In existing keyword auctions, the number of slots is determined in advance and the obtained social surplus is not always maximized. Thus, we develop new keyword auction protocols in which the auctioneer can flexibly determine the optimal number of slots which maximizes social surplus. First, we propose an auction protocol based on the Vickrey-Clarke-Groves mechanism. While the VCG can satisfy theoretically good characteristics, it needs the complicated calculation of payment.
