Domain Authority services are the Search Engine Ranking score of every website, which is assigned by Moz.

Domain Authority (DA) is a metric used to predict how well a website will rank on Google’s SERP. It was invented by Moz and is now an industry standard for all SEO marketers.

DA is measured from 1 – 100, with 100 indicating in high domain authority. The brand new website will always start with a 1, but the score will often improve with time and a proper SEO strategy.

Similar to DA, page authority (PA) is the metric used for individual pages within a domain. Put simply, DA covers your entire website, while PA covers a single page within your website.
