Domain Authority, or commonly known as DA is a metric devised by Moz in order to establish how authoratitive a website is online. Domain Authority starts at 1 and finishes at 100 going by a logarithmic scale - meaning the higher domain authority, the harder it is to reach even further. For example, attaining a domain authority of 20, is a lot easier than getting a domain authority of 40.
If your website has a high Domain Authority, this shows search engines that your website has been around for a long time and is also trustworthy to show in the search engine results pages (SERPS).
