The Native Carousel offers advertisers the ability to tell a visual story by grouping up to five cards (images and captions) in a single execution. Each image that users swipe though can link to a unique landing page to drive deeper user engagement.
Carousel Ads can drive 2X to 3X higher CTR compared to single image ads.
Follow these steps to create Carousel Ads:
- Create a Campaign with the objective set to VISIT_WEB or PROMOTE_BRAND.
- Create an Ad Group with a CPC or CPM bid for Native.
- Create an Ad object with an Assets array: - In your asset array ensure the type is set to MULTI_IMAGE. - Include your basic and HQ image in ImageURL and ImageUrlHQ. - Set the order of your images in the Index parameter.
You are required to have a minimum of 3 cards per asset that can only be GIF, JPG or PNG formats with a maximum file size of 2MB. Your basic images must be 627x627 with a 1:1 ratio and your HQ images must be 1200x627 with a 1.91:1 ratio.
- Set all levels to Active. If the ad passes approval, it will be eligible to serve within 24-48 hours.
