To edit an ad campaign, you will go select “Retargeting” or “Search” and select “Program.” Click on the ad campaign you want to make edits to and click “Edit.”
Your ad will be paused until the new edits are approved by Facebook or Google. Start date, end date, and ad budget cannot be edited once your ad is launched. If you would like to modify the dates or budget of your ad, you must cancel your ad and create a new one.
