Abstract: A system and method for collecting and processing user data over a network relating to a given advertisement. The invention displays advertisements on a given web page to a user running a web browser application on a client. In response to a user action such as clicking on the advertisement or moving the mouse cursor over the advertisement, a form is displayed to the user for input of data. The user may then input data into the form, and receive a new advertisement in the same location as the old advertisement upon completing the form. At no point is the user redirected to a new web page, nor does a new web page “pop up” over or under the current web page. The user inputted data is checked for accuracy and completeness, and may either be sent to the advertiser immediately or stored for future transmission. This data collection, processing, and delivery is all handled by the real-time communication within the original web page context.
