  • Encoding

    GB2312

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Jzcodes.com 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 Jzcodes.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.

Lack of Open Graph description can be counter-productive for their social media presence, as such a description allows converting a website homepage (or other pages) into good-looking, rich and well-structured posts, when it is being shared on Facebook and other social media. For example, adding the following code snippet into HTML <head> tag will help to represent this web page correctly in social networks:
