What is Domain Authority?There are countless websites, some are better than the others while some are still struggling. The question is that how do we get to know that which website is doing well, having a visibly solid reputation. Now you must be thinking that there must be some sort of criteria for judging that and you are certainly right. Domain Authority or DA is that statistical measure which is used to find out the reputation of a particular website which is provided by SEOmoz or better known as Moz. It is a statistical number from 0 – 100 which was developed by Moz in order to determine how does a domain rank in results of Google search engine. However, it is not the same thing as that of page authority. The difference between page authority and domain authority is rather significant as page authority is the ranking potential of a single web page whereas domain authority tells us about the overall ranking potential of the entire domain or subdomains.
