What are GA4 events and how do I use them?

ROI answers

GA4 events are user interactions with your website or app that you define as significant – think button clicks, form submissions, video views, or even a user spending a certain amount of time on a page. As of early 2026, these events are the fundamental building blocks of data collection in Google Analytics 4, replacing the session-based model of Universal Analytics.

  • Enhanced Measurement: Current systems include automatically collected events like page views, scrolls, outbound clicks, site search, video engagement, and file downloads – requiring minimal setup.
  • Custom Events: You can define and track specific actions relevant to your business goals, such as product adds to cart or newsletter sign-ups.
  • Recommended Events: GA4 now features a library of pre-defined event names and parameters for common e-commerce and app interactions, ensuring data consistency and better reporting.
  • User Properties: You can attach custom data about your users (like location, customer type, or membership level) to events for more granular analysis.

In 2026, Australian businesses need to be particularly mindful of data privacy regulations like the Privacy Act. GA4’s consent mode, which adjusts data collection based on user cookie consent, is crucial for compliance. Properly configured events allow you to accurately measure the effectiveness of your digital marketing spend, demonstrating ROI to stakeholders and informing future strategies – especially important given the competitive landscape for Australian SMEs.
