Dear friend, i have some experient developing a blog using expired domain and using WP platform. But recently i notice some my blog used WP go wild drop Page Rank quickly before 1 week age from 3/4 to 0/N/A. Yes from 5 blog using WP 3 domain PR drop to 0, and my friend from 3 blog drop 1. Contrary when i developed blog use Blogger, i notice that none of my blog drop PR after 1 month development. Now i back to basic to use Blogger to develop blog before i have correct answer about this. Does anybody here has the same experience? Or it's because of an other factors?
