Reading Google Merchant feed diagnostics without guesswork

A feed can fail because the file cannot be parsed, because a required attribute is absent, or because a product value conflicts with policy or landing-page data. Those categories need different fixes.

Start with errors that prevent parsing, then required identifiers and attributes, followed by price and availability consistency. Warnings can be reviewed after the blocking set is stable.

GTIN, MPN, brand, and identifier-exists describe real product identity. Formatting a valid identifier is appropriate; inventing one is not. If a product genuinely lacks standard identifiers, represent that condition according to the destination rules.

Price, currency, condition, availability, and product identity should agree with the destination page. A perfectly formatted feed can still be rejected when the page presents a different fact.

Use timestamps and scheduled fetches deliberately. A stale feed and a recently changed storefront can create a temporary mismatch that looks like a formatting error.

Validate the feed structure, normalize safe deterministic values, isolate identity questions for human review, then verify a sample against live landing pages. This keeps automated fixes away from business facts they cannot infer.
