Adsense didn’t allow own ads click. If you do this, your account will be disable. But accidentally it can be happen. Then what should to do??Let’s see, what Google Adsense official blog says-
As most of you know, our program policies state that publishers are not permitted to click on their own ads for any reason. For this reason, we’ve received many emails from publishers letting us know that they’ve accidentally clicked on their own ads. If you’re one of these publishers, we truly appreciate the efforts you’ve made to monitor your account and keep it in good standing. However, we do understand that an accidental click may occur from time to time, so there’s no need to contact us each instance this occurs.
So, don’t panic. If it’s a real mistake, you don’t have to worry.
