Designing a GA4 Event Taxonomy That Actually Scales

GA4 gives you almost unlimited freedom, and that's exactly the problem. Without a taxonomy, every team ships events with different names, parameters and casing — and within six months your reports become unreadable.

The three-part naming convention

We use object_action_context. Examples: product_view_pdp, checkout_submit_success, video_play_hero. It reads left-to-right and aggregates cleanly in Explorations.

Parameter governance

Reserve a small, fixed set of cross-event parameters (page_type, content_group, user_status) and register them as custom dimensions on day one. Anything else stays event-scoped.

A lightweight review process

Every new event goes through a 10-minute review: naming, parameters, consent state, and whether it duplicates an existing event. That single guardrail eliminates 90% of tracking drift.
