The short history matters here. Google announced third-party cookie deprecation for Chrome, delayed it repeatedly, and then in 2025 reversed the plan entirely, choosing to keep third-party cookies rather than remove them, and subsequently scaling back the Privacy Sandbox initiative that was meant to provide alternatives. The practical status today is that third-party cookies still function in Chrome.

It's tempting to read that as 'tracking is fine again', but that conclusion doesn't survive contact with the rest of the market. Safari has blocked third-party cookies for years through Intelligent Tracking Prevention, Firefox blocks them by default, and Brave and Edge add their own restrictions. Chrome keeping the cookie changes nothing for the large share of your traffic arriving on those browsers, where conventional cross-site tracking already fails.

The lesson is to stop treating any single browser policy as the deciding factor. The trend across the industry runs one direction, toward less reliable client-side measurement, even when an individual vendor pauses. Whether or not Chrome ever revisits deprecation, the resilient approach for a WooCommerce store is to own a first-party dataset and collect events server-side from your own origin, so your measurement no longer hinges on a single vendor's cookie decision buried in someone else's release notes.
