Why a checklist matters
Localization errors are expensive because they are public and slow to fix. A simple checklist prevents the most common issues: wrong units, broken hierarchy, and risky claims.
Use this checklist before every market launch to reduce rework and compliance risk.
Text and hierarchy
Translate headers and core benefits first. Keep visual hierarchy intact so the headline still reads as the headline.
If the language is longer, adjust leading before shrinking type. Legibility matters more than tight layouts.
Units and formats
Convert inches to cm, Fahrenheit to Celsius, oz to ml. This is not optional. Use the correct decimal separators for each market.
If you show dates, follow local format expectations to avoid confusion.
Claims and compliance
Avoid absolute promises if they are restricted in the target market. Replace broad claims with specific outcomes you can support.
Review sensitive words like "clinical" or "medical" and adjust tone accordingly.
Final check
Validate the first three slots with a native reviewer and a compliance checklist. Check every number and unit.
Confirm that no text overlaps important product areas.
Typography and legibility
Ensure the headline is readable on mobile. If the translation is longer, shorten the claim instead of shrinking the font.
Use consistent line spacing so the visual hierarchy stays clear.
Glossary and term control
Maintain a glossary of approved terms and banned words by market. This prevents inconsistent translations and reduces compliance risk.
Update the glossary based on performance and reviewer feedback.
Signals to review
Watch compliance flags and listing edits after upload. If issues appear, tighten claims and refresh the checklist.
Track buyer questions that indicate confusion and update the relevant slot.
Quick checklist
Confirm hierarchy, convert units, validate claims, and run native review on the top three slots.
Monitor compliance and buyer questions after launch.
