If you have purchased managed SEO services from a professional marketer, you will have to grant access to your Google Business Profile listing. If you already have access to this, then it is an easy process.
Owners of Business Profiles can invite users to become owners and managers. Each person can have their own access and they don't share sign-in info.
Only owners can add or remove users.
Managers can remove themselves from a profile.
Google Groups can’t be added as managers or owners.
Add owners & managers
Go to your Business Profile. Learn how to find your profile.
Click Menu
Menu
Business Profile settings
At the top left, click Add
Enter a name or email address.
Under "Access," choose Owner or Manager.
Click Invite.
Tips:
Invitees will have the option to accept the invitation and immediately become users. When they accept your invitation, you’ll get a notification email. Users in the account can find the names and email addresses of the owners and managers.
You can find all active users and people who are invited to become users. To cancel pending invitations, click
in the row.
Understand new owner & manager limitations
The new owner or manager of a Business Profile must wait for 7 days before they can manage all the features. During this 7-day period, they get an error if they:
Delete or undelete a profile.
Remove other owners or managers from a profile.
Transfer primary ownership to themselves or a third user.
If the new owner or manager deletes their account within the first 7 days, they’re removed from the profile. If they change their mind, they must be added again.
Tip: If an existing owner or manager tries to transfer primary ownership of the profile to a new owner or manager still in their first 7 days, they get an error.
