How does Facebook come up suggested post?

[Green]

I was online searching products on the Home Depot website when i went to my Facebook i saw suggested post on my wall with the same products i was searching on the home depot website, this has happened before with other things as well. How does Facebook know what i am searching outside of there site especially since i haven't mentioned any of these products on my own face book?
