There is an easy to replicate existing campaigns via AdNabu. This is usually required when you want to target a new location and want separate campaigns for it. To do so go to the campaign dashboard and scroll down to the campaign group table. Click on the copy button after selecting the relevant campaign group from the campaign dashboard.
You will have to enter a few details for the new group for eg: the budget and locations.
In the final step you will be prompted to select the campaigns you want to replicate. Please note, you will have to provide new names for the campaigns.
