Search Engine Optimization Advices

Language and Encoding

  • Language Detected

    N/A

  • Language Claimed

    N/A

  • Encoding

    SHIFT_JIS

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Casterhouse.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) and no language is claimed in <html> or <meta> tags either. Our system also found out that Casterhouse.co.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

casterhouse.co.jp

Open Graph description is not detected on the main page of Caster House. 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:
