Summary

As specified in the creative submission guidelines for Display Ads, animated image creatives are not supported. To align the submission specifications with this policy, we have added a restriction that prevents the submission of image files in APNG format.
As a result of this change, image files in APNG format can no longer be submitted on or after the implementation date.

Notes

  • Ads that already use submitted APNG format images will continue to be delivered. These images will be displayed in ads as static images.
  • For Dynamic Display Ads, products configured with APNG format images cannot have review-related items updated on or after the implementation date. Delete the products that use APNG format images and re-register them using images that comply with the creative submission guidelines.

Comments

Please use video ad formats as an alternative to animated image creatives.
