Normal result

IP address uses IP address which is currently shared with 1 other domain. The more sites share the same IP address, the higher the host server’s workload is. It is strongly recommended that the host server should be changed or the hosting provider should be requested to give a different (separate) IP address for this domain.

Language and encoding

JA ja language flag





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