A Quality Checklist for Multilingual Content

CorrectNow Editorial Team · 6 min read

Publishing the same content in several languages multiplies the chances of small mistakes. A typo copied into every version, a date in the wrong format, a button label that no longer fits, a paragraph that never got translated: each one looks minor, but together they make content feel untrustworthy.

This checklist covers the main stages of multilingual content, from preparing the source text to the final review. Use it as a starting point and adapt it to your own workflow.

Before translation: get the source text right

Every error in the source text is copied into every language. Fixing the original first saves time and money later.

Write in plain language, avoid idioms and keep terms consistent. Ambiguous sentences produce inconsistent translations, because each translator or tool may read them differently.

Proofread the source for spelling, grammar and punctuation.
Remove idioms and culture-specific references where possible.
Create a glossary of key terms and product names, with notes on what not to translate.
Mark text that must stay the same, such as brand names and code.

During translation: meaning, tone and terms

A good translation says the same thing in a way that sounds natural to native readers. Word-for-word accuracy is not the goal; accurate meaning is.

Check that the tone suits the audience. Some languages distinguish formal and informal forms of "you", such as French tu and vous or German du and Sie. Decide which one your brand uses in each language and apply it consistently.

Is the meaning complete, with nothing added or left out?
Are glossary terms used consistently?
Is the formal or informal register correct and consistent?
Do examples, references and humour make sense in the target culture?

Language checks: spelling, grammar and punctuation

Translated text needs proofreading just like original text. Pay special attention to rules that vary between languages: accents and diacritics, capitalisation, quotation marks and the spacing around punctuation.

A multilingual proofreader is a fast way to catch the obvious errors in every version. CorrectNow checks spelling, grammar and punctuation in 150 languages, and its translator includes a Proofread this option for checking translated text. Automatic checks are a first pass; they do not replace a native reviewer.

Formatting, scripts and layout

Many multilingual errors are not language errors at all but display problems. Translated text is often longer or shorter than the original, so labels and headings may overflow or leave gaps.

Check every language in its final layout, not just in a spreadsheet or document.

All text uses Unicode, with fonts that support every script.
Right to left languages such as Arabic and Hebrew have the correct paragraph direction.
No text is cut off in buttons, menus or headings.
Images with text inside them have been localised or replaced.
Line breaks do not split words or names awkwardly.

Locale details: dates, numbers and currency

Dates, numbers and money are easy to overlook because they look the same in every language. They are not. Date order differs between countries, and some languages use a comma as the decimal separator where English uses a full stop.

Confirm that each version uses the conventions its readers expect, and that prices, phone numbers and addresses are correct for that market.

Names deserve a check too. Make sure people's names keep their correct spelling and accents in every version, and that names written in other scripts use the form the person or organisation prefers.

Final review and publishing

Before publishing, have a native speaker read each version in its final form. They will notice phrasing that is technically correct but sounds unnatural, which automated checks often miss. For legal, medical or official content, use a qualified professional.

For websites, a few technical checks also matter for search engines and users.

Each page declares its language correctly.
Language versions are linked to each other, for example with hreflang tags.
Links point to the same-language version of other pages.
Page titles and descriptions are translated, not left in the source language.
There is an easy way for users to switch languages.

Frequently asked questions

What is the most common mistake in multilingual content?

Errors in the source text that get copied into every language. Proofreading and simplifying the original before translation prevents many later problems.

Is machine translation good enough for multilingual content?

It can be a useful first draft, especially for internal or informal content. Published, legal, medical and official content should be reviewed by a native speaker or professional translator.

How do I check content in a language I do not speak?

Use automatic proofreading to catch obvious errors, check the layout yourself, and ask a native speaker to review the meaning and tone before publishing.

Who should do the final review of translated content?

Ideally a native speaker of the target language who also understands the subject. They can judge meaning, tone and natural phrasing, which are the areas where automatic tools are least reliable.
