Third and first party cookies in Google Chrome – latest news

When it comes to the subject of third-party cookies withdrawal in Google Chrome, it’s worth keeping an eye on the ball. Ultimately, these cookies were crucial to online advertising, as they allowed tracking user activities, and in consequence, they were served with personalized ads. However, with the end of third-party cookies for all Chrome users seeming inevitable, it’s essential to keep up with the latest news. What do we know about an upcoming cookieless world in the second quarter of 2024?

  • As already announced in 2020, Google plans to withdraw all third-party cookies. Now, we know that it has been postponed again, and the third-party withdrawal in Chrome will probably take place at the beginning of 2025. The Privacy Sandbox initiative has the task of mitigating any negative consequences that may arise from this change. A deprecation of third-party cookies will become a reality only if all remaining problems reported by the British CMA (The Competition and Markets Authority) are resolved;
  • For now, we are in the first phase of experiments, where only 1% of browsers experienced third-party cookie phase-out;
  • Randomly chosen browsers face such cookie withdrawals. Any affected user will be notified.

What is Privacy Sandbox?

The aim of Privacy Sandbox, a solution developed by Google, is to facilitate the shift from the prevalent use of third-party cookies in Chrome to eventually eliminating them altogether. Additionally, the secondary goal is to minimize cross-site and cross-app tracking, as well as fingerprinting (because fingerprints – traces of the user, can be utilized for tracking users across sites). Designers of the solution want to safeguard users’ privacy but, at the same time, not hurt advertisers and, in consequence, publishers’ interests. No wonder, as many of them raised concerns about potential revenue drops due to the feared negative impact of the restriction and subsequent complete withdrawal of third-party cookies.

Privacy Sandbox can assist publishers in entering the cookieless world thanks to solutions, such as:

  • Differential privacy, which is a system that makes it possible to uncover behavior patterns without disclosing private information concerning individual users;
  • K-anonymity is a privacy concept that helps to measure anonymity within a dataset;
  • On-device processing, which enables the calculations on a user’s device (like on a tablet or mobile phone).

Playing the waiting game

Although Google is still testing how the cookieless world is going to look, it’s highly probable that third-party cookies will be withdrawn as soon as the beginning of 2025. Therefore, it is worth staying patient and keeping up with all the latest news from Google. We will keep you updated on all changes on our blog. Stay tuned!
