Here in Latin America it looks like the domain extensions are influencing G. G won't pick up content from a country-specific domain that is in the "wrong" language. Say, if you have a .co.cr domain (for Costa Rica, which is de facto a bilingual country) and the website has both an English and a Spanish side, G just won't index the English pages. Right now this particular site that we designed and optimized is showing up in #1, 3, 10, in several search strings in Spanish but not at all in English. It is hosted in Germany, by the way. On the other hand, we optimized a .com site, hosted in the US, with an index in 2 languages and it shows up if you look for it either in Spanish or English. It won't show up, though, if you choose the "Show only pages in Costa Rica" button in G. So what I do now is register both a .com and a .co.cr domain for bilingual sites. At least in this case it does not seem to matter where it's hosted.
