Language and Encoding

  • Language Detected

  • Language Claimed

    N/A

  • Encoding

    GBK

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Taobao.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 Taobao.com main page’s claimed encoding is gbk. 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.

Social Sharing Optimization

taobao.com

Open Graph data is detected on the main page of Taobao. This is the best way to make the web page social media friendly. Here is how it looks like on Facebook:
