A wire story touches on the risks of Google's click-based advertising model.
"Mountain View, Calif.-based Google makes virtually all of its money from text-based advertising links that trigger commissions each time they are clicked on. Besides enriching Google, the system has been a boon for advertisers, whose sales have been boosted by an increased traffic from prospective buyers.Time will tell whether Google will be able to successfully combat this phenomenon.
"But sometimes mischief makers and scam artists repeatedly click on specific advertising links even though they have no intentions of buying anything. The motives for the malicious activity known as click fraud vary widely, but the net effect is the same: advertisers end up paying for fruitless Web traffic."
