My pr went from 0 to 4 on December 31 And on January 8 it went from 4 to pr 2 . The pr drop did not hurt my earnings, but i just don't understand why this happened
first of all check your page rank in multiple tools. it is happened many time with many people that pr increased and then suddenly disappeared. But it will not affect your traffic that much.so..try to get more traffic . And if you are keeping regular update on your website you will regain your rank again soon.
