How do I know what link my friend "liked"?

[Lucy Star]

I got a message saying one of my friends "liked" my link. I don't remember posting any links per se...how can I check this out? Does a link show up as pages that I have "liked"? Thank you.
Of course I clicked on the notification; it did NOT direct me to the post.
