Create an ad unit

These instructions apply to existing apps you're already monetizing in AdMob. To create an ad unit for a new app, see Monetize a new app.

Complete the following steps to create an ad unit for an existing app.

  1. Sign in to your AdMob account at https://apps.admob.com.
  2. Click the Monetize tab.
  3. Select your application from the All apps list on the left-hand side.
  4. Click + New ad unit.
  5. Click Banner, Interstitial, Rewarded interstitial, or Native.
  6. Provide the following details for the ad unit:
      Banner
    • Ad type: Choose the ad type(s) allowed for this ad unit. You can choose any combination of text and image by checking the boxes. Checking both boxes is recommended since unchecking either of the boxes might limit the revenue generated by the ad unit. Unchecking all of the boxes will result in an error. You must choose at least one ad type for each ad unit.
    • Automatic refresh Determine how often a new ad impression is generated. You can choose not to refresh or to refresh ads every 30 to 120 seconds. We recommend setting a refresh rate between 45 and 60 seconds.
    • Text ad style: Select a text ad style that complements your app. You can use the standard style or customize your own style.
    • Ad unit name: Enter a unique name and description that will help you find this ad unit later (e.g., Top Banner on Home).
    Interstitial
    • Ad type: Choose the ad type(s) allowed for this ad unit. You can choose any combination of text, image, and video by checking the boxes. Checking all three boxes is recommended since unchecking some of the boxes might limit the revenue generated by the ad unit. Unchecking all of the boxes will result in an error. You must choose at least one ad type for each ad unit.
    • Frequency capping: Choose whether or not to set a cap on the number of impressions you want to allow to show to each user. Limits the number of times ads are shown to the same user per minute, per hour, or per day for a given ad unit.
    • Ad unit name: Enter a unique name and description that will help you find this ad unit later (e.g., Interstitial on level complete).
    Rewarded interstitial

    You can use rewarded interstitial ad units to reward users with in-app items for watching video ads. You can specify the reward values and units associated with the ad unit’s placement in your app and set different rewards for different ad units. Rewarded ads are only available from third-party networks that you've selected for mediation.

    • Ad type: Rewarded interstitial ad units are limited to video ads only.
    • Rewarded settings: Choose whether to manually set the reward (such as, amount and item) or whether to use third-party network settings instead. If you manually set the reward values, they will override any values provided by third-party ad networks.
    • Reward amount: Enter the number of reward items the user will receive. Must be a whole number.
    • Reward item: Enter the name of reward item the user will receive. Examples: Coins, extra lives
    • Frequency capping: Choose whether or not to set a cap on the number of impressions you want to allow to show to each user. Limits the number of times ads are shown to the same user per minute, per hour, or per day for a given ad unit.
    • Ad unit name: Enter a unique name and description that will help you find this ad unit later (e.g., Coin Reward).
    Native

    Native express ad units are custom designed to match the look and feel of your app's user experience. We've created a separate set of native ads express guides to help you get started.


  7. Click Save. You'll see the ad unit ID for this ad unit.
  8. Click Done to return to the Monetize tab or click Send an email with these instructions to have instructions sent to you via email.

You've now created an ad unit for your app. To display ads in your app, follow the detailed instructions to incorporate the SDK into your app (for Android, iOS, or Windows Phone).


Example code
Currently, you can create up to 100,000 ad units per app.
