Test creative types

AI-generated Key Takeaways

• Google Mobile Ads SDK allows you to specify a desired creative type for test queries using the ft_ctype request parameter.

• This parameter restricts the ads returned to the specified creative type for easier testing in test mode, affecting only Google ads.

• Using this feature might increase the chances of no fills as it limits the available ads.

• Mediation is not supported with this feature, so test with an ad unit without mediation enabled.

• Reservation inventory and backfill-only ad units may need additional configuration to ensure accurate testing with ft_ctype.

Select platform: Android iOS

Google Mobile Ads SDK provides an API that lets you specify a creative type for test queries. When the parameter is set, only creatives of the specified type are retrieved and rendered.

Important: This feature doesn't apply to reservation inventory, which may still serve if not explicitly disabled for the specified slot. We recommend that you test with a backfill-only ad unit.

Usage

To specify a creative type, include the ft_ctype parameter in an extras object and pass it to the ad request. This may restrict which ads are available and result in no fill.

Note: The ft_ctype parameter only works in Test Mode.

Kotlin

val extras = Bundle()
extras.putString("ft_ctype", "video_app_install")

val request = AdManagerAdRequest
  .Builder()
  .addNetworkExtrasBundle(AdMobAdapter::class.java, extras)
  .build()

Java

Bundle extras = new Bundle();
extras.putString("ft_ctype", "video_app_install");

AdManagerAdRequest request = new AdManagerAdRequest
  .Builder()
  .addNetworkExtrasBundle(AdMobAdapter.class, extras)
  .build();

The following table lists the valid values for ft_ctype:

Creative Type	ft_ctype	Format
HTML5	html5	Banner, Interstitial, Rewarded
App install image	image_app_install	Banner, Native, Interstitial, Rewarded
Display image	image_display	Banner, Interstitial
Display partial slot	partial_slot	Banner, Native, Interstitial
App install text	text_app_install	Banner, Native, Interstitial
Display text	text_display	Banner, Native, Interstitial
Trueview	trueview	Interstitial, Rewarded
App install video	video_app_install	Banner, Native, Interstitial, Rewarded

This feature impacts Google ads only. If your ad unit enables mediation, ads returned from third-party ad sources don't respect the ft_ctype parameter. We recommend testing with an ad unit that doesn't have mediation enabled.
