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.

Trouble Shooting

Can Not See Data Layers

Because Shopify pixels run in sandbox mode, for privacy reasons, you cannot view data layers in your browser using conventional tools.

You will need to use a Chrome extension such as https://chromewebstore.google.com/detail/datalayer-checker-plus/blglfmihmnbhfgfbomofeljmididgfhe

Even then, it is only sometimes 100% working.

Zero Tracking

If nothing is working, even adding to the cart, that signals more serious issues. This means there is possibly a third-party app blocking pixels from working.

It’s also possible that your cookie consent is not enabling tracking, you can test by forcing the consent to be set as accurate in the code settings.

Some Conversions Are Tracking

If you notice that not all conversions are tracked in Google Ads, this signals that the payment method you are using is not sending back the correct data to Shopify. This is a known issue with third-party payment methods, even with the old additional script method.

Conversion Not Working

If your conversions are not working, then most likely your theme checkout and thank you page are not published.

Go to Shopify > Online Store > Themes > Click on Customize

Click on the home page drop down and select Checkout and new customer accounts

Click on checkout drop down and choose thank you and or checkout (whichever says unpublished)

Click on the sections button and publish.

You can also check if your checkout domain matches your domain. In some cases the domain name is myshopify.com instead of your domain.

Google Analytics Average Engagement Time Per Session

When using Shopify Pixels / Customer Events, and due to Shopify using sandbox environment, automatic events, including engagement event for Google Analytics aren’t triggered.

Version 3 includes everything from Version 2, plus full local inventory feed support for Google Merchant Center.

You can get the code here. Begin by adding the code to Shopify, then follow the Version 2 steps before updating your local settings as shown below.

Local Settings Setup

Add your local configuration values in the pixel code:

const LOCAL_TARGET_COUNTRY_CODE = 'US';   // ISO2 country code (e.g. "GB" for United Kingdom)
const LOCAL_LANGUAGE = 'en';              // Alpha-2 language code (e.g. "de" for German)
const LOCAL_STORE_CODE = '1234';          // Google Business Profile store code

• Country Code (ISO2): If unsure, search online (example: United Kingdom ISO2 code = GB).
• Language Code (Alpha-2): Again, search online if needed (example: Germany alpha2 code = de).
• Store Code: Your Google Business Profile store code.

Upgrading from Version 2

• If you are already using Version 2, upgrade to Version 3 by importing the V3 update file in Google Tag Manager.
• If you have never installed FeedArmy tracking before, follow the Version 2 tutorial first. Once complete, continue with the V3 setup.

Be sure to save your Shopify pixel once all changes are applied.

Once installed and you have waited 2 days, fill out this form: https://support.google.com/merchants/contact/website_reported_product_feeds#

This Shopify Pixel / Customer Event code, has been tested and verified as working for Shopify merchants that have enabled Checkout Extensibility.

The first step is to get your conversion id and label.

Log in to Google Ads and go to Goals > Conversions > Summery

Click on the blue button that says + New conversion action

Select Website as your conversion method.

Enter your website address, and scan.

If you see a banner that says to use Google Analytics, then click on Use Google Ads only

Click on +Add conversion action manually.

• Choose Purchase as your Goal and action optimization
• Enter any conversion name, I will call it Shopify Pixel
• Select Use different values for each conversion
• Leave the rest unchanged and click on done

Click on See event snippet

Copy the code and paste in a temporary text file, we will copy some details at a later stage.

Click on Done.

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. If you want to check data layers, you need to use a chrome extension such as https://chromewebstore.google.com/detail/datalayer-checker-plus/blglfmihmnbhfgfbomofeljmididgfhe
