Domain authority is one of the main factors that define how well your website will rank in search engines. In the “old days”, a website was weighed based on its page-rank. Now, domain and page authority play a major role in the ranking of any domain.
I wanted to share this important topic with you because once you understand what domain authority (DA) is, you can start focusing on creating an authoritative blog.
Domain authority is a metric which was created by Moz (SaaS company), for the purpose of rating a website on a scale of 1-100, (100 being the best and 1 being the worst).
So the higher the domain authority of a website, the higher its ranking in search engines.
Instead of thinking of domain authority as a measure of your SEO effort, think of it as a competitive metric against other sites. So if you compare your website’s DA score with that of your competitor’s site, the site with the higher DA score is likely to rank higher in search engine searches!
DA consists of 40 ranking signals such as the number of links pointing to the site and the number of linking root domains – essentially the number of other sites linking to your site! (See MozTrust, MozRank , etc.)
DA measures the authority of the complete domain. Similarly, PA (page authority) is the measure of an individual page.
