A charging method in a keyword advertisement in an online shopping mall using a CPT method is provided to charge according to margin conversion for only a user who shows a reaction after clicking. A server system of an advertisement provider is connected(S100). The server system demands input of a bidding price, a sales price, and a keyword to an advertiser terminal(S101). The server system stores the inputted bidding price, sales price, and keyword in a first DB(10)(S102). Margin rates of the bidding price are calculated and stored in a second DB(20)(S102). The margin rates of each advertiser are compared together(S103). The certain number of upper advertisements is knocked down according to priorities(S104). Advertising information of the advertisers is posed for certain time(S105). Clicking reactions of advertisements are calculated and stored in a third DB(30)(S106). A new bidding margin rate is calculated and stored in a fourth DB(40)(S107). |
