If your campaign is scheduled to start delivering immediately, we can't quote an exact time for your ad to be up and running, but it's usually within a couple hours of hitting "Launch."
Things that may cause a delay:
- Creating new lookalike audiences. Facebook takes time to "populate" large audience where they find the correct people to put in your target audience. To fully populate a lookalike audience can take up to 48 hours.
- Facebook's ad approval process. Facebook’s ad review time can be anywhere from 5 minutes to 2 days. Once your ad is created, it enters a review queue where a team of highly-trained Facebook employees will review it and then either approve or reject it.
If you'd like your campaign to begin delivering at an exact time, we recommend your create and launch with a start date that is in the future. This will "schedule" your campaign and give Facebook time to populate your audience and approve your ad.
If you ad campaign has had ads pending Facebook review for over 24 hours, please request a review directly from Facebook in order to quicken the resolution process. If your ads have been pending Facebook review for over 48 hours, please notify us on the 'Get Help' chat or at email@example.com.
