Language and Encoding

  • Language Detected

  • Language Claimed

    KO

  • Encoding

    EUC-KR

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Yn.ms.kr 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 Korean. Our system also found out that Yn.ms.kr main page’s claimed encoding is euc-kr. 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

yn.ms.kr

Open Graph description is not detected on the main page of Yn Ms. 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:
