Now, some of you may not even know you're committing, "fraud", but ignorance of the law is NO defense. When above your Google Adsense ads your text reads, "Please support our sponsors/advertisers", you’re duping the advertisers, as your guests will click out of sheer sympathy. The same goes for, "Support <insert site>! You’re asking your users to click.
Click the link above, read about the class action lawsuit, and know heads will start to roll. And remember, sh*t rolls downhill, so if you're using these tactics I'd stop immediately. And if you know of anyone else doing it, write them and let them know about it, especially if it's a friend.
If the advertisers aren’t receiving a positive ROI, eventually those Google Adsense checks will drop EVEN MORE than they already have.
