Today was major Google page rank update.
Most of our blogs increased their page rank – from pr0 to pr3/2/1, from pr4 to pr5, from pr3 to pr4.
Some of the blogs lost page rank as well.
Our conclusions – Google gave priority for old aged blogs with a lot of indexed pages, number of Google back links and freshly updated unique content.
Another factor that helped – we built links for our blogs considering different c-class Ips.
