Abstract: Disclosed are an auction method and system, an advertising method and system, and a charging method and system, based on a bid price depending on a time period, and a fixed unit price depending on clicks or exposures. The advertising method may include verifying an advertisement exposure priority determined with respect to an advertisement of an advertiser, based on a period-based bid price which may be input from the advertiser, and exposing the advertisement of the advertiser during a time period corresponding to the period-based bid price, through an advertisement exposure region depending on the verified advertisement exposure priority, wherein an advertising fee depending on the exposure of the advertisement may be calculated based on the period-based bid price, a unit price per click (or a unit price per exposure) determined through an administrator system, and a number of clicks (or a number of exposures) which may actually occur during the time period.
