What does the Google Analytics: GA4 Event tag do?

• A. It deletes user data after 30 days
• B. It enables custom events to be sent to the Google Analytics 4 property, allowing tracking of specific interactions beyond automatic events
• C. It configures the GA4 property for data retention
• D. It only tracks pageviews automatically

Answer: (B)

GA4 uses events as the way you collect user interactions, and while many actions are tracked automatically, you often need to capture things that aren’t part of those defaults. The Event tag is what you use to send a custom event to your GA4 property whenever a specific interaction happens—like a button click, a form submission, or watching a video. You can name the event and attach parameters (such as category, label, value) to provide rich context about the interaction. This lets you measure actions that matter to your business beyond what automatic events cover. It’s not about deleting data, nor about setting data retention, and it doesn’t limit tracking to pageviews—it's how you bring in additional, custom measurements.
