Overview of banner ads
Banner ads are rectangular ads that occupy a portion of an app's layout. They stay on screen while users are interacting with the app, either anchored at the top or bottom of the screen or inline with content as the user scrolls. Banner ads can refresh automatically after a certain period of time.
Banner ads are effective because they work well with many types of apps and don't take up much space. They're also the simplest ad format to implement.
Types of banner ads
You can implement Adaptive or Standard Banners.
|Standard||Fits only the specified banner size. Only ads that fit the specified size can be served.|
|Smart (deprecated)||Fills screen width on any device using a fixed height. This means the ad may appear small on some devices.|
There are two types of Adaptive Banners: Anchored Adaptive Banners and Inline Adaptive Banners.
Note: Anchored Adaptive Banners always return a constant size for a given device and width. This helps ensure a consistent user experience.
Also note that Adaptive Banners don't stretch, crop, or modify advertiser creatives.

More about Adaptive Banner ads
Adaptive Banners dynamically adjust the ad size for a variety of devices and screen sizes without excessive custom code.
How Adaptive Banners work
Adaptive Banners consider the device in use, the ad width you've specified, and the aspect ratios of all available demand.
For Anchored Adaptive Banners that are always on-screen, Adaptive Banners set an optimal ad slot size for each device. Once set, the anchored banner slot size doesn't change.
For Inline Adaptive Banners that are shown in scrollable content, the slot height reserved for advertiser creatives may change from one page-view to the next. This helps maximize eligible advertiser demand and improve revenue performance.
Adaptive Banners aim to fill the entire ad slot size, but select creatives for maximum performance. This means that ad creatives may fit edge to edge or be centered in the ad slot, depending on which advertiser bids highest for that impression.
You can use Adaptive Banner ads as a replacement for any Standard Banner placements.
Use Adaptive Banners in Ad Manager
Make sure your Ad Manager setup is optimized for adaptive sizing:
- Confirm that ad contraction is enabled.
- Configure your line items as described in Match size ranges in Adaptive Banners.
