How can I earn from Adsense? This is the stats on one of my site. I am earning more from than that on my other site which has a lower traffic.
Possible invalid clocks. The amount for the clicks was not update happen to me before show a few clicks with zero earnings a hour later it showed.
123 clicks with 0 earning? It will be either fraud click or public service ads if not mistaken By the way, is this a new website?
It happens some time, may be someone intentionally clicking on your ads to get you banned from adsense. I think you should mail adsense team, and let them know about it, so at least you will be in safe position.
It can be many diferent things, can be the google "social" ads, maybe a campaign of Pay per 1000 views, but probably someone trying to get you banned from Adsense. You should contact Google as soon as possible. It have happend before to me and i contacted them and they say that its all under control and apreciated the warning. But you should contact them so you dont get banned. Best luck mate.
If there are invalid clicks (clicks from the same IP or proxy) then google will show clicks but will not give you any money.
