Domain Authority (DA) is a metric created by Moz to estimate how well a website might perform in search engine result pages (SERPs). The DA score ranges from 1 to 100, with higher numbers indicating a stronger likelihood of ranking higher in search results.

This score is determined using Moz’s extensive Link Explorer web index, which incorporates multiple factors into its calculation. At its core, Domain Authority employs a machine learning model to identify the “best fit” algorithm. This algorithm aligns Moz’s link data with real-world search rankings, ensuring the DA metric remains relevant and predictive.

The process involves assessing a domain’s backlink profile and how frequently it shows up in search results. It’s important to note that DA is a comparative metric, designed to help evaluate the ranking strength of a domain relative to others, rather than a direct ranking factor used by search engines.

With its comprehensive approach, Domain Authority provides valuable insights for understanding website performance in the competitive landscape of search engine rankings.

How Domain Authority is Determined?

Domain Authority (DA) is calculated by considering multiple factors such as the number of linking root domains and the overall quantity of links pointing to a website, resulting in a single DA score. This score is generated by a machine learning algorithm that predicts how often a domain is likely to appear in Google’s search results compared to its competitors. Domains with more unique referring domains tend to achieve better DA scores, signifying a stronger backlink profile and higher potential for search engine ranking. This score serves as a useful comparison tool to gauge the “ranking strength” of a website over time. However, it’s important to note that Domain Authority is not a Google ranking factor and doesn’t directly impact your position in search results.

Following the Domain Authority 2.0 update in early 2019, the DA score calculation relies on machine learning predictions about how often a domain is used in Google’s search results. For example, if Domain A is more likely to appear in search results than Domain B, Domain A’s DA will typically be higher. To dive deeper into the DA 2.0 update, you can explore this presentation or review this comprehensive whitepaper on how to leverage DA metrics.

Since DA relies on machine learning, a domain’s score can fluctuate based on new or changing data points. For instance, if Facebook were to gain billions of new links, the DA of other sites would decrease in comparison. As highly authoritative domains like Facebook build bigger link profiles, they dominate the higher DA slots, leaving less room for other sites. Therefore, it’s easier to increase your DA from 20 to 30 than from 70 to 80. Consequently, it’s best to view Domain Authority as a relative metric rather than an absolute one.

What Constitutes a Good or Average Domain Authority Score

A common question in the SEO world is, “What’s a good or average Domain Authority (DA) score?” The truth is, there’s no definitive answer. Your DA score depends on a variety of factors, such as your resources, the competition, and your specific SEO objectives. For instance, is a DA of 30 good? It could be, but it depends on your unique situation.

Every website starts with a DA score of one, and this score increases as the site builds authoritative backlinks. Websites with more high-quality external links typically have a higher DA, while smaller businesses with fewer links may have lower scores. To get a better idea of the impact of DA, check out Moz’s list of the top 500 sites and see how the most successful sites use DA to improve their rankings.

Because Domain Authority is a predictor of a site’s ranking potential in a given competitive environment, you shouldn’t set your DA target in isolation. Look at the DA scores of your direct competitors in the search engine results pages (SERPs). Your goal should be to surpass their DA scores. Since DA is a relative metric, there’s no universally “good” or “bad” DA. Instead, what matters is how your DA compares to others within your niche.

What Are the Best Ways to Increase Your Domain Authority?

To boost your Domain Authority (DA), focus on improving your site’s overall SEO health, with a special emphasis on acquiring high-quality external links.

Domain Authority is influenced by numerous factors, so it may seem challenging to directly control. This metric is designed to predict how competitive a website will be in Google’s search results, considering that Google’s ranking system evaluates many different factors. Therefore, any metric attempting to predict Google’s rankings must reflect this complexity and include a wide range of elements.

The Importance of Linking Root Domains for Domain Authority

Linking root domains is essential when it comes to determining a website’s Domain Authority (DA) score. A linking root domain is a unique domain that directs a link to a website, and the total number of these domains plays a key role in calculating DA. In simple terms, it reflects the variety and quality of a website’s backlink profile.

When a website has a higher number of linking root domains, its DA score tends to rise, showing that the website is well-recognized and trustworthy within its field. On the other hand, a website with fewer linking root domains may see a drop in its DA score, potentially signaling a lack of credibility.

To boost the number of linking root domains, website owners should focus on creating valuable, high-quality content that naturally attracts backlinks from other reputable sites. Implementing link-building strategies such as guest blogging, broken link building, and reaching out to resource pages can also drive more links. By diversifying and improving your backlink profile, you can elevate your DA and enhance your website’s overall SEO performance.

Debunking Common Myths About Domain Authority

There are many myths surrounding Domain Authority (DA) that can cause confusion and lead to misunderstandings. Here are a few key ones to keep in mind:

  1. DA is a direct ranking factor: One of the most widespread misconceptions is that DA is a direct ranking factor used by Google to determine a website’s position in search results. However, DA is actually a metric developed by Moz, designed to predict a site’s ranking potential rather than being a factor directly used by Google.
  2. DA is the only metric that matters: While DA is an important metric, it’s far from the only one that matters. Metrics such as Page Authority, Domain Rating, and keyword rankings all provide critical insights into your site’s SEO health. Relying solely on DA can offer a misleading view of your site’s performance.
  3. DA is a fixed score: Some people believe that DA is a fixed score, but in reality, it is dynamic and changes over time. Your DA can fluctuate based on factors like the quality and number of backlinks, as well as content updates.
  4. DA is the same as PageRank: While both DA and PageRank measure a website’s authority, they are not the same. Each uses different algorithms and data sources, and understanding these distinctions is essential to interpreting your site’s SEO performance accurately.

By clearing up these misconceptions, you can more effectively leverage Domain Authority in your SEO strategy and avoid common pitfalls.

  3. Optimize Website Structure and Design: Make sure your website is fast, mobile-friendly, and user-friendly. A clear navigation structure, alongside optimized images and videos, can improve user experience and positively impact search engine rankings.
  4. Focus on Building Quality Backlinks: Obtain high-quality backlinks from authoritative sites. Techniques like guest blogging, broken link building, and resource page link building are effective strategies to strengthen your backlink profile and boost your Domain Authority.

By consistently implementing these best practices, you can significantly improve your website’s Domain Authority and visibility in search results.

How to Use Domain Authority Effectively in Your SEO Strategy

Domain Authority (DA) plays a critical role in shaping your SEO strategy, offering insights into your website’s potential ranking and competitiveness. Here’s how you can effectively use DA to enhance your SEO efforts:

  • Track Changes to Your DA Score: Keep a close eye on fluctuations in your DA score to identify trends. A growing DA score signifies improvements in SEO, while a declining score highlights areas that require attention.
  • Compare DA Scores with Competitors: Compare your DA with that of your competitors to gauge your performance. A higher DA score indicates an edge, while a lower score reveals opportunities to improve your website’s SEO.
  • Focus on Quality Link Building: Use DA to focus your link-building strategy. Prioritize obtaining backlinks from high-authority websites, as they can boost your DA and overall SEO performance.
  • Assess Content Quality: DA can also help you evaluate your content’s quality. Ensure it aligns with both user intent and search engine standards, as quality content attracts backlinks, positively influencing your DA.

By integrating DA into your SEO strategy, you gain valuable insights into your website’s competitive standing and can make data-driven decisions to boost SEO performance. This approach ensures more targeted efforts and better rankings.

How to Avoid the Common SEO Mistakes

Improving your website’s Domain Authority (DA) is essential for enhancing your online visibility, but several common mistakes can hinder your progress. Here’s how to avoid the most frequent errors:

  1. Avoid Buying Backlinks: Purchasing backlinks may seem like a quick way to improve your DA, but it can actually harm your website’s credibility. Instead, focus on acquiring backlinks through valuable, high-quality content that naturally attracts links over time.
  2. Don’t Over-Optimize: Over-optimizing your content, including excessive keyword stuffing and meta tag manipulation, can result in penalties from search engines. Aim for a balanced, user-centered approach where the focus is on relevance and providing value to your audience.
  3. Neglecting Technical SEO Is a Mistake: Technical SEO plays a crucial role in improving DA. Ensure that your website is fast, mobile-responsive, and secure. Regularly audit and fix any technical issues that might affect the overall performance of your website.
  4. Quality Content Is Key: High-quality content is non-negotiable when it comes to boosting DA. Ensure that your content is well-researched, relevant, and engaging. Avoid publishing content that provides little to no value to your target audience.
  5. Track Your Progress: Use tools like Moz to keep track of your DA and monitor improvements over time. Regular tracking helps identify areas that need adjustment and allows you to fine-tune your SEO strategy for maximum results.

By following these guidelines and avoiding these common pitfalls, you’ll be on the path to improving your website’s Domain Authority and boosting your online presence.

Why Did My Domain Authority Score Change?

Domain Authority (DA) is a dynamic metric, influenced by several factors, which makes it challenging to pinpoint the exact cause of a change in your score. If you’ve noticed fluctuations, whether positive or negative, here are some common reasons:

  • Your link profile growth may not have been fully captured by the web index yet.
  • Top-authority sites might have seen significant link growth, affecting the scaling process.
  • You may have earned links from sources that don’t contribute to Google rankings.
  • We could have crawled (and indexed) a different set of linking domains than in previous crawls.
  • Your DA may be more sensitive to fluctuations if it’s on the lower end of the scale.
  • The implementation of Domain Authority 2.0 in 2019 caused an average decrease of 6% in DA across all websites due to restructuring and recalibration.

Why Comparisons Matter More Than Absolutes

It’s essential to understand that Domain Authority is a comparative metric. This means that your score is relative to the entire domain ecosystem. So, even if you improve your SEO efforts and link profile, your DA may not always reflect these improvements. Think of it like rankings on a “best of” list — even if you improve, the ranking could change based on how other sites or countries perform.

For instance, if Singapore improved its air quality in 2021, it might not stay at #1 if other countries, like Denmark or New Zealand, also improved or joined the rankings. In this case, the scale itself is adjusting, which could cause Singapore’s rank to drop even though its air quality improved.

Domain Authority works in a similar way. It’s based on machine learning and continuous comparisons with other websites. After each recalculation, your score might decrease even if your link profile has improved. This is because it’s a relative metric, and scores are affected by the performance of other domains, not just your own improvements.

In conclusion, understanding DA fluctuations requires a shift in perspective: it’s about comparison, not absolutes.

Different Types of Authority Scores in SEO

Page Authority, Domain Authority, and Brand Authority™ are key metrics in SEO that determine how well your website can rank on search engines. Each authority score gives you insight into various aspects of your website’s performance and online influence. Page Authority measures the potential ranking strength of a single page, Domain Authority evaluates the overall power of your entire website, and Brand Authority™ tracks how well your brand is recognized and trusted. Together, these scores provide a comprehensive view of your site’s SEO potential and ability to reach your audience.

Page Authority vs. Domain Authority

Domain Authority (DA) and Page Authority (PA) are two important metrics in SEO, but they measure different aspects of a website’s performance. Domain Authority assesses the overall ranking potential of an entire domain or subdomain, predicting how well it might rank on search engine results pages. On the other hand, Page Authority focuses on the individual strength of specific pages within that domain, offering insights into how well a particular page may perform.

Both metrics are critical for understanding your website’s SEO potential, but they measure ranking power on different levels—DA looks at the big picture, while PA hones in on specific pages. By improving both, you can significantly boost your overall SEO performance.

Conclusion

Domain Authority (DA) is a powerful metric for assessing a website’s potential to rank in search engine results. While it’s not a direct ranking factor for Google, it offers valuable insights into a site’s SEO performance and competitive standing. By focusing on acquiring high-quality backlinks, producing engaging content, and monitoring your DA score regularly, you can enhance your website’s overall authority and visibility. Keep in mind that DA is a comparative metric, so the key to success lies in improving your score relative to your competitors. Integrating DA into your SEO strategy can help you make informed decisions and optimize your website for better search engine rankings.

Domain Authority (DA) gauges both the quality and quantity of backlinks, which continue to be one of the most significant (arguably the top) factors in Google’s evaluation of a website’s authority. While DA isn’t the ultimate measure of anything, it provides a handy shorthand for assessing a site’s link-based authority. I’ve found it especially useful in two areas: A) evaluating how difficult it will be to rank for a specific search engine results page (SERP), and B) assessing the value of a backlink from a particular website.

Domain Authority (DA) is often considered to correlate with a page’s ability to rank, but in my experience, the connection between high DA and high rank is only moderate—DA is not a “critical” ranking factor. Additionally, it’s important to note that Domain Authority can be easily manipulated.

As a media and news site, you have a prime opportunity to build genuine authority and rankings through ethical practices. Focus on creating in-depth, authoritative content that attracts attention from respected websites and influencers in your chosen niches. Engage with these influencers, share your articles, and request backlinks to your content. For further insights on this strategy, check out Brian Dean’s website, Backlinko.

It’s interesting that Google representatives, like John Mueller, have recently discussed the role of certain sitewide elements in the ranking process. However, these elements are not a “score” that you can quantify with something like domain authority. Instead, they are broad assessments of the site’s overall quality and trustworthiness. Notice, I didn’t say “authority.” These factors act more as tie-breakers, tipping the scale in one direction when other ranking signals are equal for a page.

John Mueller recently shared an example explaining why plagiarized content might rank higher, even if Google “knows” it’s not original. The reason is that Google perceives the site hosting the copied content as more trustworthy and of higher quality overall.
