Third party cookies, the technology that powers retargeting and tracking, are disappearing fast. Safari and Firefox already block them. Chrome, which still holds most of the market, is phasing them out too.

That means traditional retargeting and attribution methods are becoming unreliable. Many brands are already seeing dropped ROAS, inconsistent reporting and lost conversions.

So why are top brands not worried?

Because they have already shifted to privacy first tracking and targeting methods, such as:

• First party data collection, building direct relationships via email, app logins and subscription touchpoints.
• Server side tracking and Conversion APIs, stronger tracking that works even when pixels fail.
• Universal ID solutions like UID2.0, RampID or login based identity frameworks, helping identify users without violating privacy rules.

Instead of waiting for cookies to disappear completely, these brands rebuilt their measurement and targeting systems ahead of time, and are now outperforming competitors who are still stuck.

If your campaigns are still dependent on old tracking methods, performance will drop significantly over the next few months. You do not need to panic, you just need a migration plan.
