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.

Frequently asked questions

What are the most common Google Merchant Center errors?

The most common issues are missing or invalid GTINs, price mismatches between the feed and landing page, incorrect availability, poor image quality, invalid landing pages, prohibited content, missing brand or MPN identifiers, incorrect product categories, mismatched titles, and invalid shipping data. Each of these can stop affected products from showing on Google Shopping until it is fixed.

How do I fix a price mismatch error in Google Merchant Center?

Make sure the price in your feed exactly matches the price on your landing page, including currency and any sale prices. Keeping your feed automatically in sync with your store, for example with MeshFeed's automatic sync, prevents this error from recurring.

Why are my products showing as out of stock on Google?

Availability errors usually mean your feed is sending stock data that no longer matches your store. Only feed products that are actually in stock and update your feed within 24 hours when inventory changes, using scheduled syncs or on-demand refreshes to avoid manual updates.
