Emma Connors and Mark Jones have written about click fraud in today’s Australian Financial Review. Unfortunately the article cannot be viewed online for free. They write that Nielsen/NetRatings is starting research into this issue in Australia. They are going to look at the behaviour of IP addresses, exactly what I said in the same article!
Also quoted is ClickSentinel, which claims that 30% of clicks are fraudulent. I wonder if Shuman Ghosemajumder’s team at Google will look into this claim next. 🙂
Try this service if you are having problems with click fraud – ClickProtector – it detects fraud and it is pretty cheap too. It has a way to try and get money back from the Tier 1 and many of the Tier 2 search engines, including Google and Yahoo etc. They have a pretty cool feature wher eyou can make an unblockable popup come up on the screen of the offending clicker. I dunno… works pretty good for my sites!
