The Translation Was Word-Perfect. The Joke Died in Madrid.
A project management tool ran the line "Get your whole team on the same page" across its UK ads for two years. It pulled its weight.
Then they opened in Mexico. The headline went to a translation service and came back as "Pon a todo tu equipo en la misma página". Accurate, grammatical, signed off, shipped.
It reads as putting your colleagues onto a physical sheet of paper. The idiom doesn't exist there. The landing page converted at roughly a third of the UK rate for six weeks while the team dug through audience targeting, bid caps and page speed looking for the problem.
Four minutes of the right prompt would have caught it before launch.
The prompt
Adapt a Campaign Headline for a New Market Without Breaking It treats the job as transcreation rather than translation. You hand it the source copy, both markets, what the product does, your brand voice in three adjectives, the terms that must never change, and your character limits.
It hands back three options. Each one carries a back-translation into your own language, so you can audit the meaning without speaking a word of the target language. That back-translation is the whole trick. It turns a black box into something a monolingual marketer can actually check.
What comes back
Feed it the same headline, target Mexican Spanish, brand voice "practical, warm, never corporate", character limit 45, and you get something close to this:
| Option | Adapted copy | Back-translation | Chars |
|---|---|---|---|
| 1 | Todo el equipo, el mismo plan | The whole team, the same plan | 29 |
| 2 | Que nadie trabaje a ciegas | So no one works blind | 26 |
| 3 | Tu equipo, coordinado desde el primer día | Your team, coordinated from day one | 41 |
Underneath the options it flags what the literal version would have cost you:
- Idiom that doesn't travel. "On the same page" is English-specific. The direct Spanish reads as a physical page, so the options swap in "plan" and "coordinado" to carry the intent.
- Register risk. Option 2 uses an informal address that fits Mexico and would land badly in a formal B2B pitch in Colombia. Worth a local speaker's eye before it runs.
- Recommendation. Option 1, because it keeps the rhythm of the original, fits a mobile ad slot at 29 characters, and holds the offer intact.
Where the money is
Six weeks of paid traffic at a third of the normal conversion rate is a real number, and the diagnosis cost more than the fix. Teams chase the media buy when copy is the thing that broke, because the copy came back from a professional service and looked correct.
The back-translation column closes that gap. You read it, you spot that the meaning drifted, you ask one question before launch instead of six weeks after it.
Second use: the risk flags give you a short, specific brief for a native reviewer. Paying someone to check three flagged lines costs a fraction of paying them to review the whole campaign cold.
How to run it
- Gather the inputs before you start. Source headline, subhead and call to action, both markets, your do-not-translate list (product names, taglines, anything with legal wording), and the exact character limits from your ad platform. The prompt gets noticeably sharper when the limits are real rather than guessed.
- Run it for one market at a time. "Latin American Spanish" papers over the distance between Mexico City and Buenos Aires. Run it separately for every market you're buying media in.
- Send the flags to a local speaker. Take the recommended option and the risk list, and ask one person in-market to confirm. That's a ten-minute favour to ask.
