Event deduplication ensures that the same event is not counted multiple times when using both client-side and server-side tracking. For example:
A user clicks a button, and both the browser (client-side) and server log the event.
The server assigns a unique event ID to each tracked action.
Analytics platforms, like Google Analytics 4 or Meta Ads, use this event ID to identify duplicates and only count the event once.
Deduplication is crucial for maintaining accurate data when multiple tracking methods are used.
