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.

China Search Engine Watch blogged about a demonstration by advertisers outside Baidu’s Beijing offices: (sic)

On August 4, 2006, some advertisers gathered outside Chinese search engine Baidu’s office building and demonstrate against its click faults. From the post boards presented by the demonstrators, it was said that 70% of clicks on Baidu’s paid ads were invalid. The claimed data was notarized by Beijing Notarization Bureau. The advertisers came to the building during lunch time and were expelled by the security guards.
