10 Common Google Merchant Center Errors and How to Fix Them

Getting your products live on Google Shopping shouldn't feel like solving a puzzle. Yet many merchants struggle with feed errors that prevent their products from appearing in search results. Let's fix the 10 most common issues.

1. Missing or Invalid GTIN

Error: "Missing value [gtin]"

Fix: Add valid GTINs (barcodes) for all branded products. If you manufacture your own products, apply for brand exemption in GMC. For non-branded items, use the identifier_exists attribute set to FALSE.

2. Price Mismatch

Error: "Price mismatch"

Fix: Ensure your feed price exactly matches your landing page price, including currency and sale prices. Use MeshFeed's automatic sync to prevent this common issue.

3. Incorrect Availability

Error: "Availability: out of stock"

Fix: Only feed products that are actually in stock. Update your feed within 24 hours when inventory changes. Automate this with scheduled syncs or on-demand refreshes to avoid manual updates.

4. Poor Image Quality

Error: "Image link: image quality issue"

Fix: Use images that are at least 800x800 pixels. Ensure white or transparent backgrounds for apparel. Use MeshMedia's AI enhancement to automatically improve image quality.

5. Invalid Landing Page

Error: "Landing page not working"

Fix: Verify all product URLs are live and load quickly. Check for SSL certificates (HTTPS), mobile compatibility, and that pages match the products in your feed.

6. Prohibited Content

Error: "Policy violation: prohibited content"

Fix: Remove products that violate Google's policies (weapons, dangerous items, adult content). Review Google's Shopping Ads policies regularly.

7. Missing Product Identifiers

Error: "Missing [brand] or [mpn]"

Fix: Include brand names and manufacturer part numbers (MPN) for all products. These are required for most categories to improve matching accuracy.

8. Incorrect Product Category

Error: "Invalid [google_product_category]"

Fix: Use Google's product taxonomy. Assign the most specific category that matches your product. MeshList's AI can automatically suggest correct categories.

9. Mismatched Product Titles

Error: "Title doesn't match landing page"

Fix: Ensure feed titles closely match your landing page titles. Include brand, product type, and key attributes. Keep titles under 150 characters.

10. Invalid Shipping Data

Error: "Invalid [shipping]"

Fix: Configure shipping costs in GMC settings or provide accurate shipping data in your feed. Include all required countries and specify costs clearly.
