Event parameter
A parameter is an extra piece of information attached to an event, such as a product name, a price or a page category.

Parameters turn a simple event into something you can analyse. A “purchase” event on its own tells you little; with value, currency and items attached it tells you what was bought and for how much.
Tools limit how many parameters you can register and how many distinct values they can hold, so it pays to plan them deliberately.
