What is Domain Authority

By | June 15, 2021

Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine result pages (SERPs). Domain Authority scores range from one to 100, with higher scores corresponding to greater likelihood of ranking.

Domain Authority is based on data from our Link Explorer web index and uses dozens of factors in its calculations. The actual Domain Authority calculation itself uses a machine learning model to predictively find a “best fit” algorithm that most closely correlates our link data with rankings across thousands of actual search results that we use as standards to scale against.

How is Domain Authority calculated?

Domain Authority is calculated by evaluating multiple factors, including linking root domains and total number of links, into a single DA score. This score can then be used when comparing websites or tracking the “ranking strength” of a website over time. Domain Authority is a Google ranking factor and has effect on the SERPs.

As of the Domain Authority 2.0 update in early 2019, the calculation of a domain’s DA score comes from a machine learning algorithm’s predictions about how often Google is using that domain in its search results. If domain A is more likely to appear in a Google SERP than domain B is, then we would expect domain A’s DA to be higher than domain B’s DA.

Since DA is based on machine learning calculations, your site’s score will often fluctuate as more, fewer, or different data points become available and are incorporated into those calculations. For instance, if facebook.com were to acquire a billion new links, every other site’s DA would drop relative to Facebook’s. Because more established and authoritative domains like Facebook will have increasingly larger link profiles, they take up more of the high-DA slots, leaving less room at the higher end of the scale for other domains with less robust link profiles. Therefore, it’s significantly easier to grow your score from 20 to 30 than it is to grow it from 70 to 80. For this reason, it’s important to use Domain Authority as a comparative metric rather than an absolute one.
