Amazon Ad Server will be sunset in Q4 2024, please visit this page (AAS offboarding information) for offboarding support resources and sunset FAQs. Details shared on that page represent the most up to date information in the Help Center, if you find disparate information in other resources please default to the information in the AAS offboarding information page accordingly.


If you used a third-party authoring tool, such as a code editor or Adobe Animate, to build your expandable banner, proceed to set up your ad in Amazon Ad Server (AAS) .


Note: If you used Ad Builder to build your expandable banner, this set up is not required and you can proceed to sharing your ad. For more information, see Share Your Ad.


Before uploading your ad to AAS, verify that you have completed these prerequisites:

  • The folder that contains your assets does not include unnecessary files. For example:

    • Unused assets such as images, videos, or fonts.

    • Work files such as .psd, .fla, or .scss.

    • Hidden files such as thumbs.db (Windows) or .DS_Store (Mac).

  • Create a workspace (zip file) for each ad. It is recommended that the zip file name matches the final name of the ad.

  • Each workspace contains its default image (named Default or Backup). This image should be optimized and lightweight.


Note: Naming the workspace and the default image are especially useful when using the Ad Creation Wizard to bulk upload your work; the Ad Name field and the Default field will be filled in automatically. For more information, see Set up multiple ads using Ad Creation Wizard.
