Cookies Aren't Dead. They Just Evolved.


Listen Later

Todd and Kelly break down the practical difference between zero-party data (what people willingly tell you) and first-party data (what you observe from owned interactions), and why the industry’s privacy shift has not eliminated tracking so much as it has made measurement more fragmented and harder to interpret.

They debate whether cookies will ever truly go away, why consumer behavior tends to default to convenience (even when privacy is a concern), and how “sleeping giants” with money and incentives will keep finding new ways to build audiences.

From there, they explore where synthetic personas fit in today: not as a magic replacement for real data, but as a way to pressure-test messaging, creative, and experiences before spending heavily.

Finally, they zoom out on the bigger measurement challenge: when direct attribution gets noisy, the next frontier is faster, more accessible pattern recognition and media mix-style modeling powered by AI, which can help marketers ask better questions, explore more hypotheses, and make more confident decisions across long, multi-touch journeys.
