Free Shopify Enhanced Conversion Tracking Pixel For Google Ads + Micro Conversions + GA4

If you have multiple Google Merchant Center accounts and or you have different feeds, contact us for custom coding. You may also contact us for any other custom coding.

What is New?

• V1.05+ now supports cart data, for using cost of goods based bidding strategy in Google Ads
• V1.07+ now supports micro conversions + bug fixes
• V1.08+ now supports Google Analtyics 4 (optional)

What is the difference between Micro and Macro Conversions?

When it comes to advertising, we have two types of conversions. Macro and Micro conversions. Macro conversions are the website’s primary conversions, such as completing an order or submitting a lead form. Micro conversions are smaller actions such as add to cart, view cart, add a delivery address, etc.

Requirements

You need access to the following accounts.

• Google Tag Manager
• Google Ads
• Google Analytics 4
• Shopify (Customer Events)

Let’s get started!

If you have not yet created a Google Tag Manager account, create one now.

Once the account is created, you should see a popup with your GTM tag, if you don’t see this, don’t worry, simply go to Admin > Install Google Tag Manager

Copy the tag id without GTM- as highlighted in the image below

Replace the following values in the settings:

• GOOGLE_TAG_MANAGER_ID
  • Add your GTM tag ID
• GOOGLE_MERCHANT_CENTER_ID
  • Add your Google Merchant Center account ID
• PRODUCT_COUNTRY_CODE
  • Set your default country ISO2 code, for usage in product IDs
• ESTIMATED_SHIPPING_TIME
  • Add your estimated shipping time
• GRANT_CONSENT
  • Defaulted to false, if you set it to true, you are forcing to set consent_mode v2 to true, regardless what the use selected (not recommended)
• ID_TYPE
  • Set your Google Merchant Center product ID format
• CAPITALIZE_SKU
  • If you are not using the default Shopify IDs and you are using SKUs, you can choose to uppercase the value

In the code below replace GTM-123456 with your GTM tag ID

// Code Created By FeedArmy V1.0814 (please don't remove the creator)
// Copyright FeedArmy Co., Ltd.

const GOOGLE_TAG_MANAGER_ID = 'GTM-123456';
const GOOGLE_MERCHANT_CENTER_ID = '123456789';
const PRODUCT_COUNTRY_CODE = 'US';
const ESTIMATED_SHIPPING_TIME = 5;
const GRANT_CONSENT = false; // Use false or true

// for the ID_TYPE, if your products look like shopify_US_123456789_123456798 add the word shopify
// if your products are sku's add the value sku -- const ID_TYPE = 'sku';
// if your proudcts use the variant id use the value variant_id -- const ID_TYPE = 'variant_id';
// if your proudcts use the parent id use the value parent_id -- const ID_TYPE = 'parent_id';

const ID_TYPE = 'shopify';

// If you want to capitalize the SKU set CAPITALIZE_SKU to true, if you don't want to change anything set to false
const CAPITALIZE_SKU = false;

Now go to Shopify > Settings > Customer Events

And click on Add custom pixel

You can give it any pixel name, but I will call it Google Ads Conversion. Now click on Add pixel.

When editing the code below, please do not remove or change the author, and respect who built it.

// Created by FeedArmy V1.04

Paste the below code in the Shopify pixel.

// Created by FeedArmy V1.05
const script = document.createElement('script');
script.setAttribute('src', 'https://www.googletagmanager.com/gtag/js?id=AW-123456789');
script.setAttribute('async', '');
document.head.appendChild(script);

window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'AW-123456789', {'allow_enhanced_conversions':true});

analytics.subscribe("checkout_completed", (event) => {
  gtag('set', 'user_data', {
    email: event.data?.checkout?.email,
    phone: event.data?.checkout?.phone,
    address: {
      first_name: event.data?.checkout?.shippingAddress?.firstName,
      last_name: event.data?.checkout?.shippingAddress?.lastName,
      street: event.data?.checkout?.shippingAddress?.address1,
      city: event.data?.checkout?.shippingAddress?.city,
      region: event.data?.checkout?.shippingAddress?.province,
      postal_code: event.data?.checkout?.shippingAddress?.zip,
      provinceCode: event.data?.checkout?.shippingAddress?.provinceCode,
      country: event.data?.checkout?.shippingAddress?.country,
      countryCode: event.data?.checkout?.shippingAddress?.countryCode,
    }
  });

  gtag('event', 'conversion', {
    send_to: 'AW-123456789/abcdefg123456789',
    transaction_id: event.data?.checkout?.order?.id,
    value: event.data?.checkout?.subtotalPrice?.amount,
    currency: event.data?.checkout?.subtotalPrice?.currencyCode,
  });
});

From your previously copied code from Google Ads, copy the AW-123456789 id highlighted in the image below.

And paste it twice on row 3, and row 10, by replacing the existing ID AW-123456789 (shown in red in the image above)

Go back to your Google Ads code and now copy the full ID and Label as highlighted in the image below.

Replace the send_to value between the quotes on row 14. (shown in red in the above image)

Now click on save in the top right corner followed by clicking on Connect, accept Shopify terms and conditions. And you are all done.

Testing

You can’t test code on Shopify’s checkout thank you page because it’s in sandbox mode, meaning tools like Google Tag Assistant or GTM Preview Mode won’t work. While you could use console.log to check data, I think it’s unnecessary effort. The code does work. Simply wait for a sale to confirm that it’s tracked in Google Ads as a conversion when it comes from an ad click or wait until you have any sale, Google Ads will show the code is detected.

Change Log

• V1.05 – 20 May 2024: Changed the order of gtags
• V1.04 – 20 May 2024: Added user_data values after Sve (comment below) confirmed Google’s own version. I already built this months ago, but needed confirmation it’s correct.
• V1.03 – 02 March 2024 : Supports multicurrency and used subtotal price instead of total
• V1.02 – 27 February 2024 : Public Release

Support My Work!

My conversion tracking code is constantly updated and provided free for anyone to use. As I don’t ask for any monitary value in return, I would be grateful if you consider leaving a review: https://www.trustpilot.com/review/feedarmy.com

Supported Functions

• Automatically supports multi currencies.
• Automatically converts European prices with commas to dots.
• Optional choice for disabling tax and shipping in your checkout value.
• Includes the new Google Ads enhanced conversion option

Requirements

• Access to Google Ads > Conversions
• Access to Shopify > Settings

Step 1: Open Shopify Checkout Settings

Open a new tab in your browser and log in to your Shopify Admin Panel

Navigate to Settings (Gear Icon) and choose Checkout

Step 2: Setup & Copy Your Google Ads Conversion Code

In a second browser tab, login to Google Ads and click on the tools and settings menu in the top right corner and select Conversions under the Measurement column.

Click on the big blue plus sign (New Conversion Action).

Now select website as your tracking template.

It will now ask you to scan your website URL. Enter your URL and click on scan.

Scroll to the bottom and choose to install the conversion action manually.

Then do the following :

• Conversion name
  • enter any name
• Category
  • Purchase / Sale
• Value
  • Use different values for each conversion
• Attribution model
  • Choose Position-Based (recommended for growth based businesses)
• The rest can be as default

I have written a great article on how to choose your attribution model.

Click on Create and continue

Now you can click on Save And Continue

Click on See Event Tag

Copy your Event Snippet and save it in a temporary file, for later use.

Click on Done

Click on the recently added conversion action

Enabling Enhanced Conversions is optional and not required. Some accounts may not see this option yet. So you can continue the steps below, excluding those related to enhanced conversions. (Skip to Step 3)

Now go to Tools and Settings > conversions > settings or click here: https://ads.google.com/aw/conversions/customersettings

By enabling enhanced conversions you allow Google to improve its accuracy to track conversions. This seems to be required due to Apple’s IOS14 no tracking prompt.

After you have checked the box and clicked on save, you will get a terms and conditions prompt, read it and confirm.

Now choose Google Tag and click on Tag Details.

Now check the box next to Specify CSS selectors or JavaScript variables

• Change CSS selector to Global Javascript variable
• Enter the following values for Email
  • enhanced_conversion_data.email

Repeat the steps for Phone number and Name and Address

• Phone
  • enhanced_conversion_data.phone_number
• First name
  • enhanced_conversion_data.first_name
• Last name
  • enhanced_conversion_data.last_name
• Street address
  • enhanced_conversion_data.home_address.street
• City
  • enhanced_conversion_data.home_address.city
• State
  • enhanced_conversion_data.home_address.region
• Country
  • enhanced_conversion_data.home_address.country
• Postal code
  • enhanced_conversion_data.home_address.postal_code

You might ask, why the javascript values? Well on your thank you page, the javascript selector for all the values is added as a javascript variable when using the conversion tracking code below (From V1.5). This will only work if you use the code below.

Step 3: Editing and Pasting Your Google Ads Conversion Tracking

Go back to Shopify and scroll down until you see Order Processing (from step 1), at the bottom of this section you will have a field where you can paste code that is labeled Additional Scripts.

If you have two fields such as post purchase and order status, then add the code to the order status field.

Copy the send_to value (image below) and replace fa_send_to value with your value in the code template below.

1. replace the value for fa_send_to
   • replace the value AW-123456789/abcdefghijlklmnopq with your event snippet send_to value
2. Choose yes or no for fa_include_tax_and_shipping
   • choose yes if you want to include tax and shipping in the checkout value or no to not include tax and shipping values.

Sometimes on rare occasions, when you set fa_include_tax_and_shipping to no, it would still include the shipping. I’m not sure why this sometimes happens, but it might have to do with the account country. So if you notice shipping is included, set the value to yes, and it will remove shipping.

Verifying and Testing

Verifying

You can verify if the code is working if you go to Google Ads > Tools and Settings > Conversions > here check if the status is verified.

Testing

First open up Tag Assistant when the new window opens up make a test payment to check if the conversion tracking is correctly installed. When you are on the final thank you page check the data within Tag Assistant.

Tip:
first_time_accessed is for the page, not for the customer. Subsequent orders will run a first_time_access again for the same person if it is a new browser session.

Trouble Shooting Enhanced Conversions

Make sure you have waited at least 3 to 7 days. Google requires time to compile the data.

Coverage:

You may encounter issues with regard to coverage. This can happen when customers pay through a third-party payment processor (PayPal), which may require that they enter customer data on a different domain instead of directly on your website like they do when they do not use a third-party payment processor. 

Match status:

If you are having issues with the match status, not all users fill out all the fields in your checkout. What you could do is remove the attributes in your Google Ads conversion list to only track emails or only track mandatory fields in your checkout.

By removing non-mandatory fields, you will avoid submitting empty fields to Google.
