1P Tagging & Analytics

Overview

Third-party cookies are dead. Apple ITP, Firefox ETP, and Chrome's phase-out have made browser-based tracking unreliable. The future is first-party data and server-side measurement — data your customers intentionally share with you that survives ad blockers, cookie restrictions, and platform changes.

This skill covers the complete measurement stack: 1P vs 3P strategy, pixel implementation, UTM architecture, server-side tagging, consent management, and identity resolution. The output is a privacy-resilient analytics infrastructure that works when cookies don't.
