If you are a geek or a bit serious about online privacy, you must be familiar with the term “Do Not Track”, a new kind of privacy term used my modern browsers and websites. As per I guess, most people spotted the term first when installing Windows 8, where it asks the user whether to keep enabled or disable Do Not Track on Internet Explorer, though Mozilla was in the first place to implement Do Not Track in Firefox.

Discourage tracking

What is “Do Not Track”

“Do Not Track” (DNT in short) is a user changeable preference in web browsers that users can set to tell websites and web applications that the he or she “don’t want to be tracked”. This enables users opt out of tracking by websites they visit using the browser. Tracking is done in various ways including tracking of user behaviour, web analytics to gather user information, tracking user data to target relevant ads depending on user’s interest, etc.

From social networks to advertising firms, all are involved in tracking in one way or another who are using or visiting their service.

Pros of “Do Not Track”

If a website or web service respects your DNT preference, it will not track your activity, interest and behaviour. This should improve your online privacy and give you extra confidence while browsing online. Your information are not gathered this way.

Cons of “Do Not Track”

  • This is an important fact of DNT. Turning on Do Not Track on your web browser simply means you are telling websites that they should not track you. This is a kind of request. That means it will not block any website from tracking you, nor prevent them. It’s up to a web service or website if they should obey your request or not. So you can’t rely on this preference on your browser.
  • Another downside of turning on Do Not Track is, if a website or ad service serves personalized service or content this is based on tracking, you could end up getting irrelevant content if they do not track you. Also, Do not Track is not similar to private browsing.

How DNT works

If you tuned on DNT on your browser, the browser will add an HTTP header (specific to DNT) to every request you make to load a webpage. Thus the websites can read your DNT request. The method is universal.

Today’s all modern browsers come with DNT preference. DNT is turned on by default on Internet Explorer unless you choose to disable it while upgrading windows. On other browsers, you need to turn it on manually. Here are visual guides on how you can enable DNT on popular browsers. Before proceeding, make sure you have the latest version of the browser.

Do Not Track is a request that you tell web sites that you are not a fan of being tracked via your browser. Web applications, ads and tracking services decide whether to track you or not. It’s not that serious that it sounds.
