Language and Encoding

    N/A

  • Encoding

    GB2312

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Yzdrzw.com 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. Our system also found out that Yzdrzw.com main page’s claimed encoding is gb2312. Changing it to UTF-8 can be a good choice, as this format is commonly used for encoding all over the web and thus their visitors won’t have any troubles with symbol transcription or reading.
