How can we protect of click fraud? I noticed on this forum, many people get's banned by adsense. What monitoring software should we use, Please help.
The only thing you can do to monitor is watch your account daily. Don't go showing anyone your adsense sites, especially on forums such as this, Don't tell your family or friends about your sites, as I have heard of family members clicking on Adsense thinking they are doing the owner a favour!! I had the problem of explaining to my son when he was about 8 years old not to look at my sites at school with his friends.. (Yes he thought he would make his dad a fortune!).. Luckily he listened to me! Click fraud is rare to happen to you by a complete stranger, it does happen but it's rare.. As soon as you think you have someone doing this to you though, simply stop the adsense running on your sites and contact Google immediately.
Most people get banned by Adsense for breaking Google's TOS, not for click fraud, but this is a stupid practice, as many people seem naive enough to think that a company as big as G will not have systems in place to check for such things, it may take a while but you will get sussed. At the end of the day it is cheating, would you like it if someone tried to cheat you. Just my $0.02 Have a great day
