Sure, I can simplify it a bit. To track how many clicks each menu items receive, you would first need to log custom events with Firebase. Now these custom events can be of two types – recommended and custom. Google suggests that you should implement the recommended ones as these can better enrich your data in the GA4 user interface.
The custom events give you more flexibility. You can decide your own naming convention for event names and their parameters. Just remember to keep your naming structure consistent and create a simple documentation to track this.
For tracking menu clicks, my suggestion would be to create a custom event named “navigation_click”. Now, this event will need more details about what specifically was clicked right? That’s where parameters like “name” come into play. You can fill in the name of the menu item that got clicked as the value for this parameter.
Finally, remember to register this parameter in GA4 property so that these events can get tracked. Check out Google’s official documentation if you need step-by-step instructions.
