Online advertisers depend on tracking data to target their advertisements and marketing campaigns. This tracking data is mostly made up of cookies, browsing history, location information, and other details that are often shared without users knowing.

Much like there is a Do Not Call registry for telemarketers, internet users can request websites to withhold data from marketers, advertisers, and other prying eyes.

Do Not Track

Do Not Track is a privacy preference available in most web browsers, including Chrome, Safari, Firefox, and Edge.

This setting is an HTTP header field presented by a web browser to websites. The DNT header communicates to servers that a user reflects one of three value commands:

Value 1: The user does not want to be tracked (opt-out).Value 2: The user consents to being tracked (opt-in).Null Value: The user has not set the tracking option.

There is currently no law mandating advertisers to abide by users' Do Not Track preferences. However, sites may choose to honor the preference based on the value set in this field. You can research which sites honor Do Not Track by reviewing their privacy policies.
