2. Overview of GA4 Events

  • 2-1. Definition of Events in GA4

  • An event in Google Analytics 4 (GA4) is defined as an action that a user takes on a website or app, ranging from clicking a link to completing a purchase. Events provide a mechanism for measuring specific interactions or occurrences. For instance, an event allows tracking actions such as page loads, clicks on links, or form submissions, as well as system behaviors like app crashes. In GA4, events replace the concept of 'hits' used in Universal Analytics, enabling a broader collection of data regarding user interactions.

  • 2-2. Importance of Event Tracking

  • Tracking events is essential for understanding user interactions and optimizing business performance. Without event tracking, businesses lack insights into whether they are facilitating meaningful interactions on their platforms. Events allow for precise measurement of user behavior, helping to analyze aspects such as button clicks, scroll depth, downloads, and form submissions. By tracking events, businesses can derive actionable insights that inform content improvements, marketing strategies, and overall site usability.

3. Types of Events in GA4

  • 3-1. Automatically Collected Events

  • Automatically collected events in Google Analytics 4 (GA4) are user interactions that are tracked by default without the need for additional code or tagging. These events are captured once GA4 is set up on a website or an app using the Google gtag or Tag Manager snippet. Key examples of automatically collected events include: 'first_visit', which occurs when a user visits a site for the first time; 'first_open', which is triggered the first time a user launches an app after installation; 'file_download', which is initiated when a user downloads a file; 'session_start', indicating user engagement with the app or website; 'page_view', reflecting each page load; and 'ad_click', which triggers upon clicking an advertisement.

  • 3-2. Enhanced Measurement Events

  • Enhanced measurement events are an automatic feature of GA4 that can be activated within the settings without requiring any additional coding. To enable these events, one must navigate to the Admin settings and adjust data stream options under the property settings. The enhanced measurement captures various user interactions, such as 'scroll', which tracks when a user scrolls through 90% of a page; 'click', which signals when a user clicks outbound links; 'view_search_results', which indicates instance of site searches based on URL parameters; 'video_start' and 'video_complete', tracking the engagement with embedded videos that support JavaScript API.

  • 3-3. Recommended Events

  • Recommended events in GA4 are specific actions that Google suggests default to optimize user engagement tracking. Implementing these requires manual setup using predefined names and parameters. Some examples include 'add_to_cart', triggered when a user adds a product to their shopping cart; 'add_payment_info', when payment details are entered; 'add_to_wishlist', for items added to user wishlists; 'level_start', indicating a new level in a game; and 'tutorial_complete', which marks the completion of tutorials.

  • 3-4. Custom Events

  • Custom events in GA4 are user-defined interactions that do not have default tracking set up. Businesses can tailor these events to track specific behaviors unique to their requirements, such as form submissions or specific button clicks. Before creating custom events, it is advisable to review the list of automatically collected, enhanced measurement, and recommended events to avoid overlap. Custom events can be created and defined through Google Tag Manager or directly within the GA4 interface.

4. Event Implementation and Tracking

  • 4-1. Setting Up Events in GA4

  • Setting up events in Google Analytics 4 (GA4) allows users to track important actions taken by users on websites or apps. Events such as page views, clicks, and form submissions can be tracked to gain insights into user engagement. GA4 has moved away from the rigid event tracking structure of Universal Analytics, offering more flexibility. You can create custom events according to your specific tracking needs, while GA4 automatically collects basic event data, including first visits and session starts, as well as several automatically collected events like user engagement being tracked when a webpage is in focus.

  • 4-2. Using Google Tag Manager for Event Tracking

  • Google Tag Manager (GTM) provides a user-friendly interface for managing event tracking in GA4. With GTM, users can implement both automatically collected and custom events with ease. Users can create new events directly through GTM's dashboard by defining relevant triggers and variables. For instance, a new event can be set up to track the visits to a thank-you page after a form submission. This is done by selecting the relevant page view and configuring the associated parameters accurately in GTM. GTM facilitates the tracking of more complicated events without needing deep technical skills.

  • 4-3. Creating Custom Events

  • Custom events in GA4 allow for deeper customization apart from the automatically collected and recommended events. Users can create up to 500 defined custom events tailored to their specific interactions. These custom events require manual implementation and do not appear in standard reports unless custom reporting is set up. For example, a custom event might track the completion of a demo booking by naming the event meaningfully and establishing matching conditions to ensure accurate tracking. Once set up, it may take up to 24 hours for the new event to be visible in GA4's interface.

5. Analyzing Event Data

  • 5-1. Understanding Event Counts

  • Event count in Google Analytics 4 (GA4) refers to the total number of times an event has occurred, providing insights into the frequency of user actions on a website. This metric is essential for understanding how often specific actions, such as clicks, downloads, or video plays, take place. By analyzing event counts, users can identify trends, measure the effectiveness of their marketing strategies, and prioritize content creation efforts based on user engagement. The focus on event frequency shifts the analysis towards user interactions rather than mere page views, enhancing the understanding of user behavior.

  • 5-2. Utilizing GA4 Events Report

  • The GA4 Events Report offers a comprehensive view of user interactions, serving as a critical tool for effective tracking and analysis of user behavior. Unlike Universal Analytics, which focused on sessions and pageviews, GA4 emphasizes events and user engagement, providing a deeper understanding of how users interact with a website or app. Users can access the Events Report through the GA4 interface by navigating to 'Reports > Engagement > Events'. By employing various filters and breakdowns, users can analyze event data to uncover patterns and insights aligned with their business objectives. The utilization of the GA4 Events Report allows businesses to make data-driven decisions, tailoring their content, products, and marketing strategies to meet user needs.

  • 5-3. Key Events and Their Significance

  • GA4 categorizes events into multiple types, each catering to distinct tracking needs. The main types include: 1. **Automatically Collected Events** - These events are tracked by default without any setup and include examples like 'session_start' and 'first_visit'. 2. **Enhanced Measurement Events** - These track interactions automatically but can also be customized, covering actions such as 'page_view' and 'scroll'. 3. **Recommended Events** - These require user setup and are proposed for specific scenarios, including 'add_to_cart' and 'purchase'. 4. **Custom Events** - These are uniquely customizable to track specific interactions vital to a business. The significance of these events lies in their ability to provide insights into user behavior, enabling businesses to identify popular features, understand user engagement, and ultimately optimize the user experience on their platforms.

6. Practical Applications of Event Tracking
