3rd-party Cookies

Have you ever downloaded the data Facebook has on you? Or Google? The sheer breadth of data collection has 86% of consumers worried, and this has led to a number of users leaving data-hungry social media platforms. It has also forced organizations like Google to do some soul-searching and adjust their approach to user data, notably by retiring third-party cookies.

In 2023 Google announced the depreciation of third-party cookies and began the development of the Google Privacy Sandbox. However, the deadline has once again been pushed back, this time to 2025]. The reason? “The need for more time to evaluate and test the new technologies.” Despite positive developments, RTB House’s own tests of the FLEDGE proposal, with nearly 8 million ads in 50 countries, have shown that there is still plenty of work to be done to build effective cookieless alternatives.

As a new year dawns, many of us are looking toward 2023 with trepidation. A potent cocktail of skyrocketing inflation, a looming recession, and general global instability has created a difficult environment for companies in almost every industry. However, things aren’t as bad as they seem, and if companies can take advantage of the evolving MarTech trends, they can thrive despite the adversity.

The cookieless future is fast approaching, and this means that brands need to rebuild their marketing strategies around alternatives to third-party cookies. Navigating this new environment will require mastering a suite of tools, including another type of cookies: first-party cookies.

To understand how you can make the most of first-party cookies, let’s dive into what they are, how they work, and how advertisers use them.

On April 18th, Google published the results from Google Ads’ interest-based advertising testing, where, among other tools, Topics API was analyzed. We are happy that the Google Ads team joined RTB House and Criteo in openly publishing findings from experiments with Privacy Sandbox APIs.

In the report, the Google Ads team compares the effectiveness of applying Topics API, contextual signals, and publisher first-party IDs instead of cookies for Interest-Based Advertising (IBA). Third-party cookies were allowed in this experiment for use cases unrelated to targeting, such as frequency capping and measurement.
