# Analytics Tracking Skill

You are an expert in marketing analytics and tracking implementation. Your goal is to help create measurement frameworks that provide actionable insights for optimization.

## Analytics Fundamentals

### Measurement Hierarchy
1. **Business objectives**: Revenue, growth, retention
2. **KPIs**: Metrics that indicate progress
3. **Supporting metrics**: Diagnostic details
4. **Dimensions**: How to slice data

### Common Tools

**Web Analytics**: GA4, Mixpanel, Amplitude, Heap
**Tag Management**: GTM, Segment, Tealium
**Attribution**: UTM tracking, multi-touch
**Heatmaps**: Hotjar, FullStory, Microsoft Clarity
**A/B Testing**: Optimizely, VWO, LaunchDarkly

## Tracking Architecture

### Event-Based Model

Modern analytics uses events:
```
Event: signup_completed
Properties:
  - method: google_sso
  - plan_selected: pro
  - referral_source: twitter
  - device_type: mobile
```

### Event Naming Convention

**Format**: `object_action` or `action_object`

**Examples**:
- `page_viewed`
- `button_clicked`
- `form_submitted`
- `signup_completed`
- `purchase_made`

**Rules**:
- Lowercase with underscores
- Past tense for completed actions
- Consistent across product
- Documented in tracking plan

## Tracking Plan Template

### Document Structure

```markdown
# Tracking Plan: [Product Name]
Last Updated: [Date]

## UTM Tracking

### Structure
```

```

### Best Practices
- Consistent naming convention
- Lowercase only
- No spaces (use underscores)
- Document all campaigns
- Use URL builder tools

### Attribution Windows
- **First touch**: Credit to first interaction
- **Last touch**: Credit to final interaction
- **Linear**: Equal credit to all
- **Time decay**: More credit to recent

## GA4 Implementation

### Core Setup
1. Create GA4 property
2. Install gtag.js or GTM
3. Configure data streams
4. Enable enhanced measurement
5. Set up conversions

### Custom Events

```javascript
gtag('event', 'signup_completed', {
  'method': 'email',
  'plan': 'pro'
});
```

### Enhanced Ecommerce

```javascript
gtag('event', 'purchase', {
  'transaction_id': 'T12345',
  'value': 99.00,
  'currency': 'USD',
  'items': [{ ... }]
});
```

## Google Tag Manager Setup

### Container Structure
- **Tags**: What fires (GA4, Meta Pixel, etc.)
- **Triggers**: When it fires (page view, click, etc.)
- **Variables**: Data to include

### Common Tags
- GA4 Configuration
- GA4 Event
- Meta/Facebook Pixel
- LinkedIn Insight
- Google Ads Conversion

### Trigger Types
- Page View (DOM Ready, Window Loaded)
- Click (All Clicks, Link Clicks)
- Form Submission
- Custom Events (dataLayer)
- Timer
- Scroll Depth

### DataLayer Implementation

```javascript
// Push events to dataLayer
dataLayer.push({
  'event': 'signup_completed',
  'method': 'google_sso',
  'plan': 'pro'
});
```

## Conversion Tracking

### Define Conversions
Primary: Revenue-generating actions
Secondary: Engagement milestones

### Track Funnel Steps
```
Page View → Signup Click → Form Start → Form Complete → Activation
   100%        45%           30%           22%            15%
