Overview of rewarded interstitial ad units (Beta)

Rewarded interstitial is a new type of incentivized ad format that allows you to offer rewards, such as coins or extra lives, for ads that appear automatically during natural app transitions.

Unlike rewarded ads, users aren’t required to opt-in to view a rewarded interstitial.

Instead of the opt-in prompt in rewarded ads, rewarded interstitials require an intro screen that announces the reward and gives users a chance to opt-out if they wish to do so.

Only skippable ads will be served in rewarded interstitial ad units.

Currently, this includes demand from AdMob and Meta Audience Network. Mediation with other ad sources is not currently supported, but may be added in the future.

How do rewarded interstitial ads work?

Rewarded interstitial ads can serve without requiring the user to opt-in to viewing. At any point during the experience, the user can decide to skip the ad or to stop viewing the ad. 

You can specify the reward values associated with the ad units in your app and set different rewards for different ad units. Users will receive the reward for interacting with the ad without needing to install anything. 

Introduction to rewarded interstitial ads

AdMob rewarded interstitial ad format & features

Before displaying a rewarded interstitial ad to users, you must present the user with an introduction screen that includes the following:

• Clear reward messaging that incentivizes users to view the ad 
• A clear, unobstructed option to skip the ad before it starts
• Sufficient time for the user to understand the reward and opt-out if they don’t want to view the ad

Example

A user playing a game has just completed a level. While the next level loads, the user is prompted that an ad will begin in a few seconds and the reward for watching the ad is an extra heart. The user has the option to close the ad. 

After a few seconds, the ad begins with a countdown that lets the user know how much time is left until they receive the reward. If the user clicks to exit the ad, a prompt appears to warn about the loss of the reward. The user must confirm that they want to exit the ad before the ad closes.
