    • Original 417.0 kB
    • After minification 376.4 kB
    • After compression 129.0 kB

    JavaScript optimization

The diagram shows the current total size of all JavaScript files against the prospective JavaScript size after its minification and compression. It is highly recommended that all JavaScript files should be compressed and minified as it can save up to 288.0 kB or 69% of the original size.

    • Original 26.0 kB
    • After minification 17.7 kB
    • After compression 4.8 kB

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.
