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.
- Unlike other rich media formats, an interstitial creative doesn't require a backup image.
Set up a single file for your interstitial creative. As you continue through this guide, look for more Try It! sections to help you build your own working interstitial unit.
