Create a banner ad unit

Banner ad units display rectangular ads that occupy a portion of an app's layout. They can refresh automatically after a set period of time. This means users will see a new ad at regular intervals, even if they stay on the same screen in your app. They're also the simplest ad format to implement.

Banner ad units can show the following types of ads: Text, image & rich media and Video. 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.

 

AdMob banner ad guidance

When you implement banner ad units in your apps, be sure to review the AdMob help center Policy section. You can get banner ad implementation guidance and learn more about the banner ad implementations we discourage.

The following steps will help you create a new ad unit in your AdMob account, then implement it in your app's code. You must complete all of these steps to start showing ads in this ad unit.

You may also set a custom refresh rate of 30-150 seconds or disable automatic refresh rate completely.
