Language and Encoding

  • Language Detected

    JA

  • Language Claimed

    N/A

  • Encoding

    SHIFT_JIS

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Edogawa.karou.jp can be misinterpreted by Google and other search engines. Our service has detected that Japanese 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 Edogawa.karou.jp main page’s claimed encoding is shift_jis. 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

edogawa.karou.jp

Open Graph description is not detected on the main page of Edogawa Karou. 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:
