Here you will find step by step instructions on how to add an ‘Admin’ to your facebook business page
Step 1: Log in to your personal facebook account.
Step 2: Navigate to your business page by doing a quick search for your business on the search bar. You will know if you are the existing admin of your page if your page looks a little different than most business pages. It will say ‘Admin Panel” on the top of the page.
Step 3: Click on the ‘Edit Page’ button on the top right. Then click on ‘Admin Roles’.
Step 4: You will now see all Admins for your business page listed here. It may currently only show yourself as the admin. Click the ‘Add Another Admin’ link. Enter the e-mail address of the user you would like to add.
Step 5: Select the ‘Role’ you would like to allow this user to have. For access to all items on your Business Page select ‘Manager’. Then hit ‘Save’.
You will see the new admin’s profile has been added to your admin area. This new admin will receive a notification email letting them know they have been assigned an admin of your page.
To Remove an Admin: - Hit the ‘X’ next to the users name in the Admin Area. This will instantly take away their admin privileges.
