I have no idea how the german manager-magazin.de thinks that it is really delivering a newsworthy story about fraud with the pay-per-clicks, since CNN already had this story 2.5 months ago?
I guess for some things I will always have to read international press in order to stay on top of things.
For those interested in a quick reminder: it is about companies hiring people, or using software, to have their competitors pay-per-click ads clicked on. The effect:
1) they increase the ad costs of their competitors,
2) once a certain spent-limit is used up, their competitors will not have the top spot of the list on certain keywords any longer.
