> **Quick answer —** User-generated content is translated on demand rather than in batches, because volume and language mix are unpredictable. Label it as machine translated, moderate before translating, and cache results.[Vitra.ai Universe](https://www.vitra.ai/platform) creates, translates, adapts and publishes from one place.

## You cannot pre-translate what you do not have

A catalogue has a known number of pages. A review section does not — it grows continuously, in whatever languages your customers speak, and most individual items will never be read. Batching that is waste. Translating on request, then caching, matches the cost to the demand.

## Moderate first, translate second

This ordering matters and is easy to get backwards.

Translating abusive or fraudulent content before checking it means you have produced a polished version of something that should not be published, in languages the original author does not even speak.

Run moderation on the original, then translate what survives — which is also cheaper, because you are not paying to translate content you will remove.

## Label it honestly

Practice

Why

Mark as machine translated

Sets expectations, and is increasingly expected

Show the original

Bilingual readers check

Offer "show original"

One click, always available

Do not translate the reviewer's name

It is a name

Keep the original rating

Never derived from translated text

Labelling is not a disclaimer for poor quality. It is what stops a reader attributing an awkward phrasing to the reviewer rather than to the translation, which matters because the reviewer's credibility is what makes the review useful.

## The quality bar is different

Nobody expects a translated review to read like marketing copy. They expect to understand it.

So the bar is comprehension, not polish, and the failure modes that matter are inverted sentiment, a negation dropped, or a rating contradicted by the translated text. Those are worth checking; awkward phrasing is not.

[Quality control](https://www.vitra.ai/features/quality-control) can flag sentiment mismatch between the original and the translation, which is the check with the highest value here and the one nobody runs.

## Consistency with your own content

Product names in a translated review should match your catalogue, or search inside the reviews breaks and the page reads as two systems stitched together.

That comes from the same [memory](https://www.vitra.ai/features/translation-memory) your own content uses, applied to the on-demand path — which is the argument for handling [real-time and batch](https://www.vitra.ai/general/batch-vs-realtime-translation) through one system rather than bolting a translation widget onto the page.

Where the inbound text is evidence rather than commentary, register has to survive — [public consultation translation](https://www.vitra.ai/government/public-consultation-translation).

## FAQ

**Should user-generated content be translated in advance?** No. Volume and language mix are unpredictable and most items are never read, so translating on request and caching the result matches cost to actual demand.

**Should moderation run before or after translation?** Before. Translating first means producing polished versions of content that should not be published, in languages the author does not speak, and paying to translate what you will remove.

**Does translated user content need labelling?** Yes. Marking it as machine translated and offering the original stops readers attributing awkward phrasing to the reviewer, which is what preserves the reviewer's credibility.

**What quality checks matter for translated reviews?** Sentiment mismatch, dropped negations and text contradicting the star rating. Awkward phrasing does not matter much, because the bar for user content is comprehension rather than polish.
