What is Google PageRank?

PageRank is one of the important ranking factors that Google uses to rank the web pages on the basis of quality and quantity of links to the web pages. It determines a score of a webpage’s importance and authority on a scale of 0 to 10. A webpage with more backlinks will have a higher PageRank than a webpage that has fewer backlinks. It was invented by Google’s founders: Larry Page and Sergey Brin.

Note: At present, Google is not using PageRank as a ranking factor or to rank a webpage.
