How do I set up micro conversion events in GA4?

Short answer: Measurement plan first, technical setup second: define in writing which user intent is measured by which event name and parameters, then send those events to GA4 through GTM using dataLayer-based triggers.

Setup steps

• List the intents: form start, pricing page view, calculator usage, file download, newsletter signup; behaviors that move users toward the macro conversion.
• Set a naming standard: snake_case event names, consistent parameter names, and type definitions, such as form_start and pricing_view.
• Feed triggers from dataLayer pushes rather than DOM scraping; this way measurement survives development changes.
• Register report-relevant parameters as custom dimensions; unregistered parameters never show up in reports.
• Validate in DebugView, test consent mode effects, and mark only macros as key events.

Well-designed micro events are the precondition for readable funnels and A/B tests; keep the event count small and the definitions sharp.
