What is PageRank and why does it matter?

Hi Friends,
PageRank (PR) is a mathematical formula that judges the "value of a page" by looking at the quantity and quality of other pages that link to it. Its purpose is to determine the relative importance of a given webpage in a network (i.e., the World Wide Web).

Page rank is the measure of the popularity of your webpage given by Google. It is of no value today as Google has stopped updating its page rank algorithm.

PageRank is an algorithm used by Google Search to rank web pages in their search engine results. PageRank is a way of measuring the importance of website pages

Page rank is important because it's one of the factors a search engine like Google takes into account when it decides which results to show at the top of its search engine listings – where they can be easily seen. (In fact PageRank is a Google trade mark – but other search engines use similar techniques.)
