What is Domain Authority in SEO

Domain Authority (DA) is a metric used in search engine optimization (SEO) to assess the overall authority and credibility of a website. Developed by Moz, DA is measured on a scale from 1 to 100, with higher scores indicating a stronger online presence and greater potential to rank well in search engine results. It takes into account various factors, such as the quality and quantity of backlinks, website content, and other SEO-related elements. Webmasters and SEO professionals often use DA as a reference when evaluating the strength of a domain or planning their link-building strategies.

What is Domain Authority?

Domain Authority (DA) is a metric developed by MOZ, a company that specializes in search engine optimization (SEO) tools and services. DA is used to evaluate the authority and credibility of a website in the eyes of search engines, particularly Google. It is not an official metric used by search engines themselves, but rather a proprietary score created by Moz to help website owners and SEO professionals assess the potential ranking strength of a website’s domain.

Domain Authority is measured on a scale from 0 to 100, with higher scores indicating a stronger and more authoritative website. The metric is calculated based on various factors, including the quality and quantity of backlinks (links from other websites pointing to the target site), the overall link profile, the age and history of the domain, and other SEO-related factors. Websites with a higher number of high-quality backlinks from reputable sources tend to have higher Domain Authority scores.

What is a Good Domain Authority?

Domain Authority (DA) is a metric developed by Moz that is used to measure the authority and credibility of a website. It is scored on a scale from 1 to 100, with higher scores indicating a stronger and more authoritative website. It’s important to note that Domain Authority is a proprietary metric developed by Moz and is not an official metric used by search engines like Google. It is often used as a reference point in the field of search engine optimization (SEO) to gauge the relative strength of a website’s backlink profile.

What constitutes a “good” or “average” Domain Authority can vary depending on your industry, niche, and competition. Generally speaking:

  1. A DA of 1-20 is considered low.
  2. A DA of 21-40 is considered below average.
  3. A DA of 41-60 is considered average to good.
  4. A DA of 61-80 is considered strong.
  5. A DA of 81-100 is considered very strong.

Keep in mind that what’s considered a good Domain Authority for your specific website depends on your goals and the competitiveness of your niche. It’s also important to note that Domain Authority is just one of many factors that can influence a website’s search engine ranking. Other factors like content quality, on-page SEO, user experience, and relevance to user queries are also crucial.

Factors like content quality, user experience, and backlink profile also play crucial roles in your website’s search engine rankings.

Additionally, keep in mind that Domain Authority can change over time, so it’s a good idea to check it periodically to monitor your site’s progress and identify areas for improvement.

How to Increase Your Domain Authority

Increasing your domain authority (DA) is an essential aspect of improving your website’s overall search engine visibility and credibility. Domain authority is a metric developed by Moz that measures the authority and trustworthiness of your website on a scale of 1 to 100, with higher scores indicating stronger authority. Here are detailed steps to help you increase your domain authority:

Create High-Quality Content:

  • Produce valuable, informative, and original content that addresses your target audience’s needs and interests.

How is Domain Authority Calculated?

Domain Authority (DA) is a metric developed by Moz, a company that specializes in SEO (Search Engine Optimization) and digital marketing tools. It’s used to estimate the overall authority or credibility of a website in the eyes of search engines like Google. While Moz doesn’t publicly disclose the exact formula used to calculate DA, they have provided some insights into the factors that influence it. Here’s a step-by-step explanation of how Domain Authority is calculated based on these known factors:

  • Collect Link Data: Moz’s algorithm primarily relies on data related to backlinks. It gathers information on the number of backlinks pointing to a specific domain and the quality of those backlinks. Backlinks are hyperlinks on other websites that point to the target domain.
  • Quality of Backlinks: Not all backlinks are created equal. Moz assigns more weight to backlinks from reputable and authoritative websites. This means that if a well-known and highly respected website links to your domain, it will have a more significant impact on your DA compared to a link from a less reputable source.
  • Link Diversity: The diversity of backlinks also plays a role. A variety of domains linking to your website is generally better than having all your backlinks coming from a single source. A diverse link profile indicates a broader range of interest and trust from different sources.
  • Linking Root Domains: The number of unique domains linking to your website is important. If multiple links come from the same domain, they are typically considered less influential than links from a larger number of unique domains.

  • MozRank and MozTrust: MozRank and MozTrust are two separate metrics developed by Moz. MozRank measures the popularity of a page on the web based on the quantity and quality of backlinks, while MozTrust measures the trustworthiness of those backlinks. Both MozRank and MozTrust are used as inputs in calculating DA.
  • Domain Authority Calculation: Moz uses a complex algorithm to process and analyze the collected data. This algorithm assigns a numerical value to each domain, representing its authority on a scale from 1 to 100. The higher the DA score, the more authoritative the domain is considered.
  • Comparative Analysis: Moz then compares the DA of the target domain to the DA of other websites in its index. It’s a relative metric, which means that your DA is calculated in relation to other websites in the Moz index. As the web evolves, the algorithm adapts to reflect the changing landscape of backlinks and websites.
  • Regular Updates: Moz regularly updates its DA calculations to provide the most current assessment of a domain’s authority. As new data is collected and analyzed, DA scores can change.
  • Keep in Mind: It’s important to note that DA is just one of many factors that search engines consider when ranking websites. It’s a useful metric for assessing the relative strength of a domain’s backlink profile, but it doesn’t guarantee high search engine rankings. Other on-page and off-page SEO factors also play significant roles.


Domain Authority (DA) is a metric used to assess the credibility and authority of a website. It’s calculated based on various factors, including the quality and quantity of backlinks. A higher DA typically indicates a more authoritative website, which can potentially rank better in search engine results. However, DA is just one of many factors that influence search rankings, and it should be considered alongside other SEO metrics for a comprehensive evaluation of a website’s performance.


Q: What is Domain Authority?

Q: How is Domain Authority calculated?

A: Moz calculates DA by combining information from its web index, including link counts, MozRank, MozTrust, and other metrics, into a machine learning algorithm that best correlates with rankings across the thousands of SERPs they predict against.

Q: Why is Domain Authority important?

A: No, a high DA score does not guarantee high rankings. DA is just one of many metrics that can indicate the potential for a website to rank. Actual rankings are influenced by numerous factors, including relevancy to the search query, user experience, and competition.

Q: Can Domain Authority change?

A: Yes, DA can fluctuate as the web evolves and as Moz updates their index. Gaining links from new high-authority sites can increase DA, while losing links or receiving links from spammy sites can decrease it.

Q: Is Domain Authority the same as Page Authority?

A: No, Domain Authority is a measure of the predictive ranking strength of entire domains or subdomains, while Page Authority (PA) measures the strength of individual pages. Both are scored on a scale from 1 to 100, but they assess different aspects of a site’s SEO potential.
