How to Setup Google Ads Conversion Tracking in Shopify

To set up conversion tracking in Shopify, the following tags are required.

1. The Global Site Tag
2. An Event Snippet

If you have not yet set up a conversion in Google Ads yet, please visit How to Create a New Conversion in Google Ads, for the instructions on how to add a conversion.

If you already have a conversion setup in Google Ads that you would like to track, you can follow the instructions below:

1. Sign into Google Ads
2. In the upper right corner, click the tools icon , and under “Measurement,” click Conversions.
3. Select the conversion you would like to track.
4. Below “Settings” there is an option for “Tag Setup”. Expand that window.

5. Under “Tag setup” select “Install the tag yourself”
6. Under “Global site tag”;

7. Copy your “Global site tag”. *Note* the account number below should be different for your tag.

<!-- Global site tag (gtag.js) - Google Ads: 1010101010 -->
<script async src="https://www.googletagmanager.com/gtag/js?id=AW-1010101010"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());
  gtag('config', 'AW-1010101010');
</script>

11. Open your checkout.liquid file.

<!-- Event snippet for Transaction conversion page -->
<script>
  gtag('event', 'conversion', {
      'send_to': 'AW-1010101010/xxxxxx_xxxxxxxxxxxx',
      'value': 1.0,
      'currency': 'USD',
      'transaction_id': ''
  });
</script>

a. On the line before the snippet, paste:

{% if first_time_accessed %}

b. On the line after the snippet, paste:

{% endif %}

19. The default currency is USD. If you don’t sell in US dollars or want to match the currency with your Shopify site, replace ‘USD’ in the event snippet with '{{ currency }}'
20. The default transaction ID is blank. To prevent Google Ads from recording duplicate conversions, next to ‘transaction_id’: replace ” with '{{ order_number }}
21. In order to make your conversion value dynamic, replace the line beginning with ‘value’: with one of the following snippets:

{% if first_time_accessed %}
<!-- Event snippet for Transaction conversion page -->
<script>
  gtag('event', 'conversion', {
      'send_to': 'AW-1010101010/xxxxxx_xxxxxxxxxxxx',
      'value': {{ checkout.subtotal_price | money_without_currency }},
      'currency': '{{ shop.currency }}',
      'transaction_id': '{{ order_number  }}'
  });
</script>
{% endif %}
