What is a Domain Authority? How is it Calculated?

Domain Authority tells you how well a website will rank on Google on a scale of one to 100. A high score indicates a website’s ranking ability to rank higher when compared to a website with a lower score.  

As a way of evaluating and studying the success of their digital campaigns, some companies and brands use Domain Authority (DA). The authority of some brands is apparent without any effort on their part. 

This is because their websites are naturally populated with certain keywords that carry some weight. For example, IMDB has a high Domain Authority due to the natural integration of relevant keywords throughout the site. 

Additionally, there is a high prevalence of related keywords. Knowing what terms you are deemed authoritative for will help you optimize your site more effectively. 

Keywords are only one factor, but your backlinks play an equally important role in increasing your domain authority. There is a logarithmic scale for determining domain authority. 

In other words, solo metrics will not always increase or decrease the score in the same manner. Despite its usefulness as a measure of a website’s relative position to its competitors, Google does not use domain authority as a ranking factor.  

Thus, Google does not use it to determine the position of a website in search results. Still, domain authority matters. Having a high domain authority increases your chances of ranking, while one with a low domain authority decreases your chances of ranking. 

While DA doesn’t directly affect rankings, it can be used to assess current performance and compare it to competitors – hence its usefulness in SEO.

How Does DA is Calculated? 

The Domain Authority is determined by evaluating several factors, including the number of links and the linking root domains, into a single DA score

After obtaining this score, websites can be compared and the “ranking strength” of a website can be tracked over time. As Moz also noted, Domain Authority does not influence search engine results and is not used by Google. 

Moz modified its DA algorithm in 2019 to incorporate a machine learning algorithm that predicts how Google ranks domains. A DA score can fluctuate as more (or less) data is entered into the software and more (or less) data is available for the learning software. 

For example, if a large site gained a lot of links, other sites’ DAs would decrease. It is because DA is based on machine learning and is compared to other websites. Thus, sites are always ranked realistically, as no site exists in a vacuum without other sites. 

Given the overwhelming web presence of large websites such as Instagram, Facebook, Twitter, and more, it is essential to look at DA as a relative value rather than an absolute value. 

You might not be able to achieve a DA score of 90 for any of your artistic profile websites. However, you might be able to learn how to rank like your favorite website.
