEO work.

  • 21–40: Decent domain authority—many growing businesses fall in this range.

  • 41–60: Competitive; solid backlink profile and good SEO foundation.

  • 61–80: Strong authority and trust across the web.

  • 81–100: The digital elite—sites like Google, YouTube, and news outlets.

Focus more on improving your score over time and staying ahead of similar sites in your niche rather than chasing a perfect 100.


How to Check the Domain Authority

To check the domain authority, you’ll need a reliable SEO tool. Many free and paid platforms can provide this metric, often alongside other helpful insights like Page Authority (PA), backlinks, and referring domains.

Here’s what you’ll typically see:

  • Domain Authority (DA): Your site's overall strength

  • Page Authority (PA): The authority of a specific page or blog post

  • Backlink Profile: Number of total links and linking domains

  • Spam Score: A warning signal if the site might be penalized by search engines

While it's helpful to use multiple tools to cross-verify results, most tools offer a similar range of information that helps you plan your SEO efforts.


What Is Page Authority (PA) and How Is It Different?

While DA looks at the strength of the overall domain, Page Authority (PA) measures the strength of an individual webpage. For example, your homepage might have a PA of 60, while a newly published blog post might only have a PA of 15.

Improving PA is great for boosting individual pages in search results, especially if you’re targeting specific keywords or want a particular post to perform better.


Tips to Improve Your Domain Authority

Improving your DA isn’t about shortcuts—it’s about steady, strategic growth. Here’s what you can do to enhance your score over time:

1. Focus on High-Quality Backlinks

One strong link from an authoritative site is more valuable than dozens of low-quality links. Consider guest posting, digital PR, and influencer outreach.

2. Create Shareable, Link-Worthy Content

Infographics, in-depth guides, and case studies often attract organic links. The more your content is referenced by others, the stronger your domain becomes.

3. Fix Technical SEO Issues

Page speed, mobile responsiveness, clean URLs, and proper indexing play a role in how search engines evaluate your site. Tools like Google Search Console and Screaming Frog can help identify technical issues.

4. Remove or Disavow Toxic Backlinks

Low-quality or spammy backlinks can drag your score down. Regularly audit your link profile and disavow harmful links if needed.

5. Internal Linking Structure

Use strategic internal links to guide search engines and users across your site. This improves crawlability and strengthens individual page authority.

6. Keep Publishing

Consistency is key. Publishing high-quality content regularly signals to search engines that your site is active and growing.


Common Mistakes to Avoid

❌ Buying Backlinks

It might seem like a shortcut, but purchasing backlinks can backfire and result in penalties.

❌ Ignoring Mobile Optimization

With Google’s mobile-first indexing, a poor mobile experience can hurt your visibility and credibility.

❌ Focusing Solely on DA

DA is one of many indicators. A balanced SEO strategy considers content quality, user intent, on-page SEO, and technical performance.


Conclusion: Check Domain and Page Authority to Stay Competitive

To build a strong online presence, it’s essential to check domain and page authority regularly. These metrics offer insights into your website’s credibility, competitiveness, and SEO performance. By monitoring your authority scores, you can make informed decisions—whether you're analyzing competitors, choosing where to build backlinks, or tracking your SEO progress.
