Question: Tierra is the marketer for Far West Imports. She's the project lead for a new smartphone app that will help customers order products more easily. Thanks to Google's advice, their dev team has incorporated many features to boost conversion numbers. The marketing VP is insisting that you assess the efficiency of the shopping cart and checkout features. Which Google service allows them to test the app's UI and features?
- Google Analytics 360
- SplitMetrics
- Optimizely
- Firebase A/B Testing
Explanation
A/B Testing is used to run controlled experiments on app experiences and measure which variant improves target outcomes. It can test UI and feature changes through Firebase Remote Config without requiring every variation to be hard-coded into a new release. This makes it appropriate for evaluating shopping cart and checkout changes inside a mobile app. The results help identify which version reduces friction and improves conversion behavior.
Why the other options are incorrect
SplitMetrics is not the Google service used for Firebase-based app UI and feature experiments.
Optimizely is a third-party experimentation platform, not the Google service specified for app testing.
Web Vitals measures web experience signals, not app UI experiment variants.
Optimize 360 was for website experimentation, not Firebase-based app feature testing.
Google Analytics 360 measures and reports behavior, but it is not the app UI testing service.
