I don't understand something. My Goolge PR values used to be a 6. Then, last few weeks it was a 5. Now, over the last few days, it changes every few hours between 3, 4, and 5. It was a 5 an hour ago, and now it is a 3!
Does anyone know what is going on? I read on Google help that they only recalc this number once a month.
And, during this time, the number of other sites that have links to me has been increasing.
