Ever wonder how e-commerce websites like Amazon or eBay know it’s you coming back to shop again, emblazoning a big ol’ “Welcome Back” banner at the top of the page? Or how the GameStop website remembers what’s in your cart even when you navigate to another page? Or why that smart appliance you looked atonce is now following you around in every ad space imaginable?
What Are Cookies?
Cookies are how web servers figure out that it’s you returning to a website and not someone else. They build up a “profile” about you, which allows a site to customize and personalize your browsing experience. Think: product recommendations on Amazon or a clothing shop that shows a list of other trousers or sweaters you might like based on what you last clicked. Cookiebot—a site that can analyze cookie compliance for businesses—aptly refers to cookies as “the memory of the internet.”
