How do you put age controls on Facebook?

[Lurch]

If I do not want someone of an age group to see my Facebook likes, posts, pictures, albums, profile, or friends. How do I set that up?

Example: If I posted mature content and did not want someone under the age of 18 years to see it.
Example2:If I was under 18 years and did not want some pervert looking at my page, anyone not in my friends list or over the age of 18 years to see any of my content.

How to I control the content I post to limit it from someone else viewing it?

Go to your Page. Click Admin Panel > Edit Page > Edit Settings > Manage Permission. You'll find an option there leveled Age Restrictions. Select your needed age from the select box. Thats it!

Selecting an age restriction means that anyone under the specified age will not be able to find your Page in search or on friends' profiles or view the content in other ways. This also means that logged out users will not be able to see your Page.

Facebook allows you to control which portions of your profile are visible to the public, your friends and even particular lists of friends. Hiding your birth year keeps your age private while still allowing people to send you birthday wishes. If your birthday is not visible on your profile, you can make it appear by toggling your account settings.
