Find out who viewed your profile on Facebook. This is a question that many people are asking and they did not find an actual solution. It is the most common question and people are wondering how do I know who visited my Facebook account. The answer to this question is not a secret formula but it depends on your Facebook account and how you want to know who visited it. The most common way is to install an application that will let you know who visited your profile. But there are two problems with this method. The first problem is that some applications are not reliable and they might not work as they should. The second problem is that the application will consume a lot of your battery and you will need to uninstall it to use it.
