Event Tracking
Quick Definition
Event tracking is the process of recording specific user interactions on a website such as clicks, form submissions, video plays, and scroll depth. In GA4, every data point is tracked as an event, making it the foundation of modern web analytics.
Why It Matters
Event tracking records specific user interactions beyond pageviews, such as button clicks, form submissions, video plays, and file downloads. In GA4, everything is an event. Without event tracking, you only know which pages users visited, not what they did on those pages.
Real-World Example
An Indian e-commerce site tracks these events: add_to_cart, begin_checkout, purchase, video_play on product pages, and scroll_depth on blog posts. This data reveals that users who watch product videos are 3x more likely to purchase, justifying investment in video content.
Signal Connection
Momentum -- event tracking reveals micro-conversions that indicate growing momentum. Increasing event counts for add_to_cart or newsletter_signup show the funnel is strengthening even before revenue increases.
Pro Tip
Set up at least these 5 events on every site: scroll depth (25%, 50%, 75%, 100%), outbound link clicks, CTA button clicks, form submissions, and file downloads. These cover the most important user interactions for any website.
Common Mistake
Tracking too many events without a clear purpose. Every tracked event should answer a business question. If you cannot explain why you are tracking an event or how you will act on the data, do not track it.

Show Answer
Answer: B. Events reveal what users do on your pages beyond just visiting them
Event tracking records specific user interactions (clicks, scrolls, downloads) that pageview data alone cannot capture. This reveals whether organic traffic is engaging with your content and converting.
