Google Merchant Center
Every entry explains what Google is actually rejecting, why your platform produces the problem, the manual fix, and the IRONFEED rule that resolves it across the whole catalog.
- Missing value [gtin]
- Invalid value [gtin]

Meta Commerce Manager
Each guide covers what Commerce Manager rejects, why your store export produces it, the manual fix, and the IRONFEED rule that applies it to every product.
- Universal product code or availability is missing
- Pixel and catalog price/currency mismatch
