Why use a tracking plan?
The gap between “I want to track conversions” and a working setup is massive. Most teams guess their way through GTM using fragile CSS selectors that break the next time a developer changes a button colour.
A tracking plan gives you explicit dataLayer.push()payloads. This moves tracking ownership to the codebase, where it's robust, version-controlled, and testable.
DOM selectors vs dataLayer events
Fragile: “Track clicks on .btn-primary” — breaks the next deploy.
Bulletproof: “Track dataLayer generate_leadevent” — deliberate, documented, version-controlled.
Once your developers implement the code above, run our Audit Engine to verify the data is routing correctly to GA4.
