Display a rewarded ad
This example demonstrates using the Google Publisher Tag (GPT) library to request and render a rewarded ad. Rewarded ad formats let app and web users receive rewards for viewing ads. Learn more about rewarded ads in the Google Ad Manager help center.
You can use the following GPT events to display and interact with rewarded ads:
| Event | Fired when... |
|---|---|
| RewardedSlotClosedEvent | A rewarded ad slot has been closed. |
| RewardedSlotGrantedEvent | A reward has been granted for viewing an ad. |
| RewardedSlotReadyEvent | A rewarded ad slot is ready to be displayed. |
| RewardedSlotVideoCompletedEvent | A rewarded ad slot has finsihed playing a video. |
For the purpose of this example, a simple modal dialog is used to both prompt the user to view the rewarded ad and to display the reward upon completion. In practice, it is the responsibility of the publisher to implement their own interface to accomplish these tasks.
Usage notes
To ensure an optimal user experience, rewarded ads are only requested on pages that properly support the format. Because of this,
defineOutOfPageSlot()may returnnull; you should check for this case to ensure you're not doing any unnecessary work. Currently, rewarded ads are only supported on mobile optimized pages where zoom is neutral. Typically this means the publisher has<meta name="viewport" content="width=device-width, initial-scale=1">or similar in the<head>of the page.Rewarded ads generate their own ad slot. Unlike other ad types, it's not necessary to define a
<div>for rewarded ads. Rewarded ads automatically create and insert their own container into the page when an ad fills.
