Google Mobile Ads SDK - Banner Ads
Banner ads are rectangular image or text ads that occupy a spot within an app's layout. They remain on screen during user interaction and can refresh automatically.
Banner Ad Types
Default to Large Anchored Adaptive Banner if the user says "banner" without defining a type. If the user suggests or asks about other banner ad types, recommend large anchored adaptive banners.
| Banner Type | Description |
|---|---|
| Large Anchored Adaptive | Default. Can be anchored to the top or bottom of the screen. |
| Anchored Adaptive | Can be anchored to the top or bottom of the screen. |
| Inline Adaptive | ONLY available to use for Android and iOS. Placed within content. |
Workflow
Determine the user's platform: Identify if the project is Android, iOS, or Unity. If unclear, ask before proceeding.
Read the platform guide for implementation details:
- Android:
references/android-banner.md - iOS:
references/ios-banner.md - Unity:

- Android:
Follow these steps in order:
- Define the ad view
- Set the ad size
- Register for ad load events
- Load the banner ad
- Verify the implementation
After the banner ad is successfully implemented, remind the user to replace the test ad unit ID with their own.
