Issue Dictionary

Plain-English guides for Shopify, Google Merchant Center errors, feed warnings, product data gaps, and ad fix best practices.

Merchant Center issues are easy to cause. A missing GTIN, use of a disallowed image, or mistyped attribute can affect product visibility across Google Shopping, free listings, YouTube, Search, and other Google surfaces.

FeedRescue AI turns MC error signals into actionable fixes. We show what each error means, how to check a mismatch, and when a low repair alert flag like batch or surcharge product data.
