Analytics Governance & Data Quality Framework.

Build a clear understanding of how Google Tag Manager and Google Analytics 4 work together before jumping into implementation. This beginner-friendly guide walks you through the core concepts behind tags, triggers, variables, the Data Layer, consent, Preview Mode, and debugging—helping you understand how data moves from a website into GA4 and how to recognize when something isn’t working as expected.

Designed as the foundation for more practical implementation work, the guide focuses on understanding the system rather than simply following setup instructions, so you can approach tracking with more confidence and make sense of what you see inside GTM and GA4.
