Do Not Track is a browser setting that asks websites not to sell your data, but most websites ignore the request

Do Not Track is a setting you can turn on in your web browser that sends a message to every website you visit asking them not to track your online behavior or sell your information to data brokers. The problem is that turning it on does almost nothing. Websites are not required by law to honor the request, and most major sites ignore it entirely. It exists as an option, but it functions more like a polite suggestion than a working privacy tool.

If you are trying to stop data brokers from collecting information about you, Do Not Track will not accomplish that goal on its own. Data brokers gather information from public records, purchase histories, and websites that do honor tracking requests — but most sites straightforward disregard Do Not Track signals. You will need to use other methods, like the data removal process you came from, to actually reduce what brokers can collect.

Key Takeaways

  • Do Not Track is a browser setting that sends a request to websites, but websites are not legally required to follow it and most do not.
  • Turning on Do Not Track will not stop data brokers from collecting your information because brokers gather data from many sources beyond websites.
  • Do Not Track does not block cookies, ads, or fingerprinting — it only asks sites not to track you, which they usually ignore anyway.
  • If you want to reduce what data brokers have, you need to submit removal requests directly to the brokers themselves, not rely on Do Not Track.
  • Combining Do Not Track with other privacy tools like ad blockers and cookie managers provides more protection than Do Not Track alone, though it still will not stop data brokers.

How Do Not Track actually works (and why it fails)

When you turn on Do Not Track in your browser, it adds a small piece of information called a header to every request your browser sends to a website. That header says "DNT: 1" — essentially telling the site "please do not track me." The website receives this message and then decides what to do with it. Most major websites, including Google, Facebook, Amazon, and Twitter, have publicly stated they do not honor Do Not Track requests. They continue tracking anyway.

The reason Do Not Track fails is straightforward: there is no law forcing websites to listen. The Federal Trade Commission proposed Do Not Track as a voluntary standard in 2012, but it never became a legal requirement. Without legal teeth, websites have no reason to stop tracking you when tracking is how they make money. Advertisers pay for information about what you do online, so websites ignore the request and keep collecting data.

Even websites that claim to honor Do Not Track often do not do so completely. They may stop some forms of tracking while continuing others. Some sites honor it only for certain types of tracking while still collecting data for their own internal purposes. The lack of a clear legal definition of what "honoring Do Not Track" actually means has left the standard toothless.

What Do Not Track does not do

Do Not Track does not block cookies, which are small files websites store on your computer to track your behavior. It does not stop advertisers from building a profile of your interests. It does not prevent websites from using fingerprinting, a technique that identifies you based on your browser settings and device information rather than cookies. It does not hide your IP address or encrypt your internet traffic. It does not stop data brokers from buying information about you from other sources.

Many people turn on Do Not Track thinking it will make them invisible online or prevent targeted ads. It will not. You will still see ads, and they may still be targeted based on your browsing history. Websites will still know you visited them. The only thing Do Not Track does is send a request — and that request is almost always ignored.

Where to find and turn on Do Not Track

Do Not Track is built into most modern browsers. In Chrome, go to Settings, then Privacy and Security, then Cookies and Other Site Data, and look for "Send a 'Do Not Track' request with your browsing traffic." In Firefox, go to Settings, then Privacy and Security, scroll to Tracking Protection, and check "Always" under Enhanced Tracking Protection. In Safari on Mac, go to Safari menu, then Preferences, then Privacy, and check "Ask websites not to track me." In Edge, go to Settings, then Privacy, Search, and Services, and toggle on "Tracking Prevention."

Turning it on takes less than a minute, and it costs nothing. The downside is that it does almost nothing. Some websites may load slightly faster if they stop running certain tracking scripts, but you will not notice a meaningful difference in your privacy or the ads you see. If privacy is your goal, Do Not Track should be one small part of a larger strategy, not your main tool.

Better alternatives to Do Not Track for stopping data brokers

If your goal is to reduce what data brokers know about you, Do Not Track will not help. Data brokers collect information from public records, court documents, property records, voter registration, purchase history, and hundreds of websites — most of which ignore Do Not Track anyway. To actually reduce what brokers have, you need to submit removal requests directly to the brokers themselves. This is the process you came from: finding brokers that hold your data and asking them to delete it.

For protecting your privacy while browsing, better tools exist. A cookie manager like uBlock Origin or Privacy Badger actively blocks tracking cookies instead of just asking sites to stop. A VPN (virtual private network) hides your IP address from websites and your internet service provider. Private browsing mode in your browser deletes cookies and browsing history when you close the window. These tools actually do something, unlike Do Not Track.

The most effective approach combines several methods: turn on Do Not Track if you want, but also use an ad blocker, enable your browser's built-in tracking protection, clear your cookies regularly, and most importantly, submit removal requests to data brokers directly. No single tool will make you completely invisible, but layering multiple protections is more effective than relying on any one of them.

Why browsers still offer Do Not Track if it does not work

Browsers keep Do Not Track as an option because it costs them nothing to include and some users want it. It is also a way for browsers to appear privacy-conscious without actually limiting their own tracking or their partners' ability to track users. Firefox and Safari market themselves as more privacy-focused than Chrome, and offering Do Not Track is part of that marketing, even though the setting is largely ineffective.

Some privacy advocates argue that Do Not Track should have been made into a legal requirement, similar to how the European Union's GDPR law requires websites to ask for permission before tracking. In the United States, no such law exists, so Do Not Track remains a voluntary request that most websites ignore. The setting persists as a reminder of what privacy protection could look like if it were legally enforced, but it is not.

Frequently Asked Questions

Does turning on Do Not Track stop websites from seeing what I do?

No. Do Not Track only sends a request asking websites not to track you. Websites are not required to honor it, and most do not. Websites will still see that you visited them, what pages you looked at, and what you clicked on. Do Not Track does not hide your activity — it just politely asks sites to ignore what they see.

Will Do Not Track stop data brokers from collecting my information?

No. Data brokers collect information from many sources, including public records, court documents, and purchase history — not just from websites. Even if every website honored Do Not Track, brokers would still have access to most of the information they sell. To reduce what brokers have, you need to submit removal requests directly to them.

Is Do Not Track better than nothing?

Turning it on is harmless and takes one minute, so there is no reason not to do it. But do not expect it to meaningfully improve your privacy. It is better to spend that minute setting up an ad blocker or enabling your browser's built-in tracking protection, both of which actually block some tracking instead of just asking sites to stop.

What is the difference between Do Not Track and private browsing mode?

Do Not Track sends a request to websites asking them not to track you. Private browsing mode deletes your cookies and browsing history when you close the window, so websites cannot use stored information to recognize you on future visits. Private browsing actually does something; Do Not Track does not.

Can I use Do Not Track instead of submitting removal requests to data brokers?

No. Do Not Track only affects websites you visit going forward, and most websites ignore it anyway. Data brokers already have information about you from past activity and other sources. To remove that existing information, you must contact brokers directly and request deletion. Do Not Track will not erase data they already hold.
