Collapsible banners initially show the selected banner placement as a larger overlay with an option to collapse the expanded banner to a standard banner size. The collapsible banner ad is the only format that allows users to minimize an ad, giving them control of their experience.
Collapsible banner ads also offer more room to convey the advertiser’s message, which provides better visibility and higher click-through rates.

Get started with collapsible banners
Apps that have some static user interface screens (like utility apps or game information screens) are a good fit for collapsible banner ads. You can use them in any existing banner ad placements, such as content loading screens, end of game screens, or any other page transitions.
To implement, you don't need to create a new ad unit or ad slot. Simply add an extra parameter to an existing anchored adaptive banner slot to request a collapsible banner ad to show. Learn more about implementing collapsible banners for Android, iOS and Unity.
