GTM Tracking Setup

Design tracking configurations for GA4, GTM, and each ad platform, and output an importable JSON file for the GTM container.

Workflow

0. Read app code → 1. Gather requirements → 2. Consult references → 3. Refer to examples → 4. Output JSON → 5. Implementation guide

0. Reading the application code

If the source code of the site/app to be tracked exists within the project (e.g., under dev/), always read and understand it before starting design. Understanding the actual code dramatically improves the precision of dataLayer design, trigger conditions, and event definitions.
