You have spoken and we have listened and implemented the changes into the Zemanta dashboard so you can easily expand the reach of your campaigns.
As a Zemanta marketer, you are now able to expand the campaign media source easily from native to display reach. There is a tick box within the Publishers & placements targeting in the ad group settings which says Have your native ads served within display placements. The box is preselected so that by default you are also running on display inventory in addition to traditional native placements. Below and next to the checkbox, we offer a brief explanation of what it means when this box is selected. The tick box will only be shown when you select Native campaign type. The checkbox is visible in both new ad group creation and existing ad groups.
For more clarity and additional information on display inventory for native campaigns, please check this Help page.
If you do not want your ad groups to run on any display placements, or if you have any questions, please reach out to your account manager.
