One Internet business model is the brokerage model. At the heart of this model are third parties known as brokers, who bring sellers and buyers of products and services together to engage in transactions. Normally, the broker charges a fee to at least one party involved in a transaction. While many brokers are involved in connecting consumers with retailers, they also may connect businesses with other businesses or consumers with other consumers. A wide variety of different scenarios or business configurations fall under the banner of a brokerage model. These include everything from Web sites posting simple online classified ads and Internet shopping malls (Web sites that sell products from a variety of different companies) to online marketplaces, online auctions, aggregators, and shopping bots.
the infomediary model is characterized by the capture and/or sharing of information. The simplest form of an infomediary model is the registration model. In this scenario, companies require users to register before gaining access to information on their Web sites, even if the information itself is provided at no charge. One possible scenario for this example involves companies that offer white papers, or expert articles containing valuable advice, to Web site visitors. These white papers usually are written by the company's experts, who are available as consultants. Registration is a condition for viewing or downloading the articles so the company can capture contact information and other data from the interested party and use it to make sales calls and potentially acquire new clients for its consultants.
Companies using an infomediary model also may be third parties that provide products like free computers or services like free Internet access to consumers in exchange for information about themselves. This information is then sold to other companies who use it to develop more sophisticated, successful marketing campaigns. The information collected commonly includes things like product and service preferences; buying habits; and demographic details like age, sex, and income level.
