What is Domain Authority?

Domain Authority, better known in the SEO world as DA, is a scoring that foresees the probability of a website ranking in search engine results. It quantifies the ability of a domain to appear on search engine results pages (SERPs).

Domain Authority, originally developed by MOZ, is an analysis of a domain's ability to appear in SERPs compared to other domains in its niche. It uses the machine learning model to accurately predict the DA value.

Domain Authority considers over 40 factors to rank a website. The most important factors considered in predicting the DA score are the number and quality of backlinks your domain receives.

However, you need to keep in mind that this is absolutely not a ranking factor taken into account by GOOGLE, nor does it have any impact on your ranking.

Although DA is not considered by GOOGLE when ranking a domain, it is still an important metric to consider when optimizing your website for search engines. It is equally important to predict your domain's ability to receive organic traffic.

It is a noteworthy indicator for analyzing your domain's performance compared to others in your niche. It correlates with your SERPS. Straightforwardly saying, increasing your DA score will not improve your SERPs ranking in any search engine.

The DA score ranges from 1 to 100 and the higher the score, the higher the DA of that domain. Following its algorithms, it is easy to get a higher score if you are already on a lower ranking and difficult to get a higher score if you are on a higher ranking.

How is the Domain Authority calculated?

As mentioned earlier, the DA score is calculated by taking into account more than forty factors according to the MOZ algorithms. On a scale up to 100, with a higher score indicating more DA, the most important factor is the website's backlinking game.

For instance if you are receiving quality links and links to high quality websites, your link profile will be strong and help you get more points.
  • MozRank
    This factor takes into account which and how many websites you link back to. In other words, MozRank takes into account the quality and quantity of linking websites.
  • MozTrust
    As the name suggests, this evaluates the trustworthiness of your linking websites. The more credible the website you get a backlink from is, the higher your MozTrust factor and eventually your DA score will be.
  • Root domains
    Under root domains, how many different websites your domain is rooted on is taken into account. It is important to get backlinks from different domains because the number of backlinks from different websites contributes to the scoring of the root domain. However, a root domain only has a score if you are linked to from a domain, no matter how many times.
