How to hide all information on facebook from non friends

Click the "Who can look up your profile by name or contact info?" drop-down menu and select "Friends of Friends" or "Friends" to limit the people who can view your Facebook profile. This hides your profile from being visible in public searches on Facebook or from search engines like Google.

Tap in the top right of Facebook, then tap your name. Scroll down to the post you want to edit. Tap in the top right of the post and select Change Audience. Select a new audience from the options that appear (example: Public, Friends, Only Me).
