Domain Authority (DA) is a metric that every website owner should understand, first developed in 2016 by Moz. Most people don’t have a grasp on how it works. The simple explanation is that DA is a measurement of the popularity and trustworthiness of a site. This is based on factors like the number of unique links to it, the number of referring sites, content quality, and social signals (when content related to the domain is liked, shared or commented upon in its social channels).
Why Should I Care About Domain Authority?
The purpose of the DA metric is to measure how well a site performs in SERP results and ranks against its competition. For the website owner, you can use this metric to help you understand how competitive a particular URL is or to gain insight into how much traffic a competitor might receive. For search engines, the metric helps them decide whether or not to refer traffic to a site and how high (or low) to rank that site in SERP results.
Domain Authority is calculated by evaluating several different factors, including linking root domain and total number of links into a single DA score, which can then be used when compared against other sites or tracked over time.
How Can I Find the DA Score of a Website?
There are a number of tools you can use to check Domain Authority, including:
As of the Domain Authority 2 release in January 2019, the calculation of the DA score comes from a machine learning algorithm’s prediction about how often Google is displaying a site in its search results. If a site appears more frequently in Google’s search results, then we would expect the DA of that site to be higher than another site that does not appear as much.
