Interstitial build guide

Set up your files

How do I set up files?

Unlike other Rich Media formats, interstitial creatives can't use polite load. Interstitial creatives automatically wait for a page to load before they render on a site, and a polite load could delay the ad serving and create a poor user experience on the site.

To set up your files:
  • Create one SWF to be served as your interstitial creative.
    • The size of the creative can't exceed 1500x1500 pixels.
    • The size limit for interstitial creatives is 100K on most sites.

Studio reminder

  • Unlike other rich media formats, an interstitial creative doesn't require a backup image.

Try it!
