Google update 29-30 march I think those dates there were any changes. In my case most of my sites are down. Visits and revenue are more than 50 to 70 percent less after this date.
I thought something was going on because six of my sites had traffic jump sky high and it hasn't stopped yet.
My sites are still in same position. Hopefully I am lucky enough coz some other sites got ranked this time.
One of my sites disappeared from all rankings for a day, came back to the same place. Others all climbed in rankings. Adsense income up as well. No complaints here.
It's the weekly "My site moved, must be a Google update" thread! Just stop with these threads unless you have a real source about a google update. If you just want to know if other sites also moved check www.mozcast.com
Yes, I know some guys got the penalty very soon, even when their sites were just built a few backlinks.
