When you click “Like” on a Facebook page, it appears on your wall and in your Facebook news feed for your friends to see. If you want to view all of the pages you have liked on Facebook, a section of your profile displays them for later reference.

Click “Profile.” Click “Info” under your profile photo.
Scroll down to the “Activities and Interests” bar and click "Edit." Click "Show Other Pages" to list all of the sites that you have “Liked” on Facebook.
