This may include creating and editing campaigns, reviewing performance, managing conversion settings, and completing other campaign-management work. The advertiser’s original users continue to access the account using their existing sign-in information. Billing and payment methods also remain in place unless the advertiser separately authorizes a billing change or consolidated billing arrangement. A manager account does not receive administrative ownership of an existing client account by default. Administrative ownership is a separate setting and should only be granted when there is a specific reason to do so.
