Ad previews are an advanced view of your ads running within ad campaigns. Previews can be produced for supported ad types on active Facebook, Google, and Bing ads.
You can see the ad previews in Marketing 360® by navigating to the Ads app:
Facebook Ad Previews are produced using a direct link from the connected Facebook ad account. Previews are based on information and settings applied to the ad via ads managers or business managers.
Some facebook ads may require additional permissions for the preview to work. Social Targeting or Retargeting ads require both an ad account and the correlating Facebook Business page to be connected to Marketing 360® (see articles for Connecting Ad Accounts and Connecting Social Accounts).
Google ad previews must be reconstructed in-platform using relative ad criteria. Each ad type will typically have its own list of ad criteria used to build the ad. Currently Text, Call, and Image ads are supported in the Ad Previews feature. Dynamic ads, responsive search ads or ads using dynamic add-ons are not able to be supported.
Much like Google Ads, Bing Ads use sets of ad criteria for the construction of ads. Text, Image, and Call-only ads are supported. Dynamic Ads are not supported for the Ad Previews feature at this time.
