Define Pagerank

Page rank is the value of page that determines its importance on the web. To promote our website or to get higher page rank we do link building for our website. Google figured that when one webpage is linked to another webpage, it becomes effective in casting a vote for the other page. The more number of votes that are cast for a page, the more importance the page gains on the web. The page with more number of votes is given a better page rank by google.It is not the only factor by which google gives a page rank to a website but it’s an important factor.
