here is what you need. Create segments in AA and then import to your Ads account.
Hope to help you
Thank you for reply.
creating a segment then download and import is manually work. Can we do directly using AA or launch.
In link they have given a way using audience Manager, but we don't have AMO.
I know this post is a year old but our company Datajoin can do this for you without the need for Audience Manager.
Check out my LI post on how to do the initial requirements (less than 10 mins if you have access to Google Ads and the remarketing tag).
Once that's in place you can start syncing segments manually, or better yet, skip all that hassle and use our 'Micro Integration' to automate that! Let me know if any questions and hope this helps!
