Carousel Ads¶

The Yahoo 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
Thumbnail - 180x180px	Optional	Optional	No - 1:1
Account logo - Height: 180px min, Width: 180px - 2560px	Optional	Optional	No - 10.1 maximum
Account icon - Height: 180px min, Width: 180px - 2560px	Optional	Optional	No - 1:1

For Portrait Moments native ads, we recommend using 720p to 1080p high resolution images. The dimensions for this vertical image is 1080px by 1920px (9:16 aspect ratio). The min dimension should be 720px by 1280px

For Panorama Moments native ads, the image must be 2276px by 1280px or wider (max of 6826px by 1280px) high resolution image. The mage aspect ratio must be between 16:9 and 48:9.
