What kind of data does the GA4 Event tag send to the GA4 property?

• A. Only pageview data
• B. Custom events representing specific interactions
• C. Server error logs
• D. User demographic data

Answer: (C)

In GA4, the data sent by an Event tag is event data that captures user interactions. When something happens on your site or app—like a button click, form submission, video play, or a search—the Event tag fires and sends an event to the GA4 property. Each event includes a name and parameters that describe the interaction, allowing you to analyze how users engage with your site.

While page views are themselves events, the typical purpose of the Event tag is to record specific interactions you care about, usually as custom events tailored to your needs. It isn’t about server logs by default, and demographic data isn’t what the Event tag transmits by itself.
