How ads follow you around the internet



Hint: It’s why every site asks you to accept cookies.


You’ve seen the pop-ups: “This site uses cookies to improve your experience. Please accept cookies.” Cookies do improve your experience. They function as the website’s short term memory; with each new click you make, cookies help the site identify you as the same person. Imagine every time you add something to your cart and click away, it disappears. Or each time you load a new page on Facebook, you have to log in again. Without cookies, the online world we know today couldn’t exist.
