What is a Good Domain Authority? Complete Guide to DA Scores

Understanding Domain Authority

Domain Authority (DA) is a metric developed by Moz in 2004 that predicts how likely a website is to rank on Google search engine results pages. The score ranges from 0 to 100, with higher scores indicating greater ranking potential. However, it’s crucial to understand that Domain Authority is not a direct Google ranking factor—Google does not use it in its algorithm. Instead, DA serves as a third-party metric that gives webmasters and SEO professionals an indication of their site’s potential performance in search results based on comparative analysis with competitors.

Moz calculates Domain Authority using machine learning algorithms that analyze multiple signals, including the quality and quantity of backlinks pointing to your site, your link profile diversity, spam score, and even your current Google rankings. The algorithm considers more than 40 different signals to determine your DA score. This comprehensive approach makes DA a useful benchmark for understanding your website’s competitive position, even though it’s not directly used by search engines themselves.

The Comparative Nature of Domain Authority

The most important concept to grasp about Domain Authority is that it is fundamentally a comparative metric, not an absolute measure of quality. This means there is no universally “good” DA score—what matters is how your score compares to your direct competitors in your industry. A Domain Authority of 20 might be excellent if all your competitors have scores between 15-25, but it would be poor if your competitors are ranking with scores in the 40s or 50s.

Think of Domain Authority like a competitive ranking system within your industry. If you’re in a niche market with lower overall authority sites, a DA of 30 could position you as a leader. Conversely, if you’re competing in a highly competitive industry where established players have DA scores of 60+, you would need to work toward reaching at least 50-60 to be competitive. This relative nature is why Moz specifically recommends treating DA as a comparative tool rather than an objective target.

How Domain Authority Impacts Your SEO Strategy

Domain Authority serves several critical functions in your SEO strategy beyond just being a number to track. First, it helps you assess the difficulty of ranking for specific keywords. Websites with higher Domain Authority typically rank for more competitive keywords with higher search volume, while sites with lower DA tend to rank for less competitive, long-tail keywords. Understanding your DA relative to competitors helps you identify which keywords are realistically achievable for your site.

Second, DA helps you evaluate the value of backlinks you receive. A backlink from a high-authority site (DA 60+) passes significantly more link value and credibility than a backlink from a low-authority site (DA 10-20). This is why quality matters more than quantity when building your backlink profile. When evaluating link-building opportunities, you should prioritize getting backlinks from sites with higher Domain Authority than your own, as these will have the greatest impact on improving your rankings.

Third, Domain Authority serves as an excellent metric for measuring the success of your link-building campaigns over time. As you earn more high-quality backlinks, your DA should gradually increase. If you notice your DA is stagnant or declining while competitors are improving, it signals that your link-building strategy may need adjustment. Tracking your DA alongside your competitors’ scores gives you clear visibility into whether your SEO efforts are moving you ahead or falling behind in your market.

The Logarithmic Scoring System

One critical aspect of Domain Authority that many people misunderstand is that it operates on a logarithmic scale, not a linear one. This means the effort required to increase your DA becomes exponentially harder as your score increases. For example, you might need just one or two high-quality backlinks to move from DA 5 to DA 10, but you could need dozens of high-quality backlinks to move from DA 50 to DA 60.

This logarithmic nature has important implications for your SEO strategy. It means that when you’re starting out with a low DA, you can see relatively quick improvements by focusing on acquiring quality backlinks and creating valuable content. However, as your authority grows, the improvements will slow down. This is why many SEO professionals recommend focusing on relative growth compared to competitors rather than trying to reach arbitrary DA milestones. If you’re consistently improving your DA faster than your competitors, you’re winning in your market, even if your absolute score is lower.

Key Factors That Influence Your Domain Authority

Your Domain Authority is influenced by several interconnected factors that Moz analyzes when calculating your score. The most significant factor is your link profile—the quality, quantity, and diversity of backlinks pointing to your site. Sites with many high-quality inbound links from authoritative, relevant domains typically have higher DA scores. However, Moz also considers the diversity of your backlink sources. A natural link profile includes links from various types of websites (blogs, news sites, industry resources, directories) rather than concentrated links from just a few sources.

Beyond backlinks, Moz factors in your Moz Spam Score, which evaluates whether your site exhibits characteristics of low-quality or spammy websites. Sites engaging in link schemes, buying links, or using private blog networks typically experience drops in their Domain Authority. Your current Google rankings also influence your DA score, as Moz incorporates real-world search performance data into its calculations. Additionally, Moz considers your site structure and content quality. Well-organized sites with coherent information architecture and high-quality, relevant content tend to have higher DA scores.

It’s important to note that Domain Authority is a relative metric that shifts as the entire web ecosystem changes. When major sites like Facebook, Google, or Wikipedia acquire significant new backlinks, it can affect the DA of every other site in the system because DA is calculated relative to all other sites. This means you might see fluctuations in your DA score even if you haven’t made any changes to your site, simply because the competitive landscape has shifted.

Strategies to Improve Your Domain Authority

Improving your Domain Authority requires a multi-faceted approach focused on building a strong, natural backlink profile and creating valuable content. The most effective strategy is to focus on acquiring high-quality backlinks from authoritative, relevant websites. This means reaching out to industry publications, complementary businesses, and thought leaders in your space to earn links through guest posting, partnerships, or by creating content so valuable that others naturally want to link to it.

Creating exceptional, original content is fundamental to earning backlinks naturally. Content that provides unique insights, original research, comprehensive guides, or data-driven analysis is more likely to be referenced and linked to by other websites. When you create content that genuinely solves problems or answers questions better than existing resources, other site owners have a reason to link to you. This approach is far more sustainable than trying to artificially inflate your DA through questionable tactics.

Optimizing your on-page SEO also contributes to your Domain Authority over time. Ensure your site has proper technical SEO implementation, including fast loading times, mobile responsiveness, clean URL structures, and proper use of meta tags and headers. A well-structured site with good user experience signals quality to search engines and makes your content more likely to be shared and linked to. Additionally, diversifying your backlink profile by earning links from different types of sources—industry blogs, news sites, resource pages, social media, and directories—creates a more natural and robust link profile that search engines view more favorably.
