Abstract: Systems and methods are disclosed for electronically generating targeted lists of customers and consumers. To generate the targeted lists, a marketplace search engine initially receives a keyword from a customer as part of a request for content related to the keyword. The search engine obtains and transmits the search results to the customer and then transmits to the customer an invitation to be included in the target list related to the keyword. The marketplace search engine then receives from the customer an acceptance of the invitation to be included in the target list, where the acceptance includes contact information for the customer. The engine addresses the request using the contact information and then transmits a confirmation request. Preferably, the search engine receives a confirmation of the acceptance from the customer; and then adds the contact information for the customer to the targeted list related to the keyword.

Abstract: Embodiments of the present invention are directed to a search engine system, method and apparatus comprising a search engine, a participant management system, at least one storage database, a listing database and at least one feedback mechanism. The search engine accepts input data and utilizes the input data to search for information related to the search terms. Upon retrieval of relevant information, the data analysis module organizes the data related to the search terms into a search results list. To determine the placement of listings upon a search request, the data analysis module determines the probability, for each relevant listing, that the user will ultimately complete the desired action if the listing is shown, wherein the probability of action is determined by a plurality of factors. This probability is then combined with the specific CPA for the advertiser.
