In Google Analytics 4, what is primarily used to track user interaction on a website?

In Google Analytics 4, events are primarily used to track user interactions on a website. This represents a fundamental shift from previous versions of Google Analytics, where pageviews and sessions were the primary metrics for measuring user behavior.

In GA4, the focus on events allows for a more granular and detailed understanding of user interactions. Each user action – such as clicks, form submissions, video plays, and downloads – is tracked as an event. This model allows for capturing a wide variety of engagements beyond just traditional pageviews, offering insights into how users are navigating and interacting with a site.

As a result, the event-driven approach enables businesses to better analyze user behavior, assess the performance of specific features, and optimize interactions based on actual data. This flexibility and depth of tracking are what make events the cornerstone of user interaction analysis in GA4.
