• Timestamps or step indicators
• Optional: user attributes for segmentation (gender, device, location)

2. Analysis Process

Common Analysis Patterns

1. Bottleneck Identification: Find steps with highest drop-off rates
2. Segment Comparison: Compare conversion across user groups
3. Temporal Analysis: Track conversion over time
4. A/B Testing: Compare different funnel variations
5. Optimization Impact: Measure changes before/after improvements
