Step 2: Configure Data Streams

Data streams are the foundation of GA4 tracking. You'll need to set up at least one web data stream for your website.

Web Data Stream Setup

  1. Add Stream: Click "Add stream" and select "Web"
  2. Website URL: Enter your website's URL (e.g., https://yourwebsite.com)

User Interactions

  • • Outbound Clicks: External website click tracking
  • • Video Engagement: Play, progress, completion
  • • File Downloads: Document and file tracking

Step 3: Install the GA4 Tracking Code

After creating your data stream, you'll receive a measurement ID (G-XXXXXXXXXX) and tracking code that needs to be installed on your website.

Manual Installation

Add the following code to the <head> section of your website:

GA4 Tracking Code
<!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=G-XXXXXXXXXX"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());
  gtag('config', 'G-XXXXXXXXXX');
</script>

WordPress Installation

If you're using WordPress, you can install the tracking code using:

  • Google Tag Manager: Install the GTM plugin and add GA4 through the interface
  • Header/Footer Plugin: Use a plugin like "Insert Headers and Footers" to add the code
  • Theme Customizer: Add the code to your theme's header.php file

WordPress Plugin Method

Add this code to your theme's functions.php file for a cleaner implementation:

WordPress GA4 Integration
// Add GA4 tracking to WordPress
function add_ga4_tracking() {
  if (!is_admin()) {
    ?>
    <!-- Google tag (gtag.js) -->
    <script async src="https://www.googletagmanager.com/gtag/js?id=G-XXXXXXXXXX"></script>
    <script>
      window.dataLayer = window.dataLayer || [];
      function gtag(){dataLayer.push(arguments);}
      gtag('js', new Date());
      gtag('config', 'G-XXXXXXXXXX');
    </script>
    <?php
  }
}
add_action('wp_head', 'add_ga4_tracking');

Shopify Installation

For Shopify stores:

  1. Go to Online Store → Themes
  2. Click "Actions" → "Edit code"
  3. Open theme.liquid in the Layout folder
  4. Add the GA4 code before the closing </head> tag

Shopify Liquid Template

Add this code to your theme.liquid file in the <head> section:

Shopify GA4 Integration
<!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=G-XXXXXXXXXX"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());
  gtag('config', 'G-XXXXXXXXXX');
</script>

<!-- Enhanced E-commerce Tracking -->
<script>
  // Track page views
  gtag('event', 'page_view', {
    'page_title': {{ page.title | json }},
    'page_location': window.location.href
  });
</script>

Step 4: Set Up Conversion Tracking

Conversion tracking is crucial for measuring marketing success. GA4 makes it easy to track both automatic and custom conversion events.

Automatic Conversion Events

GA4 automatically tracks these conversion events:

User Journey Events:

  • • first_visit: User's first visit to your website
  • • session_start: Beginning of a new user session

Engagement Events:

  • • page_view: Each page viewed by users
  • • user_engagement: User interaction with your content

Custom Conversion Events

Set up custom events for marketing-specific conversions:

Custom Conversion Events
// Track form submissions
gtag('event', 'form_submit', {
  'form_name': 'contact_form',
  'form_id': 'contact_123'
});

// Track button clicks
gtag('event', 'button_click', {
  'button_name': 'cta_button',
  'button_location': 'hero_section'
});

// Track purchases
gtag('event', 'purchase', {
  'transaction_id': 'T_12345',
  'value': 99.99,
  'currency': 'USD',
  'items': [{
    'item_id': 'SKU_12345',
    'item_name': 'Product Name',
    'price': 99.99,
    'quantity': 1
  }]
});

E-commerce Conversion Tracking

For e-commerce businesses, implement these essential events:

  • view_item: When users view product details
  • add_to_cart: When items are added to shopping cart
  • begin_checkout: When users start the checkout process
  • purchase: When orders are completed

Complete E-commerce Implementation

Here's a comprehensive e-commerce tracking setup:

Complete E-commerce Tracking
// Enhanced E-commerce Tracking for GA4

// Track product views
gtag('event', 'view_item', {
  'currency': 'USD',
  'value': 99.99,
  'items': [{
    'item_id': 'SKU_12345',
    'item_name': 'Product Name',
    'item_category': 'Category',
    'item_brand': 'Brand Name',
    'price': 99.99,
    'quantity': 1
  }]
});

// Track add to cart
gtag('event', 'add_to_cart', {
  'currency': 'USD',
  'value': 99.99,
  'items': [{
    'item_id': 'SKU_12345',
    'item_name': 'Product Name',
    'item_category': 'Category',
    'item_brand': 'Brand Name',
    'price': 99.99,
    'quantity': 1
  }]
});

// Track checkout steps
gtag('event', 'begin_checkout', {
  'currency': 'USD',
  'value': 99.99,
  'items': [{
    'item_id': 'SKU_12345',
    'item_name': 'Product Name',
    'item_category': 'Category',
    'item_brand': 'Brand Name',
    'price': 99.99,
    'quantity': 1
  }]
});

  'transaction_id': 'T_12345',
  'value': 99.99,
  'tax': 8.99,
  'shipping': 5.99,
  'currency': 'USD',
  'items': [{
    'item_id': 'SKU_12345',
    'item_name': 'Product Name',
    'item_category': 'Category',
    'item_brand': 'Brand Name',
    'price': 99.99,
    'quantity': 1
  }]
});

Step 5: Configure Goals and Conversions

In GA4, conversions are based on events rather than traditional goals. You'll need to mark specific events as conversions based on your marketing objectives.

Marking Events as Conversions

  1. Navigate to Events: Go to Configure → Events in your GA4 property
  2. Find Your Event: Locate the event you want to mark as a conversion
  3. Toggle Conversion: Click the toggle switch to mark it as a conversion
  4. Verify: The event will now appear in your Conversions report

Essential Marketing Conversions

Mark these events as conversions for comprehensive marketing tracking:

Lead Generation

  • • form_submit
  • • phone_call
  • • email_signup

E-commerce

  • • purchase
  • • add_to_cart

Step 6: Set Up Data Filters and Privacy Controls

Proper data filtering ensures data quality and privacy compliance. GA4 provides several filtering options to clean your data and respect user privacy.

Internal Traffic Filtering

Exclude internal company traffic from your reports:

  1. Go to Configure → Data Filters
  2. Click "Create Filter"
  3. Select "Internal Traffic" as the filter type
  4. Add your company's IP addresses or IP ranges
  5. Save the filter

Bot Traffic Filtering

GA4 automatically filters out known bots, but you can enhance this:

  • Enable Bot Filtering: Turn on bot filtering in your property settings
  • Custom Bot Rules: Create rules for specific bot patterns you've identified
  • Referrer Filtering: Filter traffic from known bot referrers

Privacy Compliance

Ensure your GA4 setup complies with privacy regulations:

User Consent:

  • • Cookie Consent: Implement consent banners before loading GA4
  • • User Deletion: Enable deletion requests for GDPR compliance

Data Protection:

  • • Data Retention: Set retention periods (2-14 months)
  • • IP Anonymization: Enable IP address anonymization

Step 7: Integrate with Marketing Platforms

Connect GA4 with your other marketing tools to create a unified view of your marketing performance and enable advanced attribution modeling.

Google Ads Integration

Link your GA4 property with Google Ads for enhanced campaign tracking:

  1. Go to Configure → Product Links in GA4
  2. Click "Link" next to Google Ads
  3. Select the Google Ads account you want to link
  4. Choose the linking options (we recommend enabling all)
  5. Complete the linking process

UTM Parameter Tracking

Implement comprehensive UTM parameter tracking for better campaign attribution:

UTM Parameter Tracking
// UTM Parameter Tracking for GA4

// Extract UTM parameters from URL
function getUTMParameters() {
  const urlParams = new URLSearchParams(window.location.search);
  return {
    utm_source: urlParams.get('utm_source'),
    utm_medium: urlParams.get('utm_medium'),
    utm_campaign: urlParams.get('utm_campaign'),
    utm_term: urlParams.get('utm_term'),
    utm_content: urlParams.get('utm_content')
  };
}

// Track UTM parameters with page views
gtag('event', 'page_view', {
  'page_title': document.title,
  'page_location': window.location.href,
  'custom_parameters': {
    'utm_source': getUTMParameters().utm_source,
    'utm_medium': getUTMParameters().utm_medium,
    'utm_campaign': getUTMParameters().utm_campaign,
    'utm_term': getUTMParameters().utm_term,
    'utm_content': getUTMParameters().utm_content
  }
});

// Track UTM parameters with conversions
gtag('event', 'form_submit', {
  'form_name': 'contact_form',
  'custom_parameters': {
    'utm_source': getUTMParameters().utm_source,
    'utm_medium': getUTMParameters().utm_medium,
    'utm_campaign': getUTMParameters().utm_campaign
  }
});
