The first step is to allow subscribers to your Facebook profile; to do so, follow these steps.
After setting, the early subscribers begin to appear. To see them, just go to the menu under your cover photo of the same title.
To control who subscribes to your profile and see what information can be seen on your profile, go to the arrow icon in the top right of Facebook menu and select 'Account Settings'.
Go now to the category 'Subscribers'; here your username and other settings that you can modify to your liking will appear.
To get the information you are looking for, click on "Want to know what are your subscribers? View your public life '.
If after doing this step, you find a publication that prefer to keep private or vice versa, just go to it and click on the icon next to the date to do so. If you choose public, you can see your subscribers.
