Facebook wants to know as much about you as possible and tracks the things that you like. One reason it does this is to provide targeted ads. But do you ever wonder how much information Facebook actually tracks about you? Now, you can find out.
A Google Chrome extension called What Facebook Thinks You Like can help you see the types of data Facebook is collecting.
What Facebook Thinks You Like collects the types of categories Facebook has grouped you in, which can give you a pretty good idea of what types of ads you'll see on your page.
If you like certain bands, books, and TV shows, for example, Facebook could pick up on that based on your activity. The Chrome extension itself does not collect things like cookies from your posts.
