Google has officially kicked off its ambitious plan to bid farewell to third-party cookies, marking a big move in online privacy. Starting January 4, 2024, the tech giant is initiating a phased approach, disabling third-party cookies for 1% of global users initially. This move aims to test the waters before a gradual expansion, encompassing 100% of users by the third quarter of 2024.

Introduction of Tracking Protection

Google unveiled Tracking Protection, a novel feature set to redefine cross-site tracking limitations. This innovative addition, forming part of its Privacy Sandbox initiative, takes a significant stride towards discontinuing the use of third-party cookies.

Randomly selected participants, Google users will experience Tracking Protection upon opening Chrome on desktop or Android devices. This feature will restrict third-party cookies by default during web browsing, curtailing the tracking of user data across diverse websites. Instead, Chrome will locally organise users’ interests on their devices, keeping these categories inaccessible to websites.

Third-party cookies have long been utilised by advertisers to track users across different websites, constructing comprehensive profiles of online behaviour. This practice raises considerable privacy concerns, as users may not fully comprehend the extent to which their online activities are monitored and shared.
