GA4 Event
In Google Analytics 4, an event is the core unit of measurement. Every interaction, from a page view to a click, form submission, or purchase, is recorded as an event with optional parameters that add context. GA4 replaced the older session-and-pageview model of Universal Analytics with this event-based structure.
Why It Matters
Because GA4 is built entirely on events, how you name and structure them determines what you can report on and mark as a conversion. Clean, consistent event design is the foundation for measuring lead generation and campaign performance.
Common Mistake
Firing generic events without descriptive parameters, or creating inconsistent event names across pages. This produces reports that cannot be segmented meaningfully and makes key conversions impossible to isolate later.
