PURPOSE: An advertising method using a free gift having a fixed winning probability is provided to enhance advertisement effect by accumulating a predetermined reserving money to a user who watched an advertisement and selecting and applying a prize winning probability free gift. CONSTITUTION: An advertisement requested by an advertiser is stored in an advertisement information database being linked with an advertisement server(S110). An advertisement server operator receives an advertisement charge from the advertiser and stores a prize winning probability in a prize winning information database(S120). The advertisement server operator notifies a stored advertisement and prize winning information in an operating site(S130). If a user watches the notified advertisement, a predetermined reserving money is accumulated and stored in a user information database(S140). If the user selects and applies to a predetermined free gift by using the stored reserving money, the money corresponded to the amount subscribed is subtracted from the reserving money(S150). If the application in accordance with a prize winning probability of an applied free gift is completed, a lot is performed(S160).
