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.
I’ve been using Facebook for long but I did not know that it will not be searchable even on Facebook? I thought just Google?
It hides on both sites according to my research.
