    Your Products Aren't Showing — Here's Why

    Nothing's more frustrating than logging into Merchant Centre and seeing a wall of red warnings. Products disapproved. Limited visibility. Account suspended.

    I've seen it happen to hundreds of UK ecommerce stores. Here are the five most common culprits — and exactly how to fix them.

    Error 1: Price Mismatch

    The problem: Your feed price doesn't match your website price.

    Why it happens: Manual feed uploads, currency issues, or sales/discounts not syncing.

    The fix: Use a real-time feed solution (Simprosys, DataFeedWatch, or native Shopify/WooCommerce plugins) that automatically updates prices.

    Error 2: Missing or Invalid GTINs

    The problem: Google requires GTINs (EAN/UPC codes) for most branded products.

    Why it happens: Suppliers don't provide them, or they're entered incorrectly.

    The fix:

    • Request GTINs from your supplier
    • For custom/handmade products, set identifier_exists to "no"
    • Double-check formatting (13 digits for EAN)

    Error 3: Image Issues

    The problem: Images don't meet Google's requirements.

    Common issues:

    • Promotional text on images
    • Too small (under 100x100)
    • Stock photos not showing actual product

    The fix: Use clean, high-resolution product photos on white backgrounds.

    Error 4: Missing Shipping Settings

    The problem: You haven't configured UK shipping in Merchant Centre.

    The fix: Go to Shipping and returns > Add shipping service. Set your UK rates and estimated delivery times.

    Error 5: Policy Violations

    The problem: Products violate Google's policies (even unintentionally).

    Common triggers:

    • Health claims on supplements
    • Missing required information (ingredients, materials)
    • Counterfeit concerns

    The fix: Review Google's policies for your product category. Add required attributes.
