Abstract: A mutually beneficial management system includes an advertisement database, a member database, a value adding module, an advertisement posting management system, an advertisement playing module, and a bonus module. The advertiser posts an advertisement via the advertisement posting management system and transfer money in the value adding module to pay the charge for advertising. The advertisement is stored in the advertisement database. The advertiser may assign the advertisement to be playable by members with specific conditions. When a website member clicks the advertisement, the bonus module sends a bonus to the member. The value adding module charges to an advertiser's account or credit card account as the advertising cost. The website member clicking the advertisement can get a bonus and be attracted to check the advertisement. The advertiser benefits from this because the advertisement can be set for specific consumers who may potentially purchase the products.
