Does anybody know how Google treats bilingual pages? That is most pages of the site have almost equal amount of text in 2 different languages. For example, English lessons for Russian speakers, English-Chinese phrase book, etc. Will such site gain traffic from Google with requests on both languages or gain nothing? Does anybody have similar experience with bilingual pages (2 languages on the same page, equally)? Other search engines are also interesting but I won't copy the same question in other areas.
