What language will be displayed?
The first matching will be picked:
- If the user was (within the last year) on the site, a cookie has been set and the preferred language of that user is shown
- The preferred languages supplied by the browser will be used
- The default language you specified
In which language are the Feeds
In the system default language.
What about bots?
Bots (everything with a "bot" in the user agent) will see a different page:
- Cookies and preferred browser languages will not take place
- On a post page all texts are visible
- On other pages (like home, archive, ...) only the system default language will be used
Maybe this is not perfect, please mail me if you know a better way.
