Protected Audience API

In early 2020, Google first announced its intention to retire third-party cookies from Chrome. Despite numerous twists and turns, one thing remains certain: the relevance of third-party cookies is on a downward trend across most browsers, and this will likely affect Chrome as well. This development has marketers worried about the future of personalized and relevant advertising. The good news is they don’t need to be concerned. RTB House has managed to fine-tune Chrome’s new cookieless tool—the Privacy Sandbox—so that it can tailor ads to specific users while protecting their privacy. How is this possible, and what role does the Product-Level Turtledove play in the process? Let’s dive into it.

Despite their seemingly innocent name, cookies have found themselves at the heart of one of the internet’s biggest privacy revolutions. Specifically, third-party cookies have come under fire from privacy-advocacy groups, ultimately leading Google to work towards a cookieless future. This change will have significant implications for advertisers, as third-party cookies have been an essential targeting technology since their inception.

Let’s dive into the implications of Google’s decision and how you can prepare for the cookieless future.

In this Media Review, you can read about Privacy Sandbox’s General Availability, rebranding of First-Party Sets and enlarging its scale, further obstacles in the way of tracking individual users across the Internet, and regulatory updates in Europe.

We have previously presented what users will see in a cookieless future, what products will be displayed, and the end results—the visible consequences of the proposed changes to third-party cookies.

In this article, we would like to focus on what is happening behind the scenes.

Cookies play an essential role in the modern internet. These small pieces of data stored in your web browser can do everything from saving login details to enhancing website performance to helping marketers show users products that they will love. However, not all cookies are made equal, and there are significant differences between first-party and third-party cookies.

It might have been delayed, but the end of third-party tracking cookies is coming at the beginning of 2025, and businesses can’t afford to keep pretending otherwise. The good news is that thanks to this delay, there is still a small window of opportunity for companies to prepare for the cookieless future by engaging with the Google Chrome Privacy Sandbox.
