Hi,
As we all know many sites are now receiving "Zombie-ish" traffic that inflates the stats, and we don't know whether it's Google that is sending that traffic deliberately or not.
The problem is , I can't really find out whether Panda/Penguin has hit me until I get absolute real stats. OR , if one is receiving Zombie traffic, one should assume that his site has already been penalized ?
Also, if Penguin penalizes a domain, does the sub-domain also get penalized ?
