@Ahsan Mushtaq - Just since April 1st? It's not time to freak out yet. Read from here [webmasterworld.com...] to the end of last month's thread about SERPs then catch up to here... That help?
Is Panda now engaged with main algo?
By now it should have been. If they did it "correctly" and had pre-tested beforehand, like I think they did back in the middle of February, no one should notice any bumps in the road, just a little confusion.
I'm hoping it will become more like the old days, make a mistake and you'll feel it within a week.
