What is site authority and why it is important

Domain or site authority is an indicator of important and trust by search engines.

It is a key a metric that can be used to understand how Google’s algorithms rank your site on the web. It basically measures credibility when it comes to search engine optimization.

The original metric was called Page Rank (or PR). It was created by Larry Page, one of the founders of Google. However in recent years it was eliminated by Google, leaving the SEO industry without a way to evaluate authority.

So Moz.com, a leading SEO tools company, developed its own Domain Authority measurement metric. It uses it as a way to gauge how your website would perform competitively when pitted against other websites in your area of expertise.

The Moz.com Domain Authority is a number assigned to each site based on a scale of 1 to 100 and consists of a mixture of 100s of SEO factors. It can be used to see how websites rank against each other in search results.

Among the many SEO factors, the key elements which make up the "DA" are – the website’s age, its popularity, backlinks (links from third party web sites), as well as MozRank and MozTrust which are Moz.com generated indictors of quality and credibility.

SEO tool competitor AHREFS.com has also created its own Domain Authority Index.
