Abstract: An advertising system identifies behaviors from user activity and associates the behaviors with a user profile. Advertisers provide the advertising system with information on conversion rates of users associated with user profiles. A behavioral model of user responses is built to identify the relative frequency of behaviors for increasing the response rate of ads. Incoming advertising requests are matched to modeled behaviors to determine an advertiser's interest in bidding on the ad placement.

Abstract: A video advertisement is presented to a user in a teaser video window overlaying a content page. When the user interacts with the video advertisement in the teaser video window, the teaser video window is expanded to a full-size video window over a predetermined amount of time. The video expansion is substantially smooth and the video continues to play in the window during the expansion. The full-size video window may be accompanied by a mini-site overlaying the content page, and providing additional information to the user. If the user interacts with the content page, the full size video window is reduced in size to the teaser video window and the user may interact with the content page.
