Before you post, look at the audience selector. Use the dropdown menu to choose who you want to share a post with.
Public
Friends (+ friends of anyone tagged)
Only Me
Custom (Includes specific groups, friend lists or people you’ve specified to include or exclude)
You'll see this tool wherever you share content, whether it’s a status update or information on your profile (timeline).
The tool remembers the audience you shared with the last time you
posted something and uses the same audience when you share again unless
you change it. For example, if you choose Public for a post, your next
post will also be Public unless you change this audience when you post.
If you want to change who you’re sharing with, open the dropdown menu
and choose a different audience. Remember: anyone you tag in a post,
along with their friends, may see the post.
To make it clear
who you’re sharing with at all times, the audience you select appears
along with whatever you are saying, every time you share. You can also
use the audience selector to change who you are sharing with after you
post something.
Note: You will not be able to use the
audience selector unless you are posting on your own profile (timeline).
If you post to another person's profile (timeline), the person whose
profile (timeline) you are posting to controls what audience can view
your post.
