Possible request optimization











Normal result

IP address uses IP address which is currently shared with 2 other domains. 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

Poor result


JA ja language flag


N/A  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. 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 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.
