Google Analytics 4 (GA4) – Technical Interview Questions & Answers

Google Analytics 4 (GA4) is revolutionizing how we track and analyze user behavior across websites and apps. Preparing for a GA4 technical interview requires a deep understanding of its event-based model, custom events, and cross-domain tracking. Here are key GA4 interview questions to help you ace your next interview.

Google Analytics 4 (GA4) – Technical Interview Questions and Answers

1. What is the difference between GA4 and Universal Analytics in terms of data collection?
   • Answer: GA4 uses an event-driven data model, allowing for more flexible and detailed tracking of user interactions. Universal Analytics relies on a session-based model, which aggregates user interactions within a session.
2. How do you implement GA4 on a website?
   • Answer: Implement GA4 by creating a new GA4 property in Google Analytics, generating a measurement ID, and adding the GA4 tracking code to your website’s header. Alternatively, use Google Tag Manager to deploy the GA4 configuration tag.
3. What are the key components of an event in GA4?
   • Answer: Key components include the event name, parameters (such as page_location, event_category, and event_action), and optional user properties. These elements provide detailed information about user interactions.
4. How do you track custom events in GA4 using Google Tag Manager?
   • Answer: In Google Tag Manager, create a new tag of type “GA4 Event,” configure the event parameters (name, value, etc.), and set a trigger to specify when the event should fire. Ensure the GA4 configuration tag is also set up correctly.
5. Explain the role of parameters in GA4 events.
   • Answer: Parameters provide additional context and details about the event, such as item names, categories, or user actions. They allow for more granular data analysis and reporting in GA4.
6. What are Enhanced Measurement events in GA4, and how do they simplify implementation?
   • Answer: Enhanced Measurement events are automatically tracked events like page views, scrolls, outbound clicks, site search, and file downloads. They simplify implementation by reducing the need for custom tagging.
7. How do you set up cross-domain tracking in GA4?
   • Answer: Set up cross-domain tracking by adding the domains to the “List of domains” under the GA4 property settings. Ensure that the GA4 tracking code is implemented correctly across all domains and that linker parameters are enabled.
8. What is the GA4 DebugView, and how do you use it?
   • Answer: DebugView is a feature in GA4 that allows you to see real-time data as events are triggered on your site or app. Use it by enabling debug mode in your implementation and accessing the DebugView report in the GA4 interface.
9. How do you create custom dimensions and metrics in GA4?
   • Answer: Create custom dimensions and metrics by navigating to the “Custom Definitions” section in the GA4 property settings. Define the name, scope (event or user), and parameters to track the desired custom data.
10. How does GA4 handle user privacy and consent management?
    • Answer: GA4 includes built-in features for data anonymization, user consent management, and data retention controls. It allows businesses to comply with privacy regulations like GDPR and CCPA.
11. What are predictive metrics in GA4, and how do they benefit businesses?
    • Answer: Predictive metrics use machine learning to forecast user behavior, such as purchase probability or churn probability. They help businesses identify high-value users and optimize marketing strategies.
12. Explain the concept of “data streams” in GA4.
    • Answer: Data streams represent the sources of data (web, iOS, Android) that flow into a GA4 property. Each stream collects user interactions and events, allowing for comprehensive cross-platform analysis.
13. How do you migrate goals from Universal Analytics to GA4?
    • Answer: Migrate goals by recreating them as conversion events in GA4. Identify the key interactions you tracked as goals in Universal Analytics and configure them as custom events in GA4, then mark them as conversions.
14. What is the Analysis Hub in GA4, and how do you use it?
    • Answer: The Analysis Hub is a feature that allows users to create custom reports and visualizations. Use it by selecting a template (e.g., exploration, funnel analysis), adding dimensions and metrics, and applying filters to analyze data.
15. How do you use GA4 to track e-commerce activity?
    • Answer: Track e-commerce activity by implementing GA4’s recommended e-commerce events, such as “view_item,” “add_to_cart,” “purchase,” etc. Use Google Tag Manager or directly embed event code in your site to capture these interactions.
