You sell in more than one market, or your product spread by word of mouth into one, and now you have a wonderful problem: a customer sent you a testimonial in a language most of your buyers do not read. It is specific, enthusiastic, and exactly the kind of proof your landing page is missing — except the page is in English and the quote is in German.
The lazy move is to run it through a machine translator, paste the output under an English name, and move on. The careful move takes ten more minutes and protects two things at once: whether prospects believe the quote, and whether you can defend it if the customer ever sees how you rendered their words. Here is how to decide what to do with a foreign-language testimonial.
First, decide whether to translate it at all
Not every foreign-language testimonial should be translated. Three situations change the answer.
- Your prospect actually reads the language. If the testimonial is aimed at a market that speaks it — a German quote on your German pricing page — leave it alone. Translating a native-language quote out of its own market strips the credibility you were trying to add.
- The customer's name signals the market. A quote from "Müller GmbH, Munich" reads as authentic precisely because it is in German next to a German company. On an English page, that same authenticity can survive if you present the original and the translation together, rather than replacing one with the other.
- The quote leans on an idiom that will not survive. Some praise is carried entirely by a phrase that has no clean English equivalent. If the punch is the idiom, a literal translation lands flat, and you are better off choosing a different testimonial than shipping a dead one.
If none of those apply and your prospects genuinely cannot read the original, translate — but translate it as a quote, not as a sentence.
Translate meaning, not words
A testimonial is a claim a real person is willing to stand behind. That raises the bar above ordinary translation. Two rules keep you honest.
- Do not upgrade the enthusiasm. Machine and eager human translators both tend to inflate. "It works well for us" should not become "It's transformed our entire business." You are not allowed to make the customer sound more excited than they were — that is putting words in their mouth, and if they read it back, you have burned the relationship and your credibility in one move.
- Do not launder away the hedges. If the original said "after a rough start, it became indispensable," keep the rough start. Translations that quietly delete the qualifier produce the suspiciously uniform praise buyers have learned to distrust. The hedge is often what makes the quote believable.
When a claim is ambiguous in the original, the safest path is to ask the customer which reading they meant — which conveniently doubles as a permission touchpoint, covered below.
Show your work: original plus translation
The most credible way to display a translated testimonial is to show both. Put the translated quote in your prospect's language as the headline, and include the original underneath in smaller type, with a short label like Translated from German. This does three things a bare translation cannot:
- It signals honesty. You are not hiding the fact that this quote was translated, which reads as confident rather than evasive.
- It survives scrutiny. A bilingual prospect — or the customer themselves — can check your work. Anyone willing to show the original is telling you the translation is faithful.
- It keeps the geographic proof. The original language, next to a real company and city, is itself a credibility signal that says this product works in markets beyond this page. That is worth more than a clean but rootless English sentence.
If space is tight, a single line — "Translated from the original German" — under the attribution does most of the work. The point is to disclose, not to conceal.
Get permission for the translation, not just the quote
Here is the step almost everyone skips. The customer approved their words in their language. They did not approve your English rendering, and a translation is an interpretation you are attributing to them. Before you publish, send the customer the translated version and ask them to confirm it says what they meant. Most will reply in a sentence. Some will correct a nuance you would never have caught — and that correction is worth more than the ten minutes it costs.
This is the same discipline you apply to any edited quote: the customer signs off on the final published form, not just the raw one. If you already run a lightweight approval step when you draft a testimonial for a customer to approve, the translation simply becomes part of what they approve. And because you are already collecting the name, title, and company permission you need to attribute the quote at all, folding the translation into that request costs you no extra round-trip.
When you genuinely cannot translate it well
Sometimes the best answer is to not use that particular quote on that particular page. If the testimonial's power is inseparable from an idiom, or the customer is unreachable to approve a translation, do not force it. A faithful, boring quote you can stand behind beats a vivid one you had to invent. Keep the original on the market page where it belongs, and find a different quote for the page whose language it does not fit.
The short version
A foreign-language testimonial is real proof you have to handle with care, not a raw asset to run through a translator. Decide whether translation even helps, translate the meaning without inflating or laundering it, show the original alongside the translation, and get the customer to approve the version you actually publish. Do that, and a quote in a language your prospects cannot read becomes one they can trust.
