The Product Feed Validation Checklist: What to Verify Before You Publish

Run through this before you consider product feed validation actually done:

1. Validate after every feed regeneration, not just the first submission — schema drift creeps in silently as your product catalog or CMS changes.
2. Check character limits per field (150 for title, 5000 for description) — feeds that pass locally can still get truncated or rejected if a plugin adds unexpected length.
3. Confirm GTIN/MPN formatting matches the required pattern for your product category — malformed identifiers are a very common, easy-to-miss rejection reason.
4. Validate currency and price formatting per target country if you're running multi-region feeds — a comma-vs-period decimal mismatch alone can invalidate every row.
5. Double-check this after any site migration or major redesign, not just at launch.

None of these individually take long. The value is in doing all of them, every time, instead of remembering most of them most of the time.

Pair this with the GTIN validation checklist if you're doing a fuller pre-launch pass.
