Forty percent of shoppers won’t buy in a foreign language, and machine translation doesn’t fix that
That figure from CSA Research sets the stakes clearly: poor localisation is not a minor inconvenience, it is a conversion blocker. Yet the reflex among many cross-border merchants is to enable platform-level auto-translation and call it done. The article from Practical Ecommerce, written by a native Polish copywriter operating inside the EU market, explains precisely why that falls short.
The problem is credibility, not comprehension. A machine-translated product page can be grammatically correct and still feel foreign enough to trigger doubt. In cross-border shopping, where trust is already fragile, that doubt tends to resolve in favour of abandonment rather than purchase. The checkout itself is especially exposed: transactional copy, error messages, field labels, and confirmation language all carry trust signals that a literal translation flattens.
The piece makes a distinction worth holding onto. Translation gives you the meaning; localisation gives you the idiom. “Your new go-to jacket” becomes stilted in German the moment you translate it word for word. A local copywriter rewrites the promise rather than the sentence. The same principle applies to checkout microcopy: the label on a submit button, the wording of a returns notice, or the tone of a payment-declined message can feel either native or suspicious depending on how much adaptation went in.
Beyond copy, the article flags fields and formats that need local treatment regardless of language quality: address structures, date formats, currency display, and payment method availability. A German shopper who reads fluent German on your product page but then hits a checkout built for another market has already received a signal that you don’t really operate here. Conversion data from cross-border transactions consistently shows higher drop-off at exactly this point in the funnel.
Only 20% of Germans and 13% of Poles bought cross-border within the EU in 2024. Language is one barrier, but the checkout experience is where language failure becomes revenue failure. Running a human review of your checkout copy in each target locale, and treating payment options and address fields as localisation tasks rather than technical afterthoughts, is where the gap between auto-translate and actual conversion closes.
