In order to protect your privacy settings, you must understand what exactly you are looking to change so you don’t block out your friends and rather block out search engines!
The first step into changing Facebook privacy settings is to go into the privacy settings tab after you sign in.? On the top right hand corner, click on the drop down menu from Account until you see the privacy tab.
In the privacy settings, make sure you click on customize and choose which settings you wish to have for each group- whether that information be open to everyone, friends of friends, friends alone or “other.”? I have all of my settings on Friends so an unapproved guest could not start viewing my pictures and contact information.
Below that giant main screen, there is an applications settings link.? Click on it to turn off the changes to internet search engines.
