Website translation often requires integration with CMS platforms, multilingual SEO strategies, and ongoing updates. Tools like Weglot and Smartling excel here.
Document translation, on the other hand, focuses more on formatting consistency, certification, and confidentiality. Services like TransPerfect and Day Translations are strong choices for these tasks.

Pricing varies widely based on language pair, complexity, and urgency:
- AI translation: Often free or subscription-based.
- Human translation: Typically $0.08–$0.25 per word.
- Certified documents: May range from $20–$100 per page.
- Enterprise localization: Custom pricing models.
