It looks like as of around today (1/11/2007) Google updated its PageRank and back link record. I noticed many sites’ with increased/decreased PageRank.
For those of you who are unfamiliar with checking the amount of Google back links – just type link:domainname.whatever into the Google search box.
The funny thing about Google PR is that it doesn’t seem to change real time like Alexa Ranking (check out alexa.org). One day a site can have 5/10 PageRank and the next it can be 0/10. One would think you could monitor a steady fall from 5 to 0.
