3rd-party Cookies

Have you heard of Seller-Defined Audiences (SDA) yet? SDA was released at the beginning of 2022 by Project Rearc – an initiative that came to life as the IAB Tech Lab’s answer to the impending demise of 3rd-party cookies. Although a year hasn’t passed since its release, SDA has received significant attention in the press and industry conferences and is considered one of the go-to solutions for targeting when the 3rd-party cookie pond dries up.

Google proposed that instead of deprecating third-party cookies for all users in Chrome, they will let users decide whether to allow third-party cookies in the browser. Google also emphasized their continued investment in the Privacy Sandbox to ensure its performance and utility.

The Privacy Sandbox timeline states that in Q3 2024, “Chrome will phase out support for third-party cookies over a two-month period.” Whether or not Q3 2024 is the right time is an important question, but in this blog post, we’d like to focus on the second aspect of the deprecation—the duration of the time over which it reaches 100% of users. We will argue that a two-month timeframe (a “cliff”) is too quick and therefore, dangerous. To maximize the chances of AdTech successfully transitioning to a cookieless world, the deprecation ramp-up should be more prolonged, gradual, and known in advance.

The digital world is a complex ecosystem designed to simplify access to information and help people connect easier with fewer limitations. While not paying for it directly, we need to remember that apart from being a content platform, the Internet is also an enormous marketplace, where we – as users – are clients.

Over the years, http cookies have become an integral part of the Internet and are the most popular method of identifying users for personalizing a message. Due to their prevalence, the distinction between the types of computer cookies was not well known for a long time – cookies were simply cookies.

The digital marketing landscape is a very complex environment. There are many players with different profiles of activities addressing the diverse needs of their clients.
