Traffic custom creatives

Custom creatives are based on code snippets that you add by cutting and pasting your code, or uploading a text file.

Add a custom creative

  1. Sign in to Google Ad Manager.
  2. Click Delivery and then Creatives  and then Add creatives.
  3. Search for the advertiser you want to add a creative to. A creative is associated with one advertiser.
  4. When you've found the advertiser, click Continue.
  5. Click Custom.
  6. Enter a name for the creative.
  7. Select whether to add a code snippet for standard ads, AMPHTML ads, or both. Learn more about AMPHTML ads
  8. Enter the code snippet of the creative. You can paste the snippet into the Code snippet box or choose Upload files to upload a text file of the code snippet.

    If you're creating AMPHTML ads:

    1. You can start with the template that appears or replace it with a fully formed, valid AMP document. Learn more.
    2. Click Validate after adding your code to verify it’s a proper AMPHTML ads document. All code and referenced resources must be SSL.
  9. Insert click, cachebusting, and file macros into the code snippet by positioning your cursor in the appropriate places in the snippet and clicking the button for the macros you want to insert. Learn more about macros
  10. (Optional) Enter a Click-through URL for your creative's landing page.
  11. Select the Target ad unit size where the creative should deliver.
  12. (Optional) Enter multiple Third-party impression tracking URLs Beta.
    These are the URLs of third-party tracking services. The trackers are pinged when the creative appears and can contain macros. These URLs are not supported for creatives with an actual size of "Out-of-page."
  13. Click Save.
If you've selected a creative for upload that doesn't match the ad unit size you specified, you'll receive an error message when you save. Select Allow creative size to differ from ad unit size to resize the ad unit. (For example, if you upload a 400x400 creative to a 300x250 ad unit, Ad Manager will accommodate the larger creative. Or, if you upload a 200x200 creative to the same ad unit, the creative would only occupy 200x200 pixels on your page.)

Which creative version will serve?

The code type you select, along with the type of page you’re serving ads to, will determine the version of the custom creative served.

If creative wrappers are eligible to serve in the ad slot, but no AMP wrappers are available, Ad Manager will serve a standard ad.  Learn more

Custom creative HTML code type Creative served
Only standard HTML Standard ad
Only AMPHTML AMPHTML ad
Both AMPHTML and standard HTML AMPHTML ad

When serving ads to all other environments:

Custom creative HTML code type Creative served
Only standard HTML Standard ad
Only AMPHTML None (this will change in a future release)
Both AMPHTML and standard HTML Standard ad

If a creative is only eligible to serve in an AMP environment, it is only considered for AMP traffic when running forecasts.
