The ad target template is the mechanism by which to pass dynamic data into ad creatives. It can be assigned to different objects:
Assigned To | Applies to | Purpose |
Ad | Specific ad | Pass individual ad data |
Adgroup | Ads in adgroup | Used by campaign bundles to provide macros from creative data sets |
Store | Ads in adgroup with store assigned | Used by campaign bundles to provide store data to the creative |
If multiple levels are assigned, the ad target template data is merged.
