Seller-defined Audiences

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.

This article aims to complete the round of quality tests performed on the sampled Seller-Defined Audiences signals we received from the sell side. While the previous article investigated contextual SDAs, this one will focus on user SDAs and verify how they reflect reality. The tests in this section varied from the ones performed on the contextual signals as the nature of the user type differs. The first test relied on a manual check of an assignment mechanism, while the second one was based on a survey campaign.

2023 has been a year of big changes for marketers. Artificial Intelligence tools like ChatGPT have transformed how many of us do our jobs, third-party cookies are on the cusp of being retired, and consumers have become more privacy-conscious than ever before. Despite the enormity of these changes, in many ways they’ve just set the scene for the big things to come in 2024. To understand what’s going on, we’ll briefly review MarTech trends in 2023, and then dive into the top MarTech trends in 2024.
