What problem does it solve? Marketing and product teams often collect inconsistent or low-quality analytics data, making it impossible to trust reports or measure conversions. This Skill provides a structured framework for planning, implementing, and validating event tracking so every data point supports a real decision. ## Core Features & Use Cases - Tracking Plan Design: Build a complete event taxonomy with naming conventions, event properties, and conversion definitions for marketing sites, SaaS products, and e-commerce. - GA4 & GTM Implementation: Get ready-to-use gtag.js and dataLayer code snippets, custom dimension setup, and conversion configuration guidance. - UTM Governance: Establish consistent UTM naming conventions and documentation practices for campaign attribution. - Use Case: A growth team launching a new signup funnel asks for a tracking plan; the Skill produces an event table (signup_started, signup_completed with method/plan properties), GTM dataLayer code, and a validation checklist. ## Quick Start Ask the assistant to create a GA4 tracking plan for your website's signup and checkout funnel, including event names, properties, and GTM dataLayer code.
