Carousel Ads¶

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.

Example¶

How-To¶

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.

Note

You are required to have a minimum of 3 cards per asset that can only be JPG or PNG formats with a maximum file size of 2MB.

Set all levels to Active. If the ad passes approval, it will be eligible to serve within 24-48 hours.

Important: New Restrictions for Square Image (imageLargeUrl)¶

When creating your ad, you will need to include an imageUrl and imageUrlHQ. Note that the imageLargeUrl must have a 1:1 aspect ratio. A square image (imageLargeUrl) is mandatory. If you upload an 800x1000 image, for example, the asset will be cropped to 800x800 pixels. Also ensure a 1:1 aspect ratio and exact size of 627x627 for a square asset for single image ads.

This applies to the API and to BULK. Ensure that you follow these requirements when creating single image and carousel ads. Use a 1:1 aspect ratio and an exact size of 627x627 for a square asset for carousel ads.

The image requirements for various assets is shown in the table below:

Asset	Native UI	Native API	Aspect ratio enforced?
Rectangle image - 1200x627px	Required	Required	Yes - 1.9.1
Square image - 627x627px	Required	Required	Yes - 1:1
