How to Use Google Translate API for Website Localization
Discover how the Google Translate API and Google Website Translator API enable seamless website localization. Learn the differences and how each supports multilingual content for your business.
What Is Google Translate API for Websites?
The Google Translate API for website localization lets you automatically translate your site’s content into 100+ languages. Unlike the Google Website Translator API, which offers a simple widget, the Google Translate API provides deeper integration and control for developers and businesses. Both options help you reach a global audience, but the API unlocks advanced workflow automation and customization.
Benefits of Integrating Google Translate API
• Instantly deliver multilingual content to global audiences
• Automate translation workflows for efficiency
• Scale website localization as your business grows

Yes. Smartcat supports website localization workflows that connect with existing content systems, helping teams manage translation, review, and publishing without rebuilding their whole operating model.
