Google has updated its language policy in Google Merchant Center, permitting some inconsistencies between the product feed language and the website language. Starting December 2024, product information such as title, description, and variant details can be in a different language, provided that most of the product data aligns with the feed language.
However, this may lead to reduced performance on Google Shopping, as the information may not match user search terms. It's also mandatory for checkout elements to be in the same language as the product feed to ensure a coherent user experience.
