Q: What exactly does turning on the “Do Not Track” in my browser actually do?
A: It’s no secret that we’re all being tracked relentlessly online, so the “Do Not Track” setting in your browser sounded promising. Flip a switch, and websites stop following you around the internet, right? Unfortunately, it doesn’t quite work that way.

What it was intended to do
When enabled, this feature adds a small message to every web request you make that says, in effect, “please don’t track me.” It’s like the speed limit signs we see every day. Whether others honor that sign is completely voluntary.
