Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Baoduhoc.vn 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), while the claimed language is Vietnamese. Our system also found out that Baoduhoc.vn main page’s claimed encoding is utf-8. Use of this encoding format is the best practice as the main page visitors from all over the world won’t have any issues with symbol transcription.
