General notes

- web pages that do not exist in Google's database do not have a PageRank defined, hence their links are not taken into account on the computation of the PageRank values of other pages. Note that for a web page to be referenced in Google's database, there should exist a link pointing towards it from an already registered web page;

- links pointing towards web pages that include no other link (or towards web pages that do not exist in Goolge's database) are not taken into account on the computation of PageRank values;

- links from a page to itself are not taken into account.

(Click on the point representing the true PageRank value and move it around to see how the two scales are related)

You may find in the Internet several web sites that compute the PageRank value of any page, given its web address, in this logarithmic scale. Here are a few examples:
