Expandable banners provide a user-initiated panel to extend the ad beyond standard unit ad dimensions. The expanded panel allows extra space for guests to interact with the advertiser's message without leaving the page. Panel expansion direction in relation to the creative will be based on site's requirements and where the ad units are positioned on the page.

The expand may be initiated on roll-over or on-click. Whichever method is used, the same method must be used for closing the expand panel in order to maintain a consistent guest experience. The expanded ad unit must include a close button.

Expandable ads approved for the following ad sizes:

  • 728x90
  • 300x250
