Ad Bulk Edit

The possibility to edit multiple ads simultaneously depends on what you want to change. The only change you can apply in bulk after publication is the targeting of your ads (which ad set they are assigned to).

You can do this inside your published campaign. If you go to Performance Insights and select the Creatives & related ads tab, you can check the box on the left side of the title of your ad and select Edit selection. Here the only possible option to choose is Add audiences.

All other changes are made per ad group; that is to say, individually.
