At the very least, we want to educate advertisers about the fact that in some sense they are being taken advantage of. Under the current mechanism, if they don't think carefully about their bidding strategies, they can end up paying a lot more to the search engines than they need to. |
Bidders could get away from the auction for days and weeks at a time and put their energy elsewhere. |
Companies would be much better off using such resources to enhance their products, improve customer service, or what have you. |
If some bidders are naive, and they bid the highest amount they're willing to pay, then they may end up overpaying. |
It's not a true Vickrey mechanism. |
Overall, this would stabilize the auction system. |
Remarkably, under this pricing scheme, it is optimal for each advertiser to bid his actual value per click, regardless of what other advertisers do. |
