Tutorial: Test adoption of new AdMob ad formats

Step 5: Decide whether to roll out the new ad format


Introduction: Test new AdMob ad format adoption using Firebase
Step 1: Use AdMob to create a new ad unit variant for testing
Step 2: Set up an A/B test in the Firebase console
Step 3: Handle Remote Config parameter values in your app's code
Step 4: Start the A/B test and review the test results in the Firebase console

Step 5: Decide whether to roll out the new ad format


After letting the test run for several days or weeks, your app has probably supplied enough data for Firebase to construct recommendations.

If Firebase A/B Testing determines that the variant showing the new ad format is the winner, you can start showing the ad format to all users exposed to the experiment – just click the Roll out variant button in the A/B Testing page.

Alternatively, if Firebase determines a winner, you can end the experiment, then set the Remote Config parameter value to the winning variant's value. You can make this be the setting for all your users or even just a subset of your users.

However, if Firebase hasn't yet determined a clear winner, you can either continue running the experiment to gather more data, or end the experiment if it's already been running for a long period with inconclusive results.


And that's it! You've completed the tutorial for testing adoption of new ad formats using Firebase.
