On my Google ads campaign page, the “Units sold” column is always blank, even though I am getting lots of conversions with my ads. What do I need to change in my Shopify code so that “Units sold” is passed on to Google with every conversion?

Hi @PWS1

To ensure the “Units sold” column is populated in Google Ads, you need to properly configure your Shopify store to send the required conversion data to Google Ads. Follow these steps:

1-Enable Enhanced Conversion Tracking:

  • Go to your Google Ads account.
  • Navigate to Tools & Settings > Measurement > Conversions.
  • Ensure that Enhanced Conversions is enabled and properly set up.

2-Update Shopify Code:

  • Add the Google Ads conversion tracking tag to your Shopify checkout settings.
  • Use Google Tag Manager to capture and pass transaction_id, value, and items for every conversion. Ensure the data layer includes the quantity of items sold.

3-Verify Event Data:

  • Ensure the purchase event in Shopify includes the correct quantity and item details.
  • Test using Google Tag Assistant or Google Ads Conversion Diagnostics to confirm data is being sent correctly.

4-Sync Product Data with Google Ads:

  • In your Shopify Google channel, ensure all products are synced with correct attributes, including SKU and quantity.

By ensuring the tracking code and enhanced conversion settings are correct, the “Units sold” data will populate in your Google Ads campaign.
