It would seem that whilst I was in a cave this weekend, Google decided to start a pagerank update. While not all the Data Centers seem to be updated just yet, it’s clear that a few are already. If you don’t know what PageRank is, don’t be to ashamed, I didn’t know once. Basically, it’s a measure of the popularity of a site address according to a Google algorithm. The measure is out of 10, so a 0/10 is the worst and a 10/10 is the best. I should mention that all sites begin at 0 so it can sometimes mean that the site is new.
On a personal site note, this site seems to be staying at PR5 while the new addresses for A Penny Saved and eBay Habit are moving up to PR2 and PR3 respectively. I find that interesting as the penny-saved.com address has about 2-3 times more incoming links than the ebayhabit.com address. So, I can guess that traffic must make a bit of a difference there as well as ebay habit makes about 1.3 times the traffic.
Did your site get updated or downgraded?
