Privacy-First Responses

As cookies weaken, several techniques help you keep measuring while respecting consent. They all share a theme: rely on first-party data you are allowed to collect.

The main moves

• Consent Mode plus modeling, to recover conversions lost to denial.
• Enhanced Conversions, sending hashed first-party data (such as an email) to improve match rates.
• Server-side tagging, moving collection to your own server for first-party context and more control.
• Conversions API, server-to-server events for platforms like Meta.

These are covered in their own right in the offline conversions and server-side material; here the point is that they exist as deliberate answers to the privacy shift.
