The ability to connect subproperties and roll-up properties to Search Ads 360 and Display & Video 360 has been implemented. Linking works the same way as it does for regular properties. Once linked, Google Analytics will deliver the same data as for regular properties.
With this feature, companies may now use Search Ads 360 or Display & Video 360 to advertise to subsets or supersets of their audience.
