GA4 and GTM Notes

GA4 and Google Tag Manager stay maintainable when event names, parameters, triggers, consent behavior, and release notes follow a shared convention. The goal is not only to fire tags; it is to preserve analytics data that another analyst or developer can understand later.

Event and parameter design

• Model events around user actions, not page mechanics.
• Reuse a small, consistent set of parameter names.
• Register custom dimensions deliberately, not reactively.
• Keep recommended event names where GA4 expects them.

Naming conventions

• Use lowercase, underscored, predictable event names.
• Document the convention so new tags stay consistent.
• Avoid synonyms for the same action across templates.

Container hygiene

• Use a clean data layer as the source for tags.
• Prefer fewer, well-named triggers over many ad hoc ones.
• Use folders, naming, and notes to keep the container readable.
• Version and document significant changes.

Debugging

• Validate in Preview and the GA4 DebugView before publishing.
• Check parameter values, not just that an event fired.
• Confirm consent state changes behave as expected.
• Watch for duplicate or double-counted events.

These notes pair with the analytics implementation checklist linked below, which covers what to define before any of this is built.
