An event hit in Google Analytics is used to track user interactions with website elements, like a button click. Event hits have several parameters that can be included for reporting purposes, including:
* Category - The name you give to the group of objects you want to track. For example, if you're tracking form submissions, you might call the category Form Submissions.
* Action - A description of the event itself. For example, Clicked Submit Button.
* Label - An optional parameter used to specify additional information about the event. For example, you might use a label to indicate which form was submitted.
* Value - An optional numerical value associated with the event. Values can be used for things like indicating how much money was spent on a purchase.
