A sub-manager account is the owner of all the linked sub accounts. Hence all data segment sharing owned by the sub accounts can be managed by the sub-manager account that owns the linked sub accounts.

To set up continuous audience sharing in your manager account, follow these steps:

1. Sign in to your Search Ads 360 experience.
2. Navigate to a sub-manager account.
3. Click Settings in the page menu, then Manager account settings.
4. Click to expand the selection menu for “Continuous audience sharing”.
5. Check the box beside “Add this manager as an audience manager for all sub accounts”. This ensures that all segments shared with or owned by your manager account will be shared with its sub accounts.
6. Click Save.
