In monitoring, a changed report triggers a service email linking to your dashboard. This example sends no email. A change is not proof of lost sales or a Google listing problem.

No. This checks a defined subset of product-data rules. It does not check store policies, images, landing-page matches, shipping, tax, country-specific requirements or account status. Google’s own diagnostics remain authoritative.
The free checker processes your file in your browser. It does not send the feed to our servers or an AI model. If you later subscribe to monitoring, the service must fetch and process your configured feed.
You can check an export before submission and share a focused list of formatting issues with whoever maintains the feed. Monitoring is intended to add an independent history, not replace Merchant Center.
Some requirements depend on your product type or market. We flag those for checking rather than claim they are definitely errors.
