If you could steal a small amount of money from thousands of people you don't know and will never meet, have little to no chance of being caught, and make a lot of money doing it, would you? Me neither, but I think we are in the minority. I've been ranting about click fraud for years and proposed the adoption of "flat-rate" advertising as being the only realistic solution to the problem to Google and others many times. Well, the situation is there in many different forms just as it has been for years, yet no one seems willing to really do more than stick a few fingers in the dike.
Is Behavioral Targeting Being Used for Click Fraud?
by Steve Smith , Friday, February 5, 2010
Spyware was and still is the bane of neophyte PC users. I don't know how many times over the years I have been enlisted to cure the dysfunctional computers of my teen daughter and her friends. In every case, their youthful, shallow-pocketed pursuit of "free" anything online had led them to sites that inevitably clog their systems with spyware, which, once on a system, opens the door to all of its spy friends. It can take less than a month for a new PC to grind to a halt under the weight of all of those competing background processes.
But according to Harvard Business School Assistant Professor Ben Edelman, spyware and its behavioral tracking is also hurting marketers by contributing to click fraud. In research he published to too little notice last month, Edelman found that spyware surreptitiously planted on PCs was deliberately tracking users' browsing habits to see their likely purchase intent. The spyware knows what merchants the user already visits and likely buys from, and then the system "fakes a click" on the Google pay-per-click ad for the same merchant the consumer already uses.
"If the user proceeds to make a purchase - reasonably likely for a user already intentionally requesting the merchant's site - the merchant will naturally credit Google for the sale," Edelman says in his report. "Furthermore, standard optimization strategy will lead the merchant to increase its Google PPC bid for this keyword on the reasonable (albeit mistaken) view that Google is successfully finding new customers. But in fact Google and its partners are merely taking credit for customers the merchant had already reached by other methods."
One of Edelman's correspondents likens the practice to hiring someone to give out street flyers advertising an establishment. But then the rogue plants himself at the entrance to hand incoming patrons the sheet, effectively getting credit for "converting" existing customers.
Edelman says he tested for this problem on a virtual computer in his lab that was running the Trafficsolar spyware software. He used the PC to browse to sports apparel vendor Finishline.com. He was able to detect that Trafficsolar opened an unlabeled pop-up window that eventually redirected back to Finishline.com via a fake Google PPC click. The path between the spyware and Finishline.com is extremely complex, but Edelman says his screenshots and packet logs show the click being generated on the test PC without user interaction, hopping across seven or eight redirects.
If these schemes are widespread, then they undermine the trustworthiness of the PPC model in several critical ways, Edelman argues. First, it makes the advertiser pay for a customer it has already acquired. Then it encourages inflated keyword bidding by giving the advertiser the false impression the campaign is working well. And finally, it is producing an illegitimate click, one that the user never actually made.
Let's say the PPC was valued at $1. Each of the many intermediaries is passing along some share of the original Google fee to the network that redirected the traffic. By the time the original spyware vendor takes a cut, it is likely down to pennies. "The many intermediaries and their many fees, reinforce why this is such a terrible deal for the advertisers," Edelman tells me. "The advertiser agreed to pay a high price for traffic that was supposed to be valuable - worth the full $1 per click. Yet the ultimate seller [the spyware that originated the click path] is willing to sell it for just a penny or two, because the seller is selling something that just isn't worth it. But through the series of intermediaries, the advertiser nonetheless gets charged the high price for the low value placement."
It is hard to say how prevalent or widespread the offending spyware software is, but Edelman's tests suggest a number of intermediaries are happy to participate in this system. In the model he describes, behavioral targeting is turned on its head to work against rather than for advertising efficiency.
