A great way to keep track of who sees what you post on Facebook is to put your friends into lists. Say for example you wanna post a funny, but dirty joke, but don't want your family to see. Putting your family into one list, called "Family," and then restricting them from the post. To edit your lists, click on Friends on the lower left side of the home screen. You will see pre-made lists like "Restricted" and "Acquaintances." You''ll also see lists based on any work place or school you included on your profile. You can add people to these lists or take them away. You can even create your own custom list based on your own criteria.
