Google Ads Help: How to set up remarketing list sharing

In Google Ads, you can continuously share your data segments between manager accounts and their linked sub accounts. Create a single manager account to link different Google Ads accounts for different locations and share audience segments. Continuous sharing lets you auto share newly added segments directly from your manager account. As new accounts are linked to the manager account, they'll get these segments. Go into your manager account and click on admin, then manager account settings. Click the drop-down to set continuous audience sharing. Select the checkbox next to add this manager as an audience manager for all sub accounts. This ensures that all audience segments from your manager account will be shared with sub accounts. You can also check the box beside access and share all audience segments from specific sub accounts to select which specific sub accounts will share segments with your manager account and other linked sub accounts. Click the pencil icon to open the select accounts menu and select sub accounts that will share segments with your manager account. Click done, then save. To enable segment sharing from individual accounts, make the manager account the owner account within each individual account. To do this, sign into an individual account, click admin, and then access and security. Click on the managers tab and make that manager account the owner by selecting yes in the owner column. Keep in mind, it'll take up to 4 hours for new lists to appear in linked accounts and for shared lists to appear in manager accounts. For more information, visit the Google Ads Help Center.
