As the third-party cookie apocalypse approaches, it’s looking increasingly likely that there will not be one sole replacement that will satisfy publishers’ and advertisers’ needs. That’s never more evident than when you ask a media company about the different data collection strategies they’re testing right now.

At Hearst UK, Faye Turner, head of commercial strategy and insight, and Ryan Buckley, head of digital, are leading the charge of finding and testing various methods of data collection. On the latest episode of the Digiday Podcast, they share how over the past few years, they’ve tested and implemented different alternatives to third-party cookies ranging from 50,000-person audience panels to newer options like clean rooms and data matching.

But with any new tech, possible downfalls and red herrings are bound to reveal themselves in what Buckley calls the “gold rush” of third-party cookie alternatives, including clean rooms.
