Hmm. I'd probably do whatever it takes to dissuade them from clicking your ads, just to be safe.. Something like 'people I know aren't allowed to click my ads, because a) Google will cancel my account and b) I'll beat your ass'
Just tell them the truth. Say you do get paid per click but you don't want your visitors to aimlessly click on ads because that drained advertisers budgets and could flag your account for click fraud. You can also refer them to the Adsense TOS if you like.
Yep, do not respond. This way you will have nothing whatsoever to do with it in the event this guy makes a click attack.
Reply with: Thank you for taking your time and giving me important feedback. Google advertisements are paid advertisements. However, it will not generate revenue if you click on them for no reason, but if you find an attractive website displayed, feel free to visit it. Half the truth
So where did he ask you from? In a public forum or private email? If it's PM, you should just tell him "it's advertising" and leave it at that. If it's in a private forum where anyone can see it, you should DELETE the thread immediately, then PM him and tell him "it's advertising" and tell him not to ask in a public forum again and leave it at that. I can't stress enough how easily, EASILY this can get you banned. Unless your site is about CPC/web marketing (i.e. like DP) there is simply no reason for you to mention your ads, and doing so will get you banned.
I would just send them to either Adsense Quick Tour or the Adsense Blog and leave it at that. That should cover your bases.
Well If you have time then ask him in return: "Which site brother?? I have 2200 sites and all have adsense and I earn atleast 10 from each of them daily. So I am very busy guy just let me know for which site you are talking about." LOL And he will not respond I think.
Tell 'em to click away....just kidding. Best to not respond to this kind of email. If the person wants to know enough about the ads, he/she could simply go to Google to learn about them.
visitors are the gods treat them good they will make you rich don't tell his to go to google and ask better try to make him clear how this work and ask him if he is interested ,and give hands to help him he'll never forget you he'll tell his friends and his friends will do the same , this is just a way of promotion and you have more money
