# Reporting on a Firebase AB test

A very popular use-case for our platform is to measure ongoing — or completed — [AB tests running in Firebase.](https://firebase.google.com/products/ab-testing) This article is to help you get started with measuring Firebase AB tests using the AdLibertas platform.

### Step 1: View the test in AdLibertas <a href="#h-step-1-view-the-test-in-adlibertas" id="h-step-1-view-the-test-in-adlibertas"></a>

When you have Firebase connected to AdLibertas you can automatically select and report on your Firebase AB tests. By default Firebase assigns a user property to each variant of the AB test, therefore we make it easy to run a report on these users over a timeframe of your choice. To do so, simply [create an audience](https://docs.adlibertas.com/the-platform/user-level-audience-reporting/advanced-audience-builder), choose Firebase Experiment, then choose the appropriate Experiment Name that’s running in Firebase.

In our example, let’s analyze a (fictional) test running that changes game complexity for new users.

Next, you can choose one (or more) variants for each audience.

### Step 2: Running Reports on a Firebase AB test <a href="#h-step-2-running-reports-on-a-firebase-ab-test" id="h-step-2-running-reports-on-a-firebase-ab-test"></a>

Once you’ve built your audiences, then you can [run reports ](https://docs.adlibertas.com/the-platform/user-level-audience-reporting/creating-advanced-user-level-reports)on these users over a timeframe of your choice.

Note: This will allow you to test your variants during, before, or after the actual timeframe.

![Choose the timeframe.](https://336314087-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FaO8orL32xNzJW4MhnNef%2Fuploads%2FQvxZnDNfFEkQ5ZI8h54w%2FScreen%20Shot%202022-12-28%20at%2012.50.54%20PM.png?alt=media\&token=02f6a021-164a-4e09-b3f4-9ae26b1c7191)

Once you’ve run the reports, you can measure the impact of these AB tests across multiple metrics and timeframes.

![You can add the count and averages for custom metrics to any audience, including a user's time in the app.](https://336314087-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FaO8orL32xNzJW4MhnNef%2Fuploads%2FQYFx595CyRTxa5M3IKKT%2FScreen%20Shot%202022-12-28%20at%2012.53.15%20PM.png?alt=media\&token=067a7ab6-d4ee-4b1b-982c-568fea520ebe)

Now you can explore the performance and behavioral differences through the standard Audience Reporting features
