Hi,
Event Tracking in Google Analytics

Category
This is the generic name of the group of objects you want to track. In reference to the PDF download, the category title for this event can simply be "PDF Download."

Action
Actions are always paired to a specific category and can speak to a more specific type of user interaction. Using our annual report PDF example, the action title for this event could be "Annual Report."

Label
Attributing labels to events is optional, but recommended. Labels add another dimension with which to present the event data.
