There are currently more than 2 billion active Facebook users. The platform is a great way to stay in touch with friends and family, especially considering it’s free to use. The fact that virtually everyone has an account, however, means it can be difficult to make sure that the status updates, photos, and messages you share stay only within a limited audience of friends. While Facebook has some very powerful privacy features, these are not all enabled by default. For instance, when you create a new account, your public profile is automatically visible to search engines such as Google. This can include information such as your name, birthday, and home town.
