What is a Google My Business Listing?
A Google My Business (GMB) listing is a profile of your business that appears in Google Maps. The top three listings will also commonly appear in standard search results for location-based searches. This is referred to as a "map pack".
How to Share Access to Your Listing
If you work with an agency or freelancer that helps with your SEO and/or PPC it's likely they'll ask you to share access to your Google My Business listing. This will allow them to review the listing for optimisation opportunities and link the listing with a Google Ads account to enhance your local advertising.
Sharing access is simple:
Login to your Google My Business profile.
Click Users from the left side navigation.
Click the blue Add users button from the pop-up that appears.
Enter the email address you've been asked to share access with.
Choose Owner or Manager for the user role. In most cases, the Manager user role will be sufficient.
Click the blue Invite button and you're all done!
Owner vs. Manager User Role Permissions
The only difference between the Owner and Manager user role in Google My Business is that managers cannot remove the business listing and cannot manage users.
Managers can edit and configure all other options within the Google My Business listing. The only real reason to give a user Owner permissions is if you want to allow them to add or manage additional users directly.
