10 common Shopify → Google Shopping feed errors (and how to fix each)

Shopify's product data doesn't always line up with what Google Merchant Center demands. These ten mismatches cause the vast majority of disapprovals — here's the fix for each.

1. Invalid GTIN check digit

A mistyped barcode fails Google's check-digit test. Fix: correct it, or set identifier_exists = no — never invent one. Full guide.

2. No identifier and identifier_exists not set

Own-brand items with no GTIN/MPN still need identifier_exists = no. Fix: add that field for unbranded products.

3. Price format / currency

Google wants 24.99 GBP, not £24.99 or 24,99. Fix: number + ISO currency code, dot decimal.

4. Availability value not recognised

available / in stock / yes are rejected. Fix: use in_stock, out_of_stock, preorder, or backorder.

5. Missing image_link

No image, or a broken/placeholder image URL. Fix: a valid https:// product image, no watermarks or promo text.

6. Promotional text in the title

"Free shipping", "Sale", "Best price" in titles get flagged. Fix: describe the product, don't advertise it.

7. ALL-CAPS titles

Fully capitalised titles are a classic trigger. Fix: normal title case.

8. Title over 150 characters

Long titles get truncated or penalised. Fix: trim to ≤150, front-load key words.

9. Missing description

Empty descriptions (common when Shopify body HTML is blank) disapprove items. Fix: add a real description, no promo text.

10. Missing id or link

Every product needs a unique id and a valid landing-page link. Fix: ensure both are present and unique.
