I think someone has been click attacking one of my sites.. the past 3 or 4 days ive been getting multiple clicks on some of my sites with very little income resulting from them... generally its 3-6 clicks and Im only earning what I would usually earn from 1 click....... And the clicks seem to be on the same channel. Anyone know how i could figure out if someone is doing this to me on purpose??
When you get less impressions and alot more clicks, that is when you should contact google to know about it.
visitors may clicked ads but just closed the windows i think. but better check with your stats , referrer
Doesn't sound like much to worry about yet. Just keep an eye on it and let Google know if it gets worse.
