Dynamic HTML5 ads require both a feed file in Microsoft Excel spreadsheet (XLSX) format and the image assets referenced in the spreadsheet. Static HTML5 ads require only a single image asset per ad.

NOTE
You can use each feed file for only one catalog.

File requirements

  • Dynamic HTML5 ads:

    • A feed file in CSV, TSV, or Microsoft Excel spreadsheet (XLSX) format, with one header row and one data row for each ad variation. Include an image name in each row using the format images/image_name (such as images/300x250_acme_logo.png).

      The advertiser-specific field names must map to the available fields for dynamic ad feed files.

    • The associated image assets in GIF, JPEG, JPG, or PNG format. See the supported creative sizes.

    You can upload a single XLSX file, a single image file, or a single ZIP file containing any combination of XLSX and image files.

  • Static HTML5 ads:

    • One image asset per ad in GIF, JPG, JPEG, or PNG format.

      You can upload either a single image or multiple images in a ZIP file.

Upload an asset file

NOTE
Instead of uploading asset files, you can also directly upload a catalog when you add dynamic creatives to a creative library. Any catalogs you create there become available within the Catalogs view for future use.

  1. In the main menu, click Creative > Feeds.

  2. Click the Assets tab.

  3. In the upper right, click Create > Asset.

  4. Configure the asset file:

    1. Select the advertiser who can access the asset file.

    2. Specify the asset file in either of the following ways:

      • Drag and drop a file on your device or network into the box.

      • Click Select a file to locate the file on your device or network.

All ZIP files are decompressed automatically. When you upload a spreadsheet file, the file is listed on the Feeds subtab. When you upload an image file, the image file is listed on the Images subtab.
