You must make sure that all internet users can see your facebook business page, even users that are not logged in to facebook. If the settings on your page are wrong, you will block everybody.
Here’s how to let everyone see your facebook business page, even when they are not logged into facebook:
1. “Click” Edit page
2. “Click” Manage Permissions
3. Change the Age restrictions to anyone (13+)
4. Save Changes
Watch out it might be possible that some of your facebook likes will be deleted.
