Click fraud is one of the most major issues in PPC advertising these days, and it is one which has to be confronted. Joe Holcomb, Senior Vice President at BlowSearch, is one of the people who is helping in doing so — and I truely support him.
If you have some spare time, I really recommend that you have a read of this article, and unlike other writeups on this topic, if you’re aware of search engine marketing and have some basic knowledge on online advertising, you won’t be lost half way through it — I can tell you that.
I have nothing further to add to this issue, except I just hope it ends someday, but then again, will it REALLY end? I would think not, click-bot programmers (kind enough? 😉 ) will always find another way, but then again, you can hardly predict.
