If you'd like to limit the visibility of a Facebook post or photo to a specific audience, the social network integrates a built-in privacy tool to help you manage post visibility. Here is a quick tip on how to set the visibility of your Facebook posts.
How To Change the Privacy Level of a Facebook Post
To change the visibility of a publication, click on the Audience Selector button displayed at the top-right corner of the post. Click on More Options to select whom you would like to view the content:
Public: Everyone can see the publication.
Friends : Only your friends can see the post.
Only me: Only you can see the post.
Custom: Allows you to designate which users can see a post.
