Abstract: A system and method are described for presenting on-line survey invitations to users over a network. The system enables selectively presenting survey invitations to users in accordance with a survey recruitment definition associated with a tag embedded within an on-line advertisement downloaded and executed on a user computer. If a determination is made by a survey recruitment server that a requestor is to be a potential control (unexposed) survey participant, then instructions are issued to the requesting user computer to obstruct presentation of the on-line advertisement which caused the issuance of the request for a survey invitation from the user computer.

Abstract: A system and method are disclosed for presenting on-line survey invitations to users over a network. The system selectively presents survey invitations to users in accordance with a survey recruitment definition associated with a tag embedded within a Web page (node) downloaded and executed on a user computer. A particular survey is selected from a set of presently active surveys applied by a survey logic server to received requests based upon a category (node ID) provided by a user computer in accordance with the execution of logic contained in the survey recruitment definition.

Abstract: A system and a method for measuring and monitoring effectiveness of on-line advertising are provided. The system and method provide a code attached to, for example, an advertising banner of a company that may advertise goods and/or services of the company. The code provides a signal to a server when the banner is viewed on a computer of a user. Cookie data is transferred by the server to the computer of the user providing information related to viewing of the advertising banner. Surveys are further presented to users to obtain information related to the effectiveness of the advertising for both exposed users and control users.

Abstract: A method and system for conducting an on-line survey involves communicating with a computer over a computer network and obtaining information indicative of an instruction to replace a set of links within a first web page with a link relating to taking an on-line survey. After replacing the set of links, when one of the replaced links is selected, a second page relating to the on-line survey is displayed. The second page includes a link to a page associated with a link replaced by the selected link, thereby enabling a user to easily continue to an intended page instead of taking the on-line survey.
