Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Yamaha.com.cn can be misinterpreted by Google and other search engines. Our service has detected that Chinese is used on the page, and neither this language nor any other was claimed in <html> or <meta> tags. Our system also found out that Yamaha.com.cn main page’s claimed encoding is utf-8.
