Anyone know when was the latest PR update?
Well PR does means something if you're backlinking correctly. If you have a high PR and little traffic from search engines, then that means your backlinks obviously aren't targeting your keywords. By targeting I mean proper use of anchor text.
Well, one of the sites that went from 0 to 2 has 23 backlinks. These same backlinks have been used for at least 3 other sites that have many many other backlinks, which are PR0. The only thing in advantage for this site is domain age, that's the only thing I can come up with in its defense.
I have 784 sites and none have been updated yet.
