Google reversed course on killing third-party cookies, but tracking got noticeably less reliable anyway. First-party data is the only durable strategy left.
For years the industry braced for the death of the third-party cookie. It did not happen the way anyone predicted, and the real lesson is easy to miss.
Google reversed its plan to phase out third-party cookies and kept them under a "user choice" model. Its privacy-sandbox replacement effort effectively collapsed after regulatory testing reportedly showed roughly 85% attribution inaccuracy. So cookies remain, but their reliability has quietly declined, leaving measurement messier than before.
The panic was misplaced, but the drift is real: targeting and measurement got fuzzier. The durable answer is to own your data, your list, your purchase history, your consented site behavior, instead of renting tracking that keeps getting less accurate. Build the asset you control.
How WebKing runs this
We build your first-party data asset, the email list, the purchase history, the consented site behavior, and wire clean measurement on top, so your marketing decisions rest on data you own, not signals that keep degrading.
Google reversed its plan to kill them, so third-party cookies are still here. But their reliability has quietly declined, so you can't count on them the way you used to.
Google's privacy-sandbox replacement effort collapsed after testing showed roughly 85% attribution inaccuracy. It simply didn't work reliably enough to replace the old system.
No. Even though cookies stayed, tracking and measurement got noticeably fuzzier, so your targeting is less precise than before. Relying on rented tracking is becoming a weaker bet.
Own your own data instead: build and control your customer list, purchase history, and consented site behavior. This is the only durable strategy because it's yours to keep and improve, not dependent on unreliable third-party tracking.
