Refactor remaining skills for progressive disclosure

Phase 2 refactoring of skills >500 lines and medium-sized skills:

- paid-ads: 553 → 297 lines
  - Extract ad-copy-templates.md, audience-targeting.md, platform-setup-checklists.md

- analytics-tracking: 541 → 292 lines
  - Extract ga4-implementation.md, gtm-implementation.md, event-library.md

- ab-test-setup: 510 → 264 lines
  - Extract test-templates.md, sample-size-guide.md

- copywriting: 458 → 248 lines
  - Extract copy-frameworks.md (headline formulas, section types)

- page-cro: 336 → 180 lines
  - Extract experiments.md (experiment ideas by page type)

- onboarding-cro: 435 → 218 lines
  - Extract experiments.md (onboarding experiment ideas)

All skills now use progressive disclosure with references/ folders,
keeping SKILL.md files focused on core workflow while detailed
content is available when needed.

---
## GA4 Implementation
### Configuration
### Quick Setup
**Data Streams**
- One stream per platform (web, iOS, Android)
- Enable enhanced measurement
1. Create GA4 property and data stream
2. Install gtag.js or GTM
3. Enable enhanced measurement
4. Configure custom events
5. Mark conversions in Admin
**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)
### Custom Event Example
```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
**For detailed GA4 implementation**: See [references/ga4-implementation.md](references/ga4-implementation.md)
---
## Google Tag Manager Implementation
## Google Tag Manager
### 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
| Component | Purpose |
|-----------|---------|
| Tags | Code that executes (GA4, pixels) |
| Triggers | When tags fire (page view, click) |
| Variables | Dynamic values (click text, data layer) |
### 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
}]
}
});
```

- product_launch or product-launch
- Pick one, stick with it
**Be specific but concise**
- blog_footer_cta, not cta1

- Internal tool
- Spreadsheet formula
- Lowercase everything
- Use underscores or hyphens consistently
- Be specific but concise: `blog_footer_cta`, not `cta1`

```javascript
// Basic event
gtag('event', 'signup_completed', {
'method': 'email',
'plan': 'free'
});
// Event with value
gtag('event', 'purchase', {
'transaction_id': 'T12345',
'value': 99.99,
'currency': 'USD',
'items': [{
'item_id': 'SKU123',
'item_name': 'Product Name',
'price': 99.99
}]

// Clear ecommerce before sending (best practice)
dataLayer.push({ ecommerce: null });
dataLayer.push({
'event': 'view_item',
'ecommerce': {
// ...
}
});
```

## Conversions Setup
### Creating Conversions
1. **Collect the event** - Ensure event is firing in GA4
2. **Mark as conversion** - Admin > Events > Mark as conversion
3. **Set counting method**:
- Once per session (leads, signups)
- Every event (purchases)
4. **Import to Google Ads** - For conversion-optimized bidding
### Conversion Values
```javascript
// Event with conversion value
gtag('event', 'purchase', {
'value': 99.99,
'currency': 'USD'
});
```
Or set default value in GA4 Admin when marking conversion.

## Custom Dimensions and Metrics
### When to Use
**Custom dimensions:**
- Properties you want to segment/filter by
- User attributes (plan type, industry)
- Content attributes (author, category)
**Custom metrics:**
- Numeric values to aggregate
- Scores, counts, durations
### Setup Steps
1. Admin > Data display > Custom definitions
2. Create dimension or metric
3. Choose scope:
- **Event**: Per event (content_type)
- **User**: Per user (account_type)
- **Item**: Per product (product_category)
4. Enter parameter name (must match event parameter)
### Examples
| Dimension | Scope | Parameter | Description |
|-----------|-------|-----------|-------------|
| User Type | User | user_type | Free, trial, paid |
| Content Author | Event | author | Blog post author |
| Product Category | Item | item_category | E-commerce category |
---
## Audiences
### Creating Audiences
Admin > Data display > Audiences
**Use cases:**
- Remarketing audiences (export to Ads)
- Segment analysis
- Trigger-based events
### Audience Examples
**High-intent visitors:**
- Viewed pricing page
- Did not convert
- In last 7 days
**Engaged users:**
- 3+ sessions
- Or 5+ minutes total engagement
**Purchasers:**
- Purchase event
- For exclusion or lookalike

# Google Tag Manager Implementation Reference
Detailed guide for implementing tracking via Google Tag Manager.
## Container Structure
### Tags
Tags are code snippets that execute when triggered.
**Common tag types:**
- GA4 Configuration (base setup)
- GA4 Event (custom events)
- Google Ads Conversion
- Facebook Pixel
- LinkedIn Insight Tag
- Custom HTML (for other pixels)
### Triggers
Triggers define when tags fire.
**Built-in triggers:**
- Page View: All Pages, DOM Ready, Window Loaded
- Click: All Elements, Just Links
- Form Submission
- Scroll Depth
- Timer
- Element Visibility
**Custom triggers:**
- Custom Event (from dataLayer)
- Trigger Groups (multiple conditions)
### Variables
Variables capture dynamic values.
**Built-in (enable as needed):**
- Click Text, Click URL, Click ID, Click Classes
- Page Path, Page URL, Page Hostname
- Referrer
- Form Element, Form ID
**User-defined:**
- Data Layer variables
- JavaScript variables
- Lookup tables
- RegEx tables
- Constants
---
## Naming Conventions
### Recommended Format
```
[Type] - [Description] - [Detail]
Tags:
GA4 - Event - Signup Completed
GA4 - Config - Base Configuration
FB - Pixel - Page View
HTML - LiveChat Widget
Triggers:
Click - CTA Button
Submit - Contact Form
View - Pricing Page
Custom - signup_completed
Variables:
DL - user_id
JS - Current Timestamp
LT - Campaign Source Map
```
---
## Data Layer Patterns
### Basic Structure
```javascript
// Initialize (in <head> before GTM)
window.dataLayer = window.dataLayer || [];
// Push event
dataLayer.push({
'event': 'event_name',
'property1': 'value1',
'property2': 'value2'
});
```
### Page Load Data
```javascript
// Set on page load (before GTM container)
window.dataLayer = window.dataLayer || [];
dataLayer.push({
'pageType': 'product',
'contentGroup': 'products',
'user': {
'loggedIn': true,
'userId': '12345',
'userType': 'premium'
}
});
```
### Form Submission
```javascript
document.querySelector('#contact-form').addEventListener('submit', function() {
dataLayer.push({
'event': 'form_submitted',
'formName': 'contact',
'formLocation': 'footer'
});
});
```
### Button Click
```javascript
document.querySelector('.cta-button').addEventListener('click', function() {
dataLayer.push({
'event': 'cta_clicked',
'ctaText': this.innerText,
'ctaLocation': 'hero'
});
});
```
### E-commerce Events
```javascript
// Product view
dataLayer.push({ ecommerce: null }); // Clear previous
dataLayer.push({
'event': 'view_item',
'ecommerce': {
'items': [{
'item_id': 'SKU123',
'item_name': 'Product Name',
'price': 99.99,
'item_category': 'Category',
'quantity': 1
}]
}
});
// Add to cart
dataLayer.push({ ecommerce: null });
dataLayer.push({
'event': 'add_to_cart',
'ecommerce': {
'items': [{
'item_id': 'SKU123',
'item_name': 'Product Name',
'price': 99.99,
'quantity': 1
}]
}
});
// Purchase
dataLayer.push({ ecommerce: null });
dataLayer.push({
'event': 'purchase',
'ecommerce': {
'transaction_id': 'T12345',
'value': 99.99,
'currency': 'USD',
'tax': 5.00,
'shipping': 10.00,
'items': [{
'item_id': 'SKU123',
'item_name': 'Product Name',
'price': 99.99,
'quantity': 1
}]
}
});
```

## Common Tag Configurations
### GA4 Configuration Tag
**Tag Type:** Google Analytics: GA4 Configuration
**Settings:**
- Measurement ID: G-XXXXXXXX
- Send page view: Checked (for pageviews)
- User Properties: Add any user-level dimensions
**Trigger:** All Pages
### GA4 Event Tag
**Tag Type:** Google Analytics: GA4 Event
**Settings:**
- Configuration Tag: Select your config tag
- Event Name: {{DL - event_name}} or hardcode
- Event Parameters: Add parameters from dataLayer
**Trigger:** Custom Event with event name match
### Facebook Pixel - Base
**Tag Type:** Custom HTML
```html
<script>
!function(f,b,e,v,n,t,s)
{if(f.fbq)return;n=f.fbq=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};
if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];
s.parentNode.insertBefore(t,s)}(window, document,'script',
'https://connect.facebook.net/en_US/fbevents.js');
fbq('init', 'YOUR_PIXEL_ID');
fbq('track', 'PageView');
</script>
```
**Trigger:** All Pages
### Facebook Pixel - Event
**Tag Type:** Custom HTML
```html
<script>
fbq('track', 'Lead', {
content_name: '{{DL - form_name}}'
});
</script>
```
**Trigger:** Custom Event - form_submitted

## Preview and Debug
### Preview Mode
1. Click "Preview" in GTM
2. Enter site URL
3. GTM debug panel opens at bottom
**What to check:**
- Tags fired on this event
- Tags not fired (and why)
- Variables and their values
- Data layer contents
### Debug Tips
**Tag not firing:**
- Check trigger conditions
- Verify data layer push
- Check tag sequencing
**Wrong variable value:**
- Check data layer structure
- Verify variable path (nested objects)
- Check timing (data may not exist yet)
**Multiple firings:**
- Check trigger uniqueness
- Look for duplicate tags
- Check tag firing options
---
## Workspaces and Versioning
### Workspaces
Use workspaces for team collaboration:
- Default workspace for production
- Separate workspaces for large changes
- Merge when ready
### Version Management
**Best practices:**
- Name every version descriptively
- Add notes explaining changes
- Review changes before publish
- Keep production version noted
**Version notes example:**
```
v15: Added purchase conversion tracking
- New tag: GA4 - Event - Purchase
- New trigger: Custom Event - purchase
- New variables: DL - transaction_id, DL - value
- Tested: Chrome, Safari, Mobile
```
---
## Consent Management
### Consent Mode Integration
```javascript
// Default state (before consent)
gtag('consent', 'default', {
'analytics_storage': 'denied',
'ad_storage': 'denied'
});
// Update on consent
function grantConsent() {
gtag('consent', 'update', {
'analytics_storage': 'granted',
'ad_storage': 'granted'
});
}
```
### GTM Consent Overview
1. Enable Consent Overview in Admin
2. Configure consent for each tag
3. Tags respect consent state automatically
---
## Advanced Patterns
### Tag Sequencing
**Setup tags to fire in order:**
Tag Configuration > Advanced Settings > Tag Sequencing
**Use cases:**
- Config tag before event tags
- Pixel initialization before tracking
- Cleanup after conversion
### Exception Handling
**Trigger exceptions** - Prevent tag from firing:
- Exclude certain pages
- Exclude internal traffic
- Exclude during testing
### Custom JavaScript Variables
```javascript
// Get URL parameter
function() {
var params = new URLSearchParams(window.location.search);
return params.get('campaign') || '(not set)';
}
// Get cookie value
function() {
var match = document.cookie.match('(^|;) ?user_id=([^;]*)(;|$)');
return match ? match[2] : null;
}
// Get data from page
function() {
var el = document.querySelector('.product-price');
return el ? parseFloat(el.textContent.replace('$', '')) : 0;
}
```
