Study first
Review the ideas behind the questions
These notes cover how events, parameters, key events, DebugView, and reports connect in a GA4 setup.
Events are the measurement base
GA4 measures interactions as events. Page views, clicks, purchases, and sign-ups can all be represented as events.
- Some events are collected automatically.
- Enhanced measurement can collect common web interactions.
- Recommended events use names and parameters Google defines for common actions.
- Custom events should be named clearly and consistently.
Parameters add detail
Event parameters provide extra information about what happened. They can describe values such as item names, link URLs, or search terms.
- Parameters make event data more useful in reports.
- Custom dimensions can expose selected parameters in reporting.
- Do not send sensitive personal information in event data.
- Consistent parameter names reduce reporting confusion.
Key events and testing
Important events can be marked as key events. DebugView helps confirm that events and parameters are arriving during setup.
- A key event marks an action important to the business.
- DebugView is useful during implementation testing.
- Realtime can help with quick checks.
- Events should be tested before they are used for decisions.
