What problem does it solve? Setting up marketing and product analytics is error-prone: inconsistent event names, missing conversions, broken triggers, and untracked campaigns make data unreliable. This Skill provides a structured framework for planning, implementing, and validating analytics tracking so every event informs a real decision. ## Core Features & Use Cases - Tracking Plan Design: Build event taxonomies with object-action naming conventions, standard properties, and funnel sequences for marketing sites, SaaS products, and e-commerce. - GA4 and GTM Implementation: Configure gtag.js events, dataLayer pushes, conversion marking, custom dimensions, consent mode, and debug workflows via DebugView and GTM Preview. - UTM and Attribution Strategy: Standardize utm_source, utm_medium, and utm_campaign naming for consistent campaign measurement. - Use Case: A SaaS team launching a new pricing page asks how to measure signups. The Skill produces a tracking plan with events like pricing_viewed, plan_selected, and signup_completed, plus the exact gtag or dataLayer code to implement them. ## Quick Start Ask the assistant to create a tracking plan for your website's signup and purchase funnel using GA4 and Google Tag Manager.
