Every international marketing failure I have studied gets blamed on translation. Almost none of them are.
A campaign lands well at home, gets rolled out abroad with the words swapped for the local language, and quietly underperforms. The postmortem usually reaches for translation. Something got lost in the wording, the idiom did not carry, the tone came out wrong. Fix the copy, try again next quarter.
Translation is rarely the actual problem, because translation was never the hard part. The hard part is that the campaign was built on proof the new market does not have.
Claims travel. Proof does not.
A line like “trusted by thousands” or “the UK’s favourite” is a claim wearing the costume of proof. In the home market, that costume works because the audience already half believes it from context: they have seen the brand on the street, heard a friend mention it, noticed the logo somewhere ordinary. The claim is really just confirming something the audience was already inclined to accept.
Move that same line into a market with zero ambient exposure, and the claim has nothing to confirm. It just sits there asking to be taken on faith from a brand nobody has context for. Translating it accurately makes it grammatically correct and no more convincing. The sentence was never doing the persuading. The context around the sentence was, and that context did not ship with the copy.
Re-arguing, not re-wording
The actual work of going into a new market is re-arguing the case from scratch, using evidence that market will actually credit. Sometimes that means finding a local proof point instead of importing a global one: a domestic partnership, a local reviewer, a comparison to a competitor the audience already knows and trusts less. Sometimes it means leading with a different benefit entirely, because the thing that made the brand famous at home is not the thing this audience is short on.
This is a slower, less flattering process than translation. Translation lets a team believe the hard creative work is done and only the language remains. Re-arguing admits the hard creative work was specific to a market that no longer applies, and most of it has to happen again, with different raw material, for every market that matters.
The tell that you are only translating
A useful test: read the local-market version of a campaign and ask what evidence it is actually offering, not what claim it is making. If the evidence is “trust us, we work everywhere,” that evidence is imported and it is thin. If the evidence is specific to that market, a name, a number, a comparison the local audience recognises, someone did the re-arguing. Most campaigns fail this test quietly, because a fluent translation reads as finished even when the underlying argument was never rebuilt.
The brands that expand well tend to treat each new market less like a language to convert into and more like a jury that has not seen the earlier evidence. You do not read the same closing argument slower and louder in a different accent. You bring the exhibits that jury will actually find credible, even when that means the argument itself changes shape from market to market while the underlying claim stays the same.
Where this shows up smaller than “international”
You do not need a passport for this lesson to apply. The same gap shows up moving a B2C campaign into a B2B context, or moving a message built for early adopters in front of a cautious, risk-averse buyer. The claim survives the move intact. The proof it was leaning on does not, because the new audience has different defaults for what counts as credible. “International” is just the version of this problem that is hardest to ignore, because the language mismatch makes the underlying proof mismatch impossible to paper over with familiarity.
If you are thinking through a market expansion and want a second opinion on which parts of the argument actually need rebuilding, I would be glad to hear about it. Get in touch, or see the Work page for more of the thinking behind this.
