Tutorial: Test adoption of new AdMob ad formats

Step 4: Start the A/B test and review the test results in the Firebase console


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


Now that you have everything set up, you're ready to start and run your A/B test. While the test is running, you can review results in the Firebase console.

Deploy your app and start the test

  1. After you add the logic to handle the Remote Config parameter value (previous step), deploy the latest builds of your app that include them.

  2. In the Firebase console, start the A/B test by clicking Start Experiment.

Review results

  1. Firebase A/B Testing will run your experiment. After it's exposed users to the different variants, the Firebase console will display an improvement suggestion.

  2. Review how each variant performed based on the metrics that you selected during test setup.

    Firebase A/B Testing makes its judgement based on the primary metric that you selected, but A/B Testing also provides you with data for all the other secondary metrics that you selected. This allows you to take into account these secondary metrics when making a final judgement about the performance of a variant.

The image below shows an example of a test run with four variants, including the baseline (note that in this tutorial we kept it more simple with only two variants). In this example below, A/B Testing has determined that the winning variant is Variant A due to the improvements in the primary metric of Estimated total revenue.
