There seems to be two ways to specify the language of a page:<meta http-equiv=Content-Language content=en-us>and<html lang=en-us>Which one is the preferred way? I know I could just add both tags but I'd rather not have duplicate content.Also do both methods use the same locale format (i.e. en-us and not en_US)?
Which method is the best to specify the language of a page?
html;meta tags
