The page rank tool you see on your website is not just for decoration purposes. It is a very valuable indicator of webpage. I will like to start by simply defining page rank. Page Rank can be simply defined to as Google's View of the importance of a page. Many web surfers don't really know the value of the Page Rank Tool bar on most web browsers? The page rank tool on many internet browsers is a very important tool that helps website surfers to determine the importance of a webpage. The value of a Page Rank ranges from 0 to 10. From this grading, it implies that a webpage with a page rank of 0 or one is of little or virtually no importance to Google. But a website with a page rank of say 5 to 6 or 10 have very important information and by virtue of that very useful to users. A web page with a page rank of 10 contains useful stuffs and attracts a lot of visitors on a daily basis. Thus a webpage with a page rank of 10 is much more valuable than a website with a page rank of 5. On the other hand, a website with a page rank of 10 contains much more quality back link than a webpage with a page rank of 5. The Page Rank of a website measures not only the number of links that points to a website, but the quality of the websites that provides the links. Now this article will. For a website to have a high page rank, it must have a lot of quality back links. If a website contains a lot of useful information without containing quality back links, the website will definite rank low. The technology behind page rank is still hidden to many, although many seo gurus still believe that one can manipulate the page rank of a webpage. Yes this can really be done. It will only take one hard work and time. In summary, the page rank of a webpage is a measure of the importance of a page. Read more about Page Rank and How to Get High Google Page Rank

The basis of Google's search technology is indeed called PageRankâ„¢, and assigns an "importance" value to each page on the web and gives it a rank to determine how useful it is. However, that's not why it's called PageRank. It's actually named after Google co-founder Larry Page. Cheers Lucio Ribeiro
