In one embodiment, a first search result responsive to a first search request is displayed in a presentation vehicle that is separate from a browser employed by an end-user to submit the first search request. The presentation vehicle may be a pop-under, for example. Upon detection of a second search request submitted by the end-user, the same presentation vehicle may be updated to display a second search result. In another embodiment, a presentation vehicle is employed to display a first content responsive to a first end-user behavior. An end-user behavior may be an activity that an end-user engages in while on a computer network. The end-user behavior may be navigation from one web site to another web site or submission of a search request, for example. The presentation vehicle may be updated to display a second content in response to a second end-user behavior.
