Possible request optimization













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

Poor result


ZH zh 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 Chinese 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 gb2312. 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 22.1% of all visits is United States. It lies approximately 7060 miles away from the server location (China) 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 United States or just closer to the user base.
