Inconsistent language between the feed and the website
What causes the "Inconsistent language between the feed and the website" error in Merchant Center and how to fix it.
This error means the language your feed is declared in doesn't match the actual language of your landing pages or checkout. Fix it by aligning the feed's language setting with the real site language, or submitting a separate feed per language or market.
What triggers it
"Inconsistent language between the feed and the website" means Google has compared the language your feed is submitted in (or declared for) against the actual language of the landing pages and checkout flow, and found them to disagree. This usually surfaces after a site adds a new market or language without setting up a matching feed, or when one feed is reused across several country targets that don't all share a language.
It's a trust signal as much as a technical one: Google wants the shopping experience to genuinely match what the feed promises, so a French feed pointing at English-only pages fails this check even if every other attribute is correct.
/tools writes enriched copy consistent with the feed's configured language on a supplemental layer, which helps keep multi-market setups aligned rather than drifting as new languages or storefronts get added.
Step by step
- Check the language your feed is declared under. Confirm the language setting configured for the feed or target in Merchant Center matches the language your product data is actually written in.
- Check the actual language of the landing page and checkout. Google compares the feed's declared language against the live page a shopper lands on and checks out through, not just the product title and description text.
- Align the feed's declared language with the real site language. If a store serves multiple languages, correct the mismatch for the affected feed rather than assuming one setting covers every market.
- Submit a separate feed per language or market if needed. Where a site genuinely serves more than one language, a dedicated feed per language keeps the declared language and page content consistent for each.
- Re-submit and confirm the flag clears. Once the languages match and Google re-fetches the feed, the error should clear within the normal crawl window.
