Google: We Look At Language On A Per Page Basis, Not Site Wide Basis

This is just a reminder, that Google says it does not look at the language of your site overall but rather the language of each of your individual pages on your site. So you can have some pages in English, some in Spanish, some in Hebrew, etc. Just don't mix the languages on the same page, the same URL.
