The interstitial is a full-screen ad format that launches before displaying a publisher's content. It usually launches with an overlay that resizes to the dimensions of the screen, closes after a defined period of time, and optionally, disables scrolling of the publisher's page.

The interstitial includes the following attributes:

  • Maximum size is 10 MB. (The initial load can be set at 300 KB.) For more information, see

    Add polite load to your HTML ads.

    Note

    Notes:

    • While Amazon Ad Server (AAS) ads can be up to 10 MB, ads must also follow the specifications of the publishers or DSPs that will ultimately run the ad.

    • Maximum ad size can be increased beyond 10 MB upon request; however, you should check with your media partner to verify that the ad will not be rejected by the publisher.

  • Ad can contain multiple user interactions.

  • Ad can contain video.

  • Ad is displayed at the bottom right corner of the page when the option Enable the Dynamic Expansion Direction is selected.

Note

Note: This format is not supported in unfriendly iFrames.
