Cart Data Fixes for Google Ads Conversion Tracking

Many Shopify stores using Google Ads have encountered two persistent conversion tracking warnings: "Many recent conversions have cart data with formatting issues" and "Many recent conversions don't have cart data." This release addresses the root causes behind both.

What It Means

These warnings were triggered by a combination of data formatting and validation issues across purchase events, remarketing fields, and product ID handling.

No single fix resolved them — instead, this update addresses multiple underlying causes together.

Key changes include:

corrected cart data formatting in purchase and checkout events
proper inclusion of shipping and tax values (even when zero),
resolved product ID inconsistencies that caused feed lookup failures,

and fixes to how discount values and remarketing fields were handled across conversion events.

Improvements +

Feed language is no longer incorrectly required for Dynamic Remarketing validation — stores without a configured feed language will no longer have events blocked
Shipping and tax values of zero are now properly included in purchase and checkout events
Globally configured user data is no longer unintentionally overridden by partial event-level data, improving enhanced conversion matching
Business vertical field for Google Dynamic Remarketing now uses the correct value
Ad personalization signals now correctly respect the pixel's configured scope
Duplicate page_view hits no longer fire when the Google tag was already initialized by another integration
Fixed a crash that could occur when carts did not contain discount codes

How It Helps +

This update helps you:

Eliminate the two most commonly reported Google Ads conversion warnings related to cart data
Improve the accuracy of your reported ROAS and discount figures
Ensure enhanced conversion matching works reliably without user data being unintentionally overridden
Maintain cleaner conversion data by preventing remarketing fields from appearing where they don't belong

These warnings have already been eliminated for several stores following this update. No configuration changes are needed.
