About ad units, ad formats, and ad types
- Ad units are containers you place in your apps to show ads to users. Ad units send ad requests to AdMob, then display the ads they receive to fill the request.
When you create an ad unit, you assign it an ad format and ad type(s).
- Ad format describes the way ads appear in your app and where they'll be located.
- Ad type describes the kinds of ads an ad unit can show to users.
Ad formats
There are several ad formats to choose from, and each ad format specializes in showing different ad types.
How to choose the right ad format for your app
For subtitles in your language, turn on YouTube captions. Select the settings icon at the bottom of the video player, then select "Subtitles/CC" and choose your language.

Ad types
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 rich media: Text, image, HTML5 / rich media ads. Could be text only, static images, animated images (.GIF), or rich media (such as interactive ads). Note: Animated images (.GIF) are not supported for native 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.
- Ad pods: You can use ad pods for rewarded video ads. Ad pods serve 2 back-to-back videos during a single impression. Ad pods are included by default, but you can turn them off by unchecking the Ad pods box in the Advanced settings of your rewarded ad unit. Excluding this ad type may impact ad revenue.
- Interactive: Ads with an interactive element, such as a playable ad or a survey.
