Yesterday we saw a hughe drop and it seems like it continues this day. Up to now we see -44% less traffic. This traffic is untargeted. Bounce rate is thorught the roof. And it looks like we have an -30 penalty.
It begann point 5pm yesterday CET. Hope that this is only a glitch.
My guess is that the testing in the last weeks between two different sets has been the allready inplementeed panda in main algo. The one was bad ever. Yesterday they switched to the panda set fully.
