Language and encoding

Poor result


RU ru language flag


EN en 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 Russian is used on the page, and it does not match the claimed English language. Our system also found out that main page’s claimed encoding is windows-1251. 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.

HTTPS certificate

SSL Certificate has no SSL certificate. Web browsing can be safer with HTTPS connection, so we suggest that it should be obtained for this site.

Normal result

Visitor World Map

Country of origin for 25.9% of all visits is Russia. It lies approximately 3370 miles away from the server location (Netherlands) and such a long distance can negatively affect website speed, as it takes some time for data to travel back and forth between those places. That’s why one of the best ways to speed up page load time for the majority of users is moving the server to Russia or just closer to the user base.
