You can choose to run your ad continuously or set a fixed period of time for your campaign to run. If you choose to run your ad continuously, it will serve up to the daily budget amount you’ve designated every day until you manually turn it off.
If you choose a fixed period of time, you can customize the pacing of your campaign:
- Pace your budget evenly (you’ll spend about the same amount each day for the entire length of the campaign).
- Fulfill your budget as quickly as possible (you’ll win all the impressions for which you’re the highest bidder, and your entire budget may be spent before your end date).
