Get started with Google Analytics

Google Analytics is Firebase's analytics engine that gives you access to powerful insights into your data. Start using Google Analytics in your app by adding the Firebase SDK for Google Analytics.

Why add the Firebase SDK for Google Analytics?

With the basic AdMob setup, you can view aggregated statistics from automatically collected events and user properties in the Analytics dashboard of the Firebase console without adding any additional code to your app.

However, if you want to collect additional custom event data or user properties, you'll need to use the Firebase SDK for Google Analytics. With this SDK, you can log up to 500 different analytics event types, and there's no limit on the total volume of events your app logs. An example use case for logging custom events is to include data in your revenue calculation from a custom event called ecommerce_purchase to help you better represent ARPU and ARPPU metrics.

By adding the Firebase SDK for Google Analytics, you can also add custom conversions for ad campaigns and enable the use of other Firebase products.

The following steps describe how to start using the Firebase SDK for Google Analytics in your app. After initializing the SDK, visit the Analytics documentation to learn how to start logging events in your app.

Step 1: Add a configuration file to your app

If you registered your app with Firebase before creating an AdMob link, then you already added a Firebase configuration file to your app. Check for a GoogleService-Info.plist file in the root of your Xcode project. Also make sure that the config file is added to all targets.

If you don't have this config file in your app, expand this section to learn how to add this file.

1. In the Your apps card of your settings > Project settings, select the bundle ID of the app for which you need a config file.

2. Click Download GoogleService-Info.plist to obtain your Firebase iOS config file (GoogleService-Info.plist).

   • You can download your Firebase iOS config file again at any time from your settings > Project settings.

   • Make sure the config file name isn't appended with additional characters, like (2).

3. Move your config file into the root of your Xcode project. If prompted, select to add the config file to all targets.

If you have multiple bundle IDs in your project, you must associate each bundle ID with a registered app in the Firebase console so that each app can have its own GoogleService-Info.plist file.

Step 2: Add the Firebase SDK for Analytics to your app

1. Add the dependency for the Firebase SDK for Google Analytics to your Podfile:

   pod 'Firebase/Analytics'
   

2. Run pod install, then open the created .xcworkspace file.

3. Import the Firebase module in your UIApplicationDelegate:

   Swift

   import Firebase

   Objective-C

   @import Firebase;

4. Configure a FirebaseApp shared instance, typically in your app's application:didFinishLaunchingWithOptions: method:

   Swift

   // Use Firebase library to configure APIs
   FirebaseApp.configure()

   Objective-C

   // Use Firebase library to configure APIs
   [FIRApp configure];

Implement custom event logging

This section shows an example of how to implement custom event logging in your app. This specific example is for the custom event ecommerce_purchase which is a helpful event to log for AdMob-linked apps, especially for calculating ARPU and ARPPU.

Why is ecommerce_purchase important for ARPU and ARPPU?

A key metric for your app is revenue by user, which can be further segmented into ARPU and ARPPU. These two metrics display in the User metrics card of your AdMob account and in the Analytics dashboard of the Firebase console. Revenue, though, isn't directly measured; instead, it's the sum of your estimated AdMob earnings and the following two analytics event values:

• in_app_purchase: when a user completes an in-app purchase that is processed by the App Store on iTunes, like an initial subscription, unlocking premium services, or buying in-game items

• ecommerce_purchase: when a user completes a purchase, like online shopping, buying coupons or discount items, or buying movie tickets

Without any additional code in your app, the Mobile Ads SDK automatically collects analytics data for in_app_purchase events. However, if you want to also include ecommerce_purchase event data in the revenue calculation, you'll need to implement custom logging via the Firebase SDK for Google Analytics.

Here's how to implement custom event logging in your app:

1. Make sure that you've completed the Get started with Google Analytics section of this page, which includes configuring your app to use Firebase, adding the Firebase SDK for Google Analytics, and initializing the SDK.

2. Log an ecommerce_purchase event (Swift | Obj-C). Here's an example:

   Swift

   Analytics.logEvent(AnalyticsEventEcommercePurchase, parameters: [
     AnalyticsParameterCoupon: "SummerPromo",
     AnalyticsParameterCurrency: "JPY",
     AnalyticsParameterValue: 10000,
     AnalyticsParameterShipping: 500,
     AnalyticsParameterTransactionID: "192803301",
   ])

   Objective-C

   [FIRAnalytics logEventWithName:kFIREventEcommercePurchase
                       parameters:@{
     kFIRParameterCoupon: @"SummerPromo",
     kFIRParameterCurrency: @"JPY",
     kFIRParameterValue: @10000,
     kFIRParameterShipping: @500,
     kFIRParameterTransactionID: @"192803301",
   }];

To learn more about logging custom events in your app, visit the Analytics documentation.

Use other Firebase products in your app

After you add the Firebase SDK for Google Analytics, you can also start using other Firebase products, like Firebase Remote Config, Firebase A/B Testing, and Firebase Predictions.

• Remote Config enables you to change the behavior and appearance of your app without publishing an app update, at no cost, for unlimited daily active users.

• A/B Testing gives you the power to test changes to your app’s UI, features, or engagement campaigns to learn if they make an impact on your key metrics (like revenue and retention) before rolling the changes out widely.

• Predictions applies machine learning to your analytics data to create dynamic user segments based on your users' predicted behavior. These predictions are available to use in other Firebase products.
