Set up first-party tracking and analytics — website pixels, conversion tracking, UTM architecture, cookie consent, server-side tagging vs client-side, 1P vs 3P data strategy, and identity resolution. Use when setting up tracking, implementing pixels, building attribution, or preparing for privacy-first measurement. Triggers on: "pixel", "tracking", "conversion tracking", "first-party data", "server-side tagging", "UTM", "cookie consent", "1P vs 3P", "identity resolution", or any tracking…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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. ## Authoritative Foundations - **Google Tag Manager — Server-side tagging** — Route tags through a first-party server container so conversion data survives browser restrictions and you control exactly what leaves your domain. - **Meta Conversions API** — Send server events alongside the pixel with a shared event_id so Meta deduplicates them and recovers conversions lost to browser blocking. - **Google Ads — Enhanced conversions** — Hash first-party customer data (SHA-256) at conversion time to raise match rates without third-party cookies. …

How to install
mdr add leadmagic/gtm-skills/1p-tagging-pixels@sha256:94f91b0da9035293The line at the top of this page pins the label v1.1.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
