Google Merchant Center: Missing google_product_category
Missing required attribute: google_product_categoryWhat's happening
google_product_category is optional, Google auto-classifies products that omit it, but leaving it to the algorithm is a gamble. A mis-classified product competes in the wrong auctions and can miss category-specific features. Setting it explicitly fixes the classification and is effectively required to compete well in apparel and electronics, where the auto-guess is often wrong. (It is NOT a hard ingest requirement; verified 2026-06.)
google_product_categoryproduct_typeManual fix
Look up each product's correct category in Google's taxonomy (https://support.google.com/merchants/answer/6324436), enter into CMS, export.
Fix it with Emberfeed
Use a conditional field rule keyed off your existing product_type or category field. e.g. if g:product_type starts with "Clothing" → set g:google_product_category to "Apparel & Accessories > Clothing". One mapping rule replaces hours of per-product work.

Emberfeed checks every product against Google Merchant Center's required fields and format rules, and most problems come with a fix: a field rule for the whole feed or an override for one product. It also measures your product photos, while rendering them and in the background after each refresh, and flags the ones that are too small for Google Merchant Center.
Emberfeed is a hosted tool: it imports your existing product feed, renders every product image through one template and serves a new feed URL for Meta, Google, TikTok, Heureka, Zboží.cz and Glami. It costs 25 € per feed per month, and the first 3 months are free on one feed up to 1,000 products.
