Case Study: Merck KGaA scales website localization to 13 languages with DeepL

Merck KGaA localizes 1,930 pages in under a day with DeepL

Merck KGaA, a Germany-based science and technology company, needed to scale its highly technical SYNTHIA® Retrosynthesis Software website into multiple languages quickly without sacrificing translation quality. Their challenge was to localize the platform for a global audience of scientists while protecting their 350-year scientific reputation, as manual processes and generic AI tools were too slow and inaccurate. They turned to the DeepL API for a solution.

By integrating the DeepL API directly into their TYPO3 CMS, Merck enabled editors to translate content at the click of a button. DeepL's high-quality output, supplemented with custom glossaries for technical terms, allowed the team to adopt an "AI-first, human-in-the-loop" approach. The results were transformative: the localization process was reduced from months to less than a day, over 1 million characters were translated into 13 languages, and 70% of their top SEO results are now localized pages, with traffic from Brazil increasing by 600%.
