It is very easy to delete your Facebook ad. You may be running so many ads that now you want to delete an old ad., or maybe you've created an ad incorrectly or perhaps it is no longer required so you want to delete it?
The steps below describe how to delete your Facebook ad:
Step 1: Go to Ads Manager
Step 2: Click on 'All Ads' to display all your ads
Step 3: At right of the ad that you want to delete, in the 'Status' column, click on ad status icon, and then click 'Deleted'. Once you click 'Deleted' your ad will be deleted.
This was how to delete a Facebook ad. Remember ad once deleted can not be recovered, so before deletion make sure you really want to delete it.
