How to Fix Variant Group Consistency Errors

Review item_group_id families and duplicated identifiers in merchant feeds.

How to diagnose and repair the issue

  1. Check for duplicated product IDs
  2. Inspect each family item_group_id
  3. Verify variants share a real product family
  4. Compare brand and product type within the family
  5. Correct unrelated grouping and validate again
⚠ Before exporting

A single-row variant group is a review flag, not an automatic platform rejection.

Check the fix

Keep an untouched copy of your source feed. Run the relevant check again, inspect flagged rows and compare a small sample with your store catalog. Merchant Center may apply additional requirements by country, product category and destination.

For the definitive requirements, review Google's current product data specification and your own Merchant Center diagnostics.
