While setting up your promotional campaign, you can choose how long you’d like the promotion to last. However, this is not a guarantee and it may take longer than your selected end date.  

Why did my campaign exceed my end date?

Your selected end date is a guide, not a guarantee.  While our system will attempt to match your end date, it can exceed it when the campaign is not generating enough views.  The pacing of your campaign primarily depends on the size of your targeted audience.  You can reach more about slow campaign delivery (and how to speed it up) here.

When will my campaign end?

Your promotion only ends when your budget reaches $0.00.  It does not end when your selected end date is exceeded.
