Since the Google Page Rank Update from 26.10.2007 I have detect some major changes in the way the Page Rank is distributed over the directories from the Website Submitter. I have run some comparison in my tests.
Number of directories: 3574
Directories type: free, paid, reciprocal, regional
|Before Google PR update||After Google PR update|
You can observe based on the date before the Google update and after a big difference between the way Google PR is distributed over these directories. Infact we can call it a downgrade, the number of directories with PR0 before the Google PR update was 357, after the PR update the number increased to 1207. I have displayed bellow in a graphical mode the distribution of the new Google PR and the PR fluctuations.
