One of the most important and influential SEO metrics many marketers, and specifically content marketers, pay attention to is Domain Authority (DA).
The Domain Authority metric was developed by Moz as a means of quantifying your website’s relative importance as a whole – its authority.
It provides an insight into the SEO “strength” of your website, and its likelihood of ranking for certain keywords. Essentially, the higher this number is, the higher you’ll rank in the SERPs, and the more traffic you’ll have.
