When you select the ad types for an ad unit, you're selecting the kinds of ads you want to allow it to show users. When the ad unit requests an ad from AdMob, it can only receive an ad that matches one of its assigned ad types.
- Text, image and rich media: Text, image, HTML5/rich media ads. Could be text only, static images, animated images (.GIF) or rich media (such as interactive ads).
- Video: Ads with video and audio content. Video ads that appear in banner ad units always start muted. Users can unmute the ad if desired using the mute button provided by Google.
- Interactive: Ads with an interactive element, such as a playable ad or a survey.
The ad types available to an ad unit depend on the ad format that you selected when creating it.
