Guys, but what about if I tell someone to click on every ad of the page, just once in every one of them? Will Google put me on "investigation" mode since that some user happened to want to click on every ad of the page? EDIT: It's still against the TOS? But a user could want to click in more than one link, if he doesn't click twice in the same one, that is.
If you're trying this desperately to get just a few clicks, perhaps you need to rethink your entire strategy. Or, if you're this paranoid about someone clicking on too many ads, perhaps you need medication.
It is against TOS. You cannot influence anyone to click your ads. A user can click as many ads he wants but if you're telling your girlfriend to click on your ads then she is clicking not because she is interested in them but because she was told to or want to "help you". She is not interested in the add content, she is not going to buy anything and these clicks will not convert into sales. That's a fraud and fastest way to get you banned. Best thing is not to tell your friends you earn with google ads. I've already seen threads here on DP of people who got banned, because they told their friends they earn money if someone clicks on their ads. And the friends tried to "help" them and were clicking every add on a page.
