Feed Quality Control
With the Quality Control tool, you can identify and fix issues in your product feed before uploading it to sales channels.
Mulwi flags feed problems that could prevent your products from being listed, helping you quickly resolve them and optimize your feed for best results.
Types of Quality Control issues
Mulwi's Quality Control detects three types of issues:
| Issue status | Description | Examples |
|---|---|---|
| Errors | Critical issues that you absolutely must resolve, otherwise your products will be rejected | Missing required attributes, duplicate unique values, invalid data (title too long, wrong price format, etc.) |
| Warnings | Important issues that won't prevent listing but may affect product visibility or performance | Missing recommended attributes, duplicate product titles |
| Improvements | Suggestions that will help you optimize your feed for the best results | Product title optimization, enhanced attribute data format, adding optional attributes |
When you run a Quality Control scan, Mulwi provides the breakdown of all errors, warnings, and improvements for each of the feed's product separately.
