New Google Ads diagnostics tool for cart data tracking is here

 

Google's new tool flags mismatched or incomplete cart data that could distort sales reporting and weaken campaign optimization.

Google Ads rolled out a diagnostics tool to help advertisers spot issues with shopping cart data tied to conversions.

The tool appeared in accounts, following an initial mention on a Google help page last week.

Advertisers can access it by hovering over the Status column for a specific conversion action.

How it works. A pop-up dashboard surfaces key checks:

• Conversions recorded.
• Enhanced conversions active.
• Consent mode active.
• Shopping cart data match issues are flagged in red when item IDs or details don’t align with Merchant Center.

Google’s tool evaluates whether:

• Cart data is sent with each purchase.
• Product details are complete.
• Item IDs match those in Merchant Center.

Why we care. Clean cart data helps Google optimize campaigns and improve reporting. If item IDs or product details don’t match, Google can’t properly attribute revenue or calculate return on ad spend, leading to wasted budget and misleading reports. This tool gives advertisers visibility into those data gaps, helping them fix tracking issues before they hurt performance.

Bottom line. Google is shining a spotlight on cart data quality, giving advertisers new visibility into mismatches that could undermine Shopping and Performance Max campaign performance
