I usually get 0-3 or so clicks a day, today it says I have 50. But no money. Should I email them or is this normal for some reason? There's no way I got 50 real clicks (it's really unlikely).
You should definitely report it to Google and if you see something similar happening today just take the ads offline for a while. Invalid clicks could get you banned.
I had a similar problem, and my solutions were: 1) Install Openads to track and block certain high clicking addresses and find the module that stops the ads being clickable after 3 clicks (per IP) And for the no earning, my problem was that I never put the domain in the allowed domains list, whether or not that applies to you, but I guess you may as well know
I reported it to Google. We'll see what they say if anything. I once clicked on my own ad and reported it. They said they weren't going to reverse the charge, and don't worry about reporting every little thing like that So they can be cool and see things in perspective.
Do you have any enemy in the business (adsense). Kindly go deep of it. Find out the cause. It is serious.
I can't imagine any enemies - like I said, 50 clicks would be highly unusual for me, and I have AS on 2 sites. I haven't gotten around to optimizing them yet so they're sort of taking up space. I know of no real competitors. My sites are in English. Oh well, I don't seem to have gotten any money, so I guess Google caught it before I did and at least I emailed them about it. Thanks for your replies.
If you have ads that "blend in" a little too well someone may have clicked one and got pissed off when they realized it was an ad then went back and clicked a whole bunch of times so that you wouldn't get paid for their click. It happens.
