Do Not Track or DNT is a web browser feature that lets websites know you don’t want to be tracked. When you enable the DNT setting in your web browser, it sends a Do Not Track request with your browsing traffic to all the websites you visit and the third-party services they’re using, asking them not to collect data about you and your browsing habits. This guide explains how DNT works and shows how to start sending Do Not Track requests in Google Chrome, Mozilla Firefox, Microsoft Edge, and Opera:

What is a Do Not Track request?

A Do Not Track request is a signal sent by your browser to the websites you visit, telling them that you don’t want their cookies and asking to disable user tracking. While you can enable DNT on any browser to send this request, there is no standard for how web companies, websites, and web services interpret and use DNT. If the websites you visit are set to respect your browser’s Do Not Track setting, ad networks should refrain from tracking you for advertising purposes and stop personalizing the ads they display in your web browser. Furthermore, websites should limit the information they collect about your browsing activity on their pages.

When our website receives Do Not Track requests from our visitors’ browsers, it collects less information about that visit. Another significant change is that we do not record the keywords you used in Google Search to reach one of our guides. In a nutshell, when DNT is turned on, we know less about how you reach and use our website.

If you’re not sure about your browser’s current Do Not Track setting, visit All About DNT to determine whether or not you’re being tracked.

Why do you want to send Do Not Track requests?

While enabling DNT may help make your browsing history a bit more private, that does not mean that all websites, ad networks, and third-party services stop tracking you. Some of them ignore your DNT setting and track you just the same.
