Migrated LSA campaigns require the right Google Ads access level for whoever is managing them. In practice, an agency should have enough permission to view and edit the migrated campaign, manage budgets and settings, and review performance data.
For an agency takeover, it’s best to use the appropriate Google Ads manager or account access rather than sharing login credentials. The business should keep ownership of the account while giving the agency only the access it needs.
After migration, check that the agency can access the new campaign, make changes, view billing or budget information where required, and access the relevant reporting. The exact permission level can depend on how the migrated account is structured, so verify the access requirements in the account before making changes.
