The Google PageRank is a numeric value that represents how important your page is on the web. It is based on the number and
quality of
"backlinks" a webpage has. A high PageRank indicates that the page must be important since many sites are linking to it.
Here is a small Python program to help you get the PageRank for your web page.
Usage
