You can duplicate an ad set in two ways, by using import ad set or duplicate ad set feature.
- Duplicate ad set is useful when you want to copy over all attributes of an ad set including the associated ad creative
- Import ad set is useful when you want to be selective about ad set attributes you want to copy, and do not want to copy over ad creative.
To duplicate an ad set select the ad set(s) you want to duplicate in ads manager, and click the 'Duplicate Ad Set' button.
Next, choose where you'd like to duplicate your ad set into, you have the option of duplicating to the current campaign or a different campaign. You can duplicate into any existing campaign.
Once you click 'Duplicate 2 ad sets' you will be redirected to the destination campaign you've copied your ad sets into. Some settings may change when you duplicate an ad set, learn more here.
