Purpose
Build and analyze conversion funnels to identify where users drop off, why they leave, and what to fix — turning raw event data into prioritized improvement campaigns.
Application
Step 1: Define the Funnel
## Funnel: [Name — e.g., "Trial to Paid"]
| Step | Event | Definition |
|------|-------|-----------|
| 1 | [Landing page visit] | [User arrives on landing page] |
| 2 | [Signup started] | [User clicks "Start trial"] |
| 3 | [Signup completed] | [User completes registration] |
| 4 | [Onboarding started] | [User begins setup] |
| 5 | [Activated] | [User completes activation event] |
| 6 | [Converted] | [User starts paid subscription] |
Step 2: Measure Conversion
| Step | Users | Conv. Rate | Drop-off |
|------|-------|-----------|---------|
| Landing page | 10,000 | — | — |
| Signup started | 3,200 | 32% | 68% |
| Signup completed | 2,400 | 75% | 25% |
| Onboarding | 1,800 | 75% | 25% |
| Activated | 670 | 37% | 63% |
| Converted | 252 | 38% | 62% |
**Overall funnel conversion:** 2.5%
**Biggest drop-offs:** Landing → Signup (68%), Onboarding → Activated (63%)
Step 3: Diagnose Drop-offs
For each significant drop-off:
### Drop-off: [Step A] → [Step B] ([%] drop)
**Hypotheses:**
1. [Reason — e.g., "Form is too long"] → Evidence: [Data/research]
2. [Reason] → Evidence: [Data]
**Recommended intervention:**
- [What to test + expected impact]
Step 4: Prioritize Improvements
| Leaky Step | Drop-off % | Potential Lift | Effort | Priority |
|-----------|-----------|---------------|--------|----------|
| [Step] | [%] | [Est. users saved] | [S/M/L] | [1/2/3] |
