Summary: GA4 only helps if your events and consent logic are correct. This 2025 guide shows how to debug, what to log in parameters, and how to protect conversion quality.
Debug basics
- Use DebugView to validate sequence, parameters and user properties.
- Log value where it matters (revenue, lead score).
- Deduplicate web vs. server events; keep stable event IDs.
Consent‑safe tracking
- Respect regional policies; fire limited pings until consent.
- Map consent states to tags; document fallbacks.
- Monitor modeled conversion stability after changes.
Conversion quality
Stop counting weak goals. Optimize to purchases, subscriptions and qualified leads. Align windows with your sales cycle.

Clean events + consent alignment = trustworthy optimization. Debug weekly and annotate any tagging change.
