Understanding the Fundamentals of GA4

Google Analytics 4

Google Analytics 4 (GA4), launched in October 2020, is the latest version of Google’s web analytics service. The platform offers detailed statistics about a website’s traffic, traffic sources, and measures conversions and sales. GA4 represents a major shift in how web analysis is done on the platform. It introduces a new, event-based data model to replace the session-based model of its predecessor, Universal Analytics.

What Is GA4 and Why Was It Developed

GA4 is a cutting-edge, analytics tool developed by Google that provides advanced tracking capabilities and enhanced reporting features. It’s designed primarily as a forward-thinking tool that’s more adaptable to modern internet usage. GA4 was developed to handle the ever-evolving, multi-platform internet usage such as desktop, mobile, apps, and progressive web applications. It provides insights for both app and web, as it’s an App + Web property.

The event-driven data model used in GA4 allows digital marketers and data analysis to track a more comprehensive set of user interactions. Every click, scroll, or user interaction is seen and recorded as an event. This approach gives a wider view of user behavior on a website or app.

Key Features of GA4
  • Machine learning-powered predictive metrics
  • Expanded codeless tracking
  • Audience definition and reporting
  • Cross-platform tracking and reporting
  • Integrated view of customer journeys
  • More granular user permissions
The GA4 Event-driven Data Model

In GA4, the event-driven data model is central to how web analytics operates. This model eschews the conventional session/interaction paradigm of Universal Analytics. Instead, everything that happens on a website or app is recounted as an event. This could range from page views, button clicks, user actions, or system events.

For example, if a user visits a website, each action they take (like clicking a button, filling out a form, or consuming content) will register as a separate event. This model allows for a much more detailed understanding of user behavior.

How GA4 Distinguishes Itself from Universal Analytics

GA4, previously known as Google Analytics 4, diverges from Universal Analytics in a significant way—the data model. While Universal Analytics is built upon a user-session-hit data model, GA4 employs an innovative event-driven model. This difference makes GA4 a highly adaptative tool. It affords the ability to track and analyze user behavior across multiple platforms such as the web, iOS, and Android under one comprehensive report.

Furthermore, GA4 boasts extensive privacy protection features which Universal Analytics lacks. It is equipped for a future both with and without the assistance of cookies.

Exploring the Event-Driven Data Model

Digging Deeper into GA4’s Event-Driven Data Model

In stark contrast to the traditional sessions-and-page-view model underlying Universal Analytics, GA4 instead uses a dynamic event-driven data model. This new approach is revolutionary in its ability to offer in-depth and actionable insights, all while keeping the user at the center of the data. With this event-driven model, businesses can grasp a clearer and more involved understanding of their website or application’s performance.

Understanding GA4 Events

A fundamental component of the GA4 event-driven data model is the ‘event’. In GA4, an event refers to the user interactions with a website or app that can be tracked independently. These could be button clicks, form submissions, or page views, among other user actions. Each event in GA4 is designed to provide insights about what a user does while interacting with your website or application.

Importantly, GA4 is designed to automatically collect a select number of essential events. These include first_visit, session_start, user_engagement, page_view, and more. The ability of GA4 to automatically collect these events eliminates the need to set up additional event tracking code for these basic, but still insightful, user actions.

Diving Deeper into Event Parameters

Each event in GA4 can also have ‘parameters’. Parameters are additional bits of information tied to an event that provide more specific details about it. For instance, if the event is “view_item”, parameters could involve details like item_id, item_name, or price. User properties, on the other hand, are attributes that persist beyond a single event and describe the state of a user, like ‘interests’ or ‘geographic location’. Through parameters and user properties, GA4 offers a more comprehensive insight into user behavior.

Comparing GA4 Event Model to Universal Analytics’ Data Model

Comparing GA4’s event-driven model with the Universal Analytics model demonstrates the evolution of Google’s analytical offerings. In Universal Analytics, the fundamental units of measurement were sessions and pageviews. Although these metrics are important, they often don’t provide a comprehensive view of how users interact with a website or app.

On the contrary, GA4’s event-driven model offers a more granular look into user interactions. By focusing on user actions, rather than the broad scope of sessions or page views, GA4 provides valuable insights that can directly inform strategy and pinpoint areas for development.

Understanding the Shift to GA4’s Event-Driven Data Model

Google Analytics 4 (GA4) offers an event-driven data model which is altering the perspective of digital analytics. With a new focus on user interactions, a vast amount of detailed data is readily available, providing a broader, yet precise, comprehension of user behavior. Though it might seem intimidating to shift away from the traditional session-and-page-view model, the enhanced insights derived from GA4’s event-driven model make it an invaluable asset in today’s digital analytics landscape. As the internet and user behavior persistently evolve, so should the analytical tools that help understand and optimize such interactions.

The process involves tracking automatic, recommended, and custom events, which will be explored in more depth subsequent to this discussion.

Understanding GA4 Event-Driven Data Model

GA4’s event-driven model changes how data is collected and understood. Rather than using a session-based model, user interactions, from simple activities like clicks to complex transactions, are treated as events. This allows for a robust view of user journeys and more data-driven improvements to user experience.

Setting up events in GA4

Setting up events can be completed through three categories: automatic, recommended, and custom events.

  • Automatic events are pre-defined by GA4 and can be accessed once properties are established. Examples include first_visit, page_view, and user_engagement.
  • Recommended events are configured and are customizable for industry types, such as e-commerce or gaming. These are vital in rendering data readable, especially for specific reporting needs. Examples include login, subscribe, and purchase.
  • Custom events are directly created by the user when they need to track something individual to a website/app. Examples include promo_hover.
Tracking Events in GA4

Tracking events is essential for data assessment. Tags are added to code to trigger and gather data from events. Automatic events are done through GA4, while recommended and custom events must be implemented through manually adding tags, custom event parameters, naming custom events, and coding elements on your website.

Reports Generated

Reports are created for tracked events that supply data-driven insights for website improvement and customer experience enhancement.
