Lock the source message first
Do not translate a moving target. Confirm the source headline, offer, price, date and call to action before creating language versions. This prevents small source edits from producing mismatched posters and voiceovers later.
Keep a short list of protected terms: brand names, product names, URLs, coupon codes and legal wording that must not change.
Translate for meaning and available space
Languages expand at different rates. A phrase that fits on one line in English may need two lines in German or Spanish. Preserve the meaning first, then adjust the layout rather than forcing the translated copy into an unsuitable design.
Avoid idioms unless a native reviewer confirms the equivalent. Direct language is easier to validate and usually performs better in short-form advertising.
Review the high-risk details
These details cause more campaign problems than stylistic differences. Give them a dedicated review before generating media.
- Prices, currencies and decimal separators
- Dates, time zones and opening hours
- Units of measurement
- Phone numbers and destination URLs
- Claims, disclaimers and eligibility rules
Match the voice to the market
Choose the voice language deliberately instead of assuming the poster language is enough. Listen to names, abbreviations and numbers in the preview. Adjust speed when a translated script becomes longer, but avoid making the delivery sound rushed.
A native reviewer is still valuable for major launches. Use them where judgment matters most: the headline, offer, cultural fit and spoken pronunciation.
Build a reusable localization checklist
Save the approved source copy, protected terms and review notes with the campaign. For the next market, duplicate the process rather than rebuilding it. A repeatable checklist makes localization faster without treating every language as interchangeable.
