Shopify products not syncing to Google Merchant Center

Merchants routinely report catalogs where half the SKUs never appear in GMC — with no error in Shopify. Common causes: not published to the Google & YouTube channel, invalid barcodes, missing required apparel attributes, or dual data sources (Content API + website crawl) fighting over IDs.

Checklist

• Filter products by Google & YouTube availability.
• Validate barcodes (check digit) and brand/MPN pairs.
• For clothing/shoes: gender, age_group, color, size.
• Confirm a single primary data source in Merchant Center.
