You have the option to mark sponsored content accordingly in the radiosphere Studio Editor. This way you can show your users at a glance that the content you publish is commercial. Sponsored posts are marked with a label on the header image. This notice will also be displayed on the teasers.
Mark post as sponsored
To mark a post as sponsored, open the overview of the post. Now click on Setup your post here... click on the gray Ad Settings field.
In the next step, activate the Mark as Ad checkbox and optionally enter the name of your advertising partner in the empty Advertiser Name field that appears. Click Save and Close to confirm your entries. Important: The Advertiser Name is for internal purposes only and will not be displayed on the ad label on the header image.
After you mark the post as sponsored, an ad label will appear on the header image in the post as well as on the post teaser.
