# Google Merchant Center Feed Errors on Shopify
Feed errors occur when the product data sent from your Shopify store to Google Merchant Center is structurally invalid or missing required attributes. This prevents Google from processing the products entirely.

## Fix Process
1. **Identify the Error:** Check the "Processing" tab in the Merchant Center Feeds section.
2. **Missing GTIN/Brand:** Ensure the Shopify Barcode field is populated. If the item has no barcode, set `identifier_exists` to false in your feed app.
3. **Price/Availability Mismatch:** Use a feed app that syncs frequently or in real-time, and enable Automatic Item Updates in Merchant Center.
4. **Invalid Formatting:** Ensure descriptions contain no HTML tags and titles are under 150 characters.
