Think of cookies like Batman’s Bat Tracer. When you visit a website, Batman sticks a cookie on your browser to follow you around. Batman can then go back to his Bat Cave and watch where you’re going and where you’ve been. A little Big Brother-ish to be sure, but cookies also provide direct benefits to surfers, including remembering passwords and bringing you offers in which you are genuinely interested (see Behavioral Targeting). This tracking helps to reinforce the data provided by Google Analytics and similar analytics platforms.
