In this edition of the Cookieless Newsroom, we highlight Microsoft’s deployment of the Ad Selection API in its Edge browser, a tool similar to Privacy Sandbox's Protected Audience API. We also cover a recent academic study demonstrating the suitability of the Protected Audience API for retargeting. Additionally, we report on a landmark European regulatory fine imposed on Google’s MarTech division.

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.

The cookieless future is fast approaching. This decision by Google, sparked by very real privacy concerns, removes a key personalization capability for advertisers: third-party cookies. To counteract this, Google has been building a series of tools to replicate their functionality, and today we’re going to dive into one of them: Google Topics API.

Google is coming for your cookies, and not the tasty kind lying safely in a tin in your kitchen, but the third-party ones that sit in your browser, watching, waiting, and storing all kinds of information. This has major implications, some good and some bad, for marketers and consumers alike. It also means that many of our old tools will soon become obsolete. However, you don’t need to crack open your tin of real cookies and start stress-eating yet. There are plenty of new tools on their way, one of which we’re going to get into today: The Protected Audience API.
