I created a blog with all post in english and spanish, but google indexed it as spanish page. I'm investigating the cause. Does google see the language that I use in google webmaster tools page when I sent my sitemap? Does google see the country of owner of the domain in whois? In the whois of the domain the country is spain. If you want to see the blog is www.myblogsale.com , I have there a post with more details about the matter.
