BusinessWeek has a great article about click fraud that I just read. I’d say there is definitely some reason for concern by Google, Yahoo!, and Microsoft after reading this. Users (advertisers) need to be given more control over where there ads are being shown. One suggestion I have is to let individuals “flag” sites that seem to be scams- usually a site that has nothing but ads on it. Once a site gets 3 flags (or whatever number Google decides on), the site should be prohibited from running ads anymore. I know Google wants to automate everything, but not everything in business can be automated.
In addition, this is a super interesting podcast that takes you deeper into the story.
