1: Choosing an individual wall post's or photo's privacy settingsWhile posting your photo or post, click on the down arrow left to the post button. Select Custom from the drop-down menu. Using the pop-up, select who you wish to make a post visible to. You can select if you wish to show a post to friends, friends of friends or specific people or a specific list of people.
|Select Custom Privacy Options|
2: Limiting the Audience for an entire albumThis is much similar to setting the audience for an individual picture. Just go to your albums, click on the Settings icon on the bottom right of the album whose privacy settings you wish to customize. Then select Custom from the drop down menu. The options Facebook offers are almost the same as those for an individual photo, however there is one difference.
All those people who are tagged and their friends would still be able to see the photos in your album. To prevent this, you will have to change the privacy settings of each individual photo.
3: Making all your Photos and Posts PrivateThis is the permanent solution against worrying about your Facebook content. However, it doesn't offer much customization options and should only be used if you are sure how you will use Facebook. This is a 2 step process and involves customizing the audience for your past posts as well as those you will make in future.
Step 1: Limiting Past Posts & Photos
Go to your Privacy Settings, and then go to "Limit the audience for posts you've shared with friends of friends or Public?." Then click on the "Limit Old Posts" button. In the pop-up, click Confirm. This is a permanent change and cannot be undone. However, all those tagged and their friends would still be able to see your posts. To prevent this, you will have to change each post's settings individually.
Step 2: Limiting Future Posts and Photos
While in the privacy center, click on "Who can see your future posts?" This will open a non-functional status update box. However, the privacy options that open when clicking on the down arrow right next to the post button are functional and act as global defaults for the content you post on Facebook in the future. Make sure to select friends if you only wish to share content with your friends. You can however, change this according to your needs; but for most people, friends would be the best option. You can further improve your privacy by selecting Custom and then unchecking the check box that appears next to "Friends of those tagged". This will customize your Facebook settings to show your Facebook activity only to your friends and those tagged.
You can also select who gets tagged in your content to further prevent your content from appearing in front of unwanted eyes. To do this, go to your Privacy Settings from the Settings icon located at the top right of the blue Facebook bar. Then, in Privacy Settings, click on Timeline and Tagging. Then under, "How can I manage tags people add and tagging suggestions?", select Enabled to review tags that friends add to your posts.
Facebook's privacy settings take some time to adjust but once you are done, you will never have to worry about your content ending up in front of unwanted users.
