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?

Analysis of Correct Answer(s)

• Firebase A/B Testing is the correct answer because it is a Google service specifically designed for running experiments within mobile and web applications. It allows marketers and developers to test different variations of an app's UI, features, or messaging to see which version performs better in terms of key metrics, such as conversion rates. In this scenario, Tierra can use it to create and test different versions of the shopping cart and checkout flow to identify the most efficient design.

Analysis of Incorrect Options

• Web Vitals: This is a Google initiative focused on measuring and improving the user experience on the web, not within native mobile apps. Its core metrics (LCP, FID, CLS) assess page loading performance, interactivity, and visual stability, which are not the primary tools for A/B testing specific in-app features like a checkout process.

• SplitMetrics: This is a third-party service, not a Google product. The question specifically asks for a Google service. While SplitMetrics also offers A/B testing, its primary focus is often on optimizing app store listings (icons, screenshots, etc.) rather than in-app functionality. The duplicate listing is a common distractor in exam questions.
