What is it? How it works? It always shows 0 for my web page? why? What are the benefits of it? Is it necessary to check page rank? Thanks in advance. Kanna.
It is a rank used by Google to measure inbound link ranking. Your pagerank is 0 because IMO, you haven't build backlinks with sites with higher PR.
PR or Page Rank or the importance / trust of your site on web. basically, If you have a high pr it will help you on your link building. such as link exchange..
just focus on getting incoming links and don't worry too much about PR I sound like a broken record....I've probably posted that phrase 100 times today in different forums
PR is the No. of IB that Points on your site, and has a litle help in getting links if you have a high PR. But you must focust on your SERPS.
