Language and Encoding

  • Language Detected

    N/A

  • Language Claimed

    JA

  • Encoding

    UTF-8

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Rakus.co.jp 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 Japanese. Our system also found out that Rakus.co.jp main page’s claimed encoding is utf-8. Use of this encoding format is the best practice as the main page visitors from all over the world won’t have any issues with symbol transcription.

For example, adding the following code snippet into HTML <head> tag will help to represent this web page correctly in social networks:
