In short. Add a product source for each supported language, select the same target country, and match product pages and checkout to the submitted language and currency.
Definition: A product data source, also called a feed, supplies product information to Google Merchant Center. As of 17 October 2026, Google's additional-language instructions describe creating another data source for each language, with the same target country selected and translated product pages.
Key facts
- Google's supported languages and currencies documentation allows a data source in any supported language, including English and French, for countries where Shopping ads and free listings are available.
- Google's additional-language workflow includes selecting countries and a language when adding a product source.
- Google's landing page requirements require the destination product page to use the product data's language, including in multilingual countries.
- Google's checkout requirements extend language consistency to the shopping cart, terms and conditions, return policy and contact information.
How is another language added for the same country?
Google's instructions for additional languages give this Merchant Center menu path:
Settings > Data sources > Product sources > Add product source
The pencil icon opens the country selection. The existing target country is selected again, followed by Save. The Language dropdown sets the language of the new source; Continue advances the setup. The translated products take effect upon the next upload to that source.
The same documentation requires shipping settings to cover the selected country. For Shopping ads, Google Ads location targeting must also match the Merchant Center target country.
What must match on the website?
A landing page is the destination reached through a product link. Google's landing page requirements identify the link attribute as the default product destination. Each language source therefore needs links to matching product pages. Google's example explicitly rules out English product data leading to a French page for Canada.
The same requirements cover the title, description and variant information. Product details must refer to the same product or variant, and the displayed price and currency must match the submitted data.
Google's checkout guidance requires the source language throughout the purchase process. Its relevant pages include the cart, checkout, terms and conditions, refund and return policy, and the About page with contact details.
Does changing language require changing currency?
Google's supported languages and currencies documentation treats language selection and currency requirements separately. A supported language can address a language group within a country even when it is not a major language there.
For submissions using the target country's currency, shipping information uses the same currency as product prices. The website also displays costs in that currency.

FAQ
Can I use a language that is not a country's main language?
Yes. Google's language documentation permits supported languages for specific language groups within a target country.
Can I keep checkout in a different language?
Google's checkout requirements require you to maintain the product data source's language throughout checkout. A mismatch can cause product disapproval.
