Multilingual Website: Definition and Key Concepts
What is a multilingual website?
A multilingual website is a site that offers its content in multiple languages to reach users who speak different languages.
Unlike a multiregional site (which targets multiple countries), a multilingual site primarily focuses on the user’s language, regardless of their geographic location.
Example:
A website available in French, English, and Spanish to reach an international audience.
