Guidelines for in-banner video creatives

In-banner video ads are HTML5 video creatives triggered within a standard display banner ad on a webpage. They usually follow standard Interactive Advertising Bureau (IAB) banner sizes (e.g., 300 x 250). Occasionally in-banner video creatives expand outside the initial dimensions of the banner (but only if initiated by the user). All standard display impressions are able to run in-banner video campaigns. 

In-banner video ads may be blocked and are only allowed on an impression if the Google Ad Manager publisher has opted in to specifically allow in-banner video ads to run on their inventory. Your bidder can identify if an impression does not allow in-banner video ads if the excluded_attribute field in the bid request includes VideoType: In-Banner Video (Publisher Blockable).

Types of in-banner video

The following in-banner video types are available:

  • Click to play: Creative initially displays as a static image, then the video plays once a user clicks on the creative.
  • Autoplay with no sound: Video automatically plays without sound until a user clicks on the creative.
  • Hover to play: Video plays after a user hovers over the creative.

HTML5 creatives for in-banner video ads can be hosted directly in Display & Video 360 provided they comply with generic display requirements.
