Ad units, ad formats, & 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 will look in your app and where they'll be located. Ad type describes the kinds of ads an ad unit can show to users.

There are several ad formats to choose from, and each ad format specializes in showing different ad types.

Ad formats

Banner: A basic ad format that appears at the top & bottom of the device screen.

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 (eg. user interactive).
  • 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.

The ad types available to an ad unit depend on the ad format you selected when creating it.
