MSN Custom Header

Back to Ad Specifications

The MSN Custom Header Ad takes advantage of the responsive design of MSN. An Advertiser can choose to display a single creative across all three page widths (2-, 3-, 4-column views), or can customize the creative for each of the page widths. The creative can re-animate on page resize, if desired. The user can hide the ad experience and then reopen it later, similar to the Billboard experience.
