How do I redirect users by language?
Open Tools > Redirect by Language. For each language you want to handle, pick the language from the dropdown and enter the destination URL. Add a fallback URL for languages you haven't explicitly listed. Click Create Link.
When someone clicks your short link, we look at their browser's language preference and redirect them to the matching destination. One link, and each visitor lands on the version of your site that matches their language.
Languages are identified by their standard two-letter code (e.g. en for English, fr for French, de for German).
