What is GA4?

Definition

Google Analytics 4 is Google's event-based replacement for Universal Analytics. Its data model is more flexible but requires deliberate event design.

Why it matters

Understanding GA4 is foundational to working in analytics. It shapes how teams plan, communicate with stakeholders, and interpret performance.

Best practices

• → Define it in shared documentation so every team uses the same meaning.
• → Tie it to a measurable outcome rather than treating it as an end in itself.
• → Revisit assumptions quarterly — the meaning and benchmarks evolve.

Common mistakes

• → Treating it as a vanity metric instead of a decision input.
• → Copying competitors' targets without context for your funnel.
• → Optimizing it in isolation, hurting downstream conversion.
