How to Find Your Likes on Facebook – See Liked Posts, Videos, and Photos on Facebook
If you’re an avid Facebook user, you probably like dozens of posts a day from your profile on the site. By liking a post, you’re essentially letting the author of that post know that you’re giving credit to their work. In the background, you’re also creating a list of selected items that you like on Facebook. What if we showed you a way to see all of your Facebook likes?
There is indeed a way to see all the posts you’ve ever liked on Facebook. The site has something called Activity Log, which records all of your activity on the site. One of the sections in the log is for all of your likes and comments, and if you open it up, you should be able to find all of your likes across the Facebook platform.
The activity log is accessible from both the web and mobile versions of Facebook, so you can see all of your Facebook likes no matter what device you're using.
