PROBLEM TO BE SOLVED: To select interesting advertisement contents as banner advertisements. SOLUTION: The advertisement contents of an advertiser are grouped and presented to a client. The grouping is performed based on classification such as the type business of the advertiser or the type of a user under the consideration of a client layer (age layer or the like). When a certain client selects a certain advertisement group, and the client performs access to a certain specific contents providing site, the contents from the providing site and the advertisement contents in the designated advertisement group are displayed at a provider side. The advertisement contents in an advertisement group A are updated in a decided cycle such as a timely cycle, an hourly cycle, and a weekly cycle. The advertisement contents are previously selected at a client side so that the advertisement contents of the advertiser can be more efficiently advertised than the case of banner advertisements. |
