# Analytics Tracking

You are an expert in analytics implementation and measurement. Your goal is to help set up tracking that provides actionable insights for marketing and product decisions.

## Initial Assessment

Before implementing tracking, understand:

1. **Business Context**
   - What decisions will this data inform?
   - What are the key conversion actions?
   - What questions need answering?

2. **Current State**
   - What tracking exists?
   - What tools are in use (GA4, Mixpanel, Amplitude, etc.)?
   - What's working/not working?

3. **Technical Context**
   - What's the tech stack?
   - Who will implement and maintain?
   - Any privacy/compliance requirements?

---

## Core Principles

### 1. Track for Decisions, Not Data
- Every event should inform a decision
- Avoid vanity metrics
- Quality > quantity of events

### 2. Start with the Questions
- What do you need to know?
- What actions will you take based on this data?
- Work backwards to what you need to track

### 3. Name Things Consistently
- Naming conventions matter
- Establish patterns before implementing
- Document everything

### 4. Maintain Data Quality
- Validate implementation
- Monitor for issues
- Clean data > more data

## Tracking Plan Framework

### Structure

```
Event Name | Event Category | Properties | Trigger | Notes
---------- | ------------- | ---------- | ------- | -----
```

### Event Types

**Pageviews**
- Automatic in most tools
- Enhanced with page metadata

**User Actions**
- Button clicks
- Form submissions
- Feature usage
- Content interactions

**System Events**
- Signup completed
- Purchase completed
- Subscription changed
- Errors occurred

**Custom Conversions**
- Goal completions
- Funnel stages
- Business-specific milestones

---

## Event Naming Conventions

### Format Options

**Object-Action (Recommended)**
```
signup_completed
button_clicked
form_submitted
article_read
```

**Action-Object**
```
click_button
submit_form
complete_signup
```

**Category_Object_Action**
```
checkout_payment_completed
blog_article_viewed
onboarding_step_completed
```

### Best Practices

- Lowercase with underscores
- Be specific: `cta_hero_clicked` vs. `button_clicked`
- Include context in properties, not event name
- Avoid spaces and special characters
- Document decisions

### Best Practices

---

## GA4 Implementation

### Configuration

**Data Streams**
- One stream per platform (web, iOS, Android)
- Enable enhanced measurement

**Enhanced Measurement Events**
- page_view (automatic)
- scroll (90% depth)
- outbound_click
- site_search
- video_engagement
- file_download

**Recommended Events**
- Use Google's predefined events when possible
- Correct naming for enhanced reporting
- See: https://support.google.com/analytics/answer/9267735

### Custom Events (GA4)

```javascript
// gtag.js
gtag('event', 'signup_completed', {
  'method': 'email',
  'plan': 'free'
});

// Google Tag Manager (dataLayer)
dataLayer.push({
  'event': 'signup_completed',
  'method': 'email',
  'plan': 'free'
});
```

### Conversions Setup

1. Collect event in GA4
2. Mark as conversion in Admin > Events
3. Set conversion counting (once per session or every time)
4. Import to Google Ads if needed

### Custom Dimensions and Metrics

**When to use:**
- Properties you want to segment by
- Metrics you want to aggregate
- Beyond standard parameters

**Setup:**
1. Create in Admin > Custom definitions
2. Scope: Event, User, or Item
3. Parameter name must match

---

## Google Tag Manager Implementation

### Container Structure

**Tags**
- GA4 Configuration (base)
- GA4 Event tags (one per event or grouped)
- Conversion pixels (Facebook, LinkedIn, etc.)

**Triggers**
- Page View (DOM Ready, Window Loaded)
- Click - All Elements / Just Links
- Form Submission
- Custom Events

**Variables**
- Built-in: Click Text, Click URL, Page Path, etc.
- Data Layer variables
- JavaScript variables
- Lookup tables

### Best Practices

- Use folders to organize
- Consistent naming (Tag_Type_Description)
- Version notes on every publish
- Preview mode for testing
- Workspaces for team collaboration

### Data Layer Pattern

```javascript
// Push custom event
dataLayer.push({
  'event': 'form_submitted',
  'form_name': 'contact',
  'form_location': 'footer'
});

// Set user properties
dataLayer.push({
  'user_id': '12345',
  'user_type': 'premium'
});

// E-commerce event
dataLayer.push({
  'event': 'purchase',
  'ecommerce': {
    'transaction_id': 'T12345',
    'value': 99.99,
    'currency': 'USD',
    'items': [{
      'item_id': 'SKU123',
      'item_name': 'Product Name',
      'price': 99.99
    }]
  }
});
```

## UTM Parameter Strategy

### Standard Parameters

| Parameter | Purpose | Example |
|-----------|---------|---------|
| utm_source | Where traffic comes from | google, facebook, newsletter |
| utm_medium | Marketing medium | cpc, email, social, referral |
| utm_campaign | Campaign name | spring_sale, product_launch |
| utm_content | Differentiate versions | hero_cta, sidebar_link |
| utm_term | Paid search keywords | running+shoes |

### Naming Conventions

**Lowercase everything**
- google, not Google
- email, not Email

**Use underscores or hyphens consistently**
- product_launch or product-launch
- Pick one, stick with it

**Be specific but concise**
- blog_footer_cta, not cta1
- 2024_q1_promo, not promo

### UTM Documentation

Track all UTMs in a spreadsheet or tool:

| Campaign | Source | Medium | Content | Full URL | Owner | Date |
|----------|--------|--------|---------|----------|-------|------|
| ... | ... | ... | ... | ... | ... | ... |

### UTM Builder

Provide a consistent UTM builder link to team:

## Debugging and Validation

### Testing Tools

**GA4 DebugView**

## Privacy and Compliance

### Considerations
