I'm working on trying to migrate an old set of deprecated Google Ads connectors to the new versions. However, these original ones utilized the also deprecated Google Doubleclick cookie share service to build audiences for users who do not enter our CRM or provide us contact details otherwise. I've been trying to discern what, if anything, is replacing this same functionality but the information is a struggle to find, even when I have direct communication with Google engineers. It's possible Google Signals will work, but none of that is mentioned in any of the documentation for the Tealium connector or Google's documentation, the closest is the mobile-centric MOBILE_ADVERTISING_ID, but that does me no good for the half of users that are desktop.
I guess what I'm really trying to get to the bottom of is, has in fact the ability to use Tealium (or any 3rd party CDP) to build and manage audiences in Google Ads that have NOT provided an email or phone to hash just no longer an option. It seems like I am forced to manage audiences for any non-converted users over on their respective platforms (GA4 for Google) and only my nurturing audiences can be managed in Tealium now. Anyone else have any insight so I can understand if I just need to give up this quest and start to design out my non-converted audience strategy outside of Tealium?
