The Third-Party Cookie Is Dead (Sort Of) — What New York Marketers Need to Do Next

Few topics in digital marketing have generated more confusion over the past four years than third-party cookies. Google was going to kill them. Then they weren't. Then sort of. Most business owners tuned out somewhere around the third delay announcement and went back to running their campaigns the same way they always had. Here's the problem with tuning out: the resolution is not "everything is fine, nothing changed." Safari has blocked third-party cookies since 2020. Firefox since 2022. Add ad blockers and cookie consent declines, and roughly 30 to 40% of your audience is already invisible to your cross-site tracking — right now, regardless of what Google did. This post explains what actually happened, what it means for your campaigns, and exactly what to do about it.
