Usage Patterns

Funnel Analysis Query

## Funnel Definition

### Funnel: Signup to First Value

**Steps**:
1. Page View: /signup
2. Event: signup_started
3. Event: signup_completed
4. Event: first_action_completed

**Filters**:
- Platform: web
- Date range: last 30 days
- New users only

**Segmentation**:
- By traffic source
- By device type

Funnel Query Example (Amplitude-style)

# Funnel analysis query
funnel_config = {
    "events": [
        {"event_type": "signup_started"},
        {"event_type": "signup_completed"},
        {"event_type": "onboarding_completed"},
        {"event_type": "first_value_action"}
    ],
    "filters": {
        "platform": ["web", "ios", "android"],
        "date_range": {
            "start": "2026-01-01",
            "end": "2026-01-24"
        }
    },
    "conversion_window": "7 days",
    "group_by": ["platform", "utm_source"]
}

# Expected output format
funnel_results = {
    "overall": {
        "step_1": {"users": 10000, "rate": 1.0},
        "step_2": {"users": 6500, "rate": 0.65},
        "step_3": {"users": 4200, "rate": 0.65},
        "step_4": {"users": 2100, "rate": 0.50}
    },
    "overall_conversion": 0.21,
    "segments": {
        : {: },
        : {: },
        : {: }
    }
}

Retention Analysis

## Retention Query

### Cohort Definition
- **Cohort by**: signup_date (weekly)
- **Retention event**: any_active_event
- **Time periods**: Day 1, 7, 14, 30, 60, 90

### Output: Retention Matrix

| Cohort Week | Users | D1 | D7 | D14 | D30 | D60 | D90 |
|-------------|-------|-----|-----|-----|-----|-----|-----|
| Jan 1-7 | 1000 | 45% | 30% | 25% | 20% | 15% | 12% |
| Jan 8-14 | 1200 | 48% | 32% | 27% | 22% | - | - |
| Jan 15-21 | 1100 | 46% | 31% | - | - | - | - |

Retention Query Example

# Retention analysis configuration

    "cohort_definition": {
        "event": "signup_completed",
        "grouping": "week"
    },
    "retention_event": {
        "event_type": "any_active",
        "conditions": ["page_view", "feature_used", "content_created"]

Metric Definition Specification

## Metric Specification Template

### Metric: Weekly Active Users (WAU)

**Definition**: Unique users who performed at least one qualifying action in a 7-day period.

**Calculation**:
```sql
SELECT COUNT(DISTINCT user_id)
FROM events
WHERE event_type IN ('page_view', 'feature_used', 'content_created')
  AND event_timestamp >= CURRENT_DATE - INTERVAL '7 days'

Qualifying Events:

• page_view (any page)
• feature_used
• content_created
• content_shared

Exclusions:

• Bot traffic (user_agent filter)
• Internal users (email domain filter)

Segments:

• By platform (web, ios, android)
• By subscription tier
• By signup cohort

Alerts:

• Warning: >5% week-over-week decline
• Critical: >10% week-over-week decline

### Event Tracking Specification
```json
{
  "event_name": "feature_used",

Funnel Analysis Report

# Funnel Analysis Report: Signup to First Value

## Overview
- **Period**: January 1-24, 2026
- **Total Users**: 10,000
- **Overall Conversion**: 21%

## Step-by-Step Analysis

| Step | Event | Users | Conv Rate | Drop-off |
|------|-------|-------|-----------|----------|
| 1 | signup_started | 10,000 | 100% | - |
| 2 | signup_completed | 6,500 | 65% | 35% |
| 3 | onboarding_completed | 4,200 | 65% | 35% |
| 4 | first_value_action | 2,100 | 50% | 50% |

## Key Insights

1. **Biggest Drop-off**: Step 4 (onboarding to first value) - 50% drop
2. **Best Performing Segment**: iOS users (25% overall conversion)
3. **Opportunity**: Mobile onboarding flow optimization

## Recommendations

1. Simplify first value action guidance
2. Add progress indicators in onboarding
3. Implement re-engagement for drop-offs at step 3

Best Practices

1. Define Metrics Clearly: Document calculation logic and edge cases
2. Use Consistent Time Zones: Align all queries to single timezone
3. Segment Everything: Always analyze by key user segments
4. Validate Data Quality: Check for tracking gaps and anomalies
5. Version Event Schemas: Track changes to event definitions
6. Set Appropriate Alerts: Avoid alert fatigue with meaningful thresholds
