Page optimization

  • HTML 122 B
    Images 151.4 kB
    Javascripts 147.3 kB
    CSS 1.2 kB

    In fact, the total size of main page is 300.0 kB. This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 65% of websites need less resources to load. Images take 151.4 kB which makes up the majority of the site volume.

    • Original 122 B
    • After minification 113 B
    • After compression 90 B

    • Original 1.2 kB
    • After minification 820 B
    • After compression 328 B

As for redirects, our browser was forwarded to before it reached this domain.

IP address uses IP addresses which are currently shared with 8 other domains. The more sites share the same stack of IP addresses, 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

Normal result

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. 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 main page’s claimed encoding is . 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.
