Tony Hill and a Digital Point forum thread has recently reported an interesting bit of news. The news is that Adsense is now showing its publishers, the money they have taken for all the invalid clicks. Although it is a great move by Google, but keep in mind Google is not going to give you the money back. Next time just keep an eye on the invalid clicks.
Tony writes, "I suspect that they have been doing this behind the scenes. I’m surprised to see something like this. Some people suspect AdSense may cut back on the banning and instead just show you how much they are taking away from you. This leads me to beleive it will give the publisher more of an incentive to STOP clicking on their ads because they will realize Google isn’t stupid and will take the money back."
