With all the recent changes on Facebook you may have lost some of your privacy setting locations. This video shows you where to set who can see your personal information on your Info Tab and who can see which fan pages you like, and more.
In a nut shell, you will want to first go up to the small triangle on the top right of your Facebook and click Privacy Settings. Click on EDIT next to each area in there and double check all of your settings. Read these carefully and make your decisions as to whether you want the sections listed set to be viewed by the Public, by Friends, by Only Me (you!) or Custom, which allows you to make things visible to certain people or Friend Lists, or to hide them from certain people or Friend Lists.
But THEN what you will want to do is control who can see what personal information on your personal Profile Info tab. To do this go to your personal profile, click on Edit Profile at the top, and then look for the tiny icon next to each setting on each of the panels within your profile editor. Each one will be set to either Public, Friends, or something else depending on what your settings have been in the past, or whether you still have the default Facbeook settings.
Carefully go through each section as shown in the video and decide who you would like to be able to view which items. In general it is a good idea to keep anything business-related set to PUBLIC, if you want non-friends to be able to learn about your business.
