Getting Started: How to Ask Claude for Help

The quality of Claude’s help depends on how you frame your request. Here is how to get the best results.

Be Specific About Your Platform

Instead of: “Help me set up tracking”
Say: “I need to track purchases on my Shopify store using Google Tag Manager for Google Ads conversion tracking. My checkout uses Shopify’s native checkout.”
Include Relevant Context
Helpful details to include:

• Helpful details to include when asking Claude for assistance with tracking implementations, especially when working with platforms where Google Tag Manager is better than installing scripts manually.
• Your ecommerce platform (Shopify, WooCommerce, BigCommerce)
• Your website technology (WordPress, React, Next.js, Framer)
• What you want to track (purchases, form submissions, phone calls)
• What you have already set up (GTM installed, GA4 configured)
• Any specific issues you are encountering
• Share Error Messages or Screenshots
  If troubleshooting, tell Claude:
• What you expected to happen
• What actually happened
• Any error messages you see
• What you see in GTM Preview Mode

Example 1: Creating a Purchase Data Layer

You need a data layer push for your ecommerce purchases.

What to Ask Claude

“I need a data layer push script for purchase events that works with Google Ads conversion tracking. My ecommerce platform provides these variables on the thank you page: order ID, order total, currency, and product details. Can you create the data layer code?”
Claude’s Response
Claude will provide code like this:

<script>
window.dataLayer = window.dataLayer || [];
window.dataLayer.push({
  event: "purchase",
  ecommerce: {
    transaction_id: "ORDER-12345",      // Replace with dynamic order ID
    value: 149.99,                       // Replace with dynamic order total
    currency: "USD",                     // Replace with dynamic currency
    tax: 12.00,                          // Optional: tax amount
    shipping: 5.99,                      // Optional: shipping cost
    items: [
      {
        item_id: "SKU-001",              // Product SKU
        item_name: "Product Name",        // Product name
        price: 149.99,                    // Product price
        quantity: 1                       // Quantity purchased
      }
    ]
  }
});
</script>

Follow-Up Questions

Ask Claude to customize:

• “Can you modify this for Shopify’s checkout where I access data via Liquid?”
• “How do I make this work with WooCommerce’s order data?”
• “Can you add support for multiple products in the cart?”

Example 2: Setting Up Google Ads Conversion Tag

You need help configuring the actual GTM tags.

What to Ask Claude

“I have the purchase data layer set up. Now I need to create the Google Ads conversion tag in GTM. My conversion ID is AW-123456789 and my conversion label is AbCdEfGh. Walk me through the setup.”

Claude’s Response

Claude will provide step-by-step instructions:
Step 1: Create Data Layer Variables

• Go to Variables → New → Data Layer Variable
• Create these variables:

Variable Name	Data Layer Variable Name
DLV – transaction_id	ecommerce.transaction_id
DLV – value	ecommerce.value
DLV – currency	ecommerce.currency

• 
  Step 2: Create the Trigger
• Go to Triggers → New
• Name: “Event – Purchase”
• Type: Custom Event
• Event name: purchase
• Save
• Step 3: Create the Google Ads Conversion Tag
• Go to Tags → New
• Name: “Google Ads – Purchase Conversion”
• Type: Google Ads Conversion Tracking
• Configuration:
  • Conversion ID: AW-123456789
  • Conversion Label: AbCdEfGh
  • Conversion Value: {{DLV – value}}
  • Currency Code: {{DLV – currency}}
  • Transaction ID: {{DLV – transaction_id}}
• Trigger: Event – Purchase
• Save
• Step 4: Add Conversion Linker
• Go to Tags → New
• Name: “Conversion Linker”
• Type: Conversion Linker
• Trigger: All Pages
• Save

Example 3: Troubleshooting a Conversion Issue

Your conversion tag is not firing or showing zero value.

What to Ask Claude

“My Google Ads purchase conversion tag fires according to GTM Preview, but the conversion value shows as undefined. Here’s what I see in the data layer:

{
  event: 'purchase',
  transactionId: '12345',
  transactionTotal: 99.99
}

• My variable is set to read ecommerce.value but it’s coming back undefined. What’s wrong?”

Claude’s Response

Claude will identify the issue:
“The problem is a mismatch between your data layer structure and your variable configuration.
Your data layer uses:

• transactionId
•  (not 
• ecommerce.transaction_id
• )
• transactionTotal
•  (not 
• ecommerce.value
• )
• Your variable expects:
• ecommerce.value
• Solution:
  Either update your data layer to match the expected structure:

window.dataLayer.push({
  event: 'purchase',
  ecommerce: {
    transaction_id: '12345',
    value: 99.99,
    currency: 'USD'
  }
});

• Or update your GTM variables to match your current structure:

Variable Name	Data Layer Variable Name
DLV – transaction_id	transactionId
DLV – value	transactionTotal

• I recommend updating the data layer to use the GA4/Google standard ecommerce structure, as this ensures compatibility with GA4 and other Google tags.”

Example 4: Creating Custom JavaScript Variables
You need to extract or transform data.

What to Ask Claude

“I need a custom JavaScript variable that extracts just the email domain from a full email address in my data layer. The email is stored in user.email.”

Claude’s Response

function() {
  var email = {{DLV - user.email}};
  
  if (!email || typeof email !== 'string') {
    return undefined;
  }
  
  var parts = email.split('@');
  
  if (parts.length === 2) {
    return parts[1].toLowerCase();
  }
  
  return undefined;
}

• “Create this as a Custom JavaScript variable in GTM. It:
• Gets the email from your data layer variable
• Validates that it exists and is a string
• Use cases:
• Segment conversions by email provider
• Identify B2B vs B2C leads (company domains vs gmail/yahoo)
• Filter internal test conversions”
•  
• Splits on the @ symbol
• Returns the domain portion in lowercase
• Returns undefined if the email is invalid

Tips for Working with Claude on GTM

Iterate and Refine

Start with a basic request, then refine:

• “Create a purchase data layer for Shopify”
• “Add support for discount codes”
• “Include customer email for Enhanced Conversions”
• “Make it work with Shopify’s checkout extensibility”
• Ask for Explanations
  Understanding helps you maintain the implementation:
• “Why do we need the Conversion Linker tag?”
• “What does wait_for_update do in Consent Mode?”
• “Why use ecommerce.value instead of just value?”
• Request Variations
  Get multiple approaches:
• “What are different ways to track form submissions in GTM?”
• “Show me both the data layer approach and the DOM scraping approach”
• Ask for Testing Steps
  Always request verification:
• “How do I test this in GTM Preview Mode?”
• “What should I see in the data layer?”
• “How do I verify conversions in Google Ads?”
• Share Your Results
  When troubleshooting, share what happened:
• “I implemented your code and here’s what I see…”
• “The tag fires but the value shows as…”
• “I get this error in the console…”
