Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Zefix.ch can be misinterpreted by Google and other search engines. Unfortunately we cannot identify language used on the page (probably there is a mix of languages, too little text or something else) and no language is claimed in <html> or <meta> tags either.
