Redirects

As for redirects, our browser reached this domain in four steps. The first redirect led to http://shop36551478.taobao.com, then it was forwarded to https://shop36551478.taobao.com/, and afterwards it was sent to http://shop36551478.world.taobao.com/ and a few other URLs (see the full list below) before we finally managed to reach this website. We strongly recommend that the redirects should be reduced, as the more redirects a site has, the slower it loads.

IP address

Nio.cn uses IP addresses which are currently shared with 6 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.

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 Nio.cn main page’s claimed encoding is gbk. 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.

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

Visitor World Map

Country of origin for 96.3% of all visits is China. It lies approximately 6910 miles away from the server location (United States) 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 Nio.cn page load time for the majority of users is moving the server to China or just closer to the user base.

For example, adding the following code snippet into HTML <head> tag will help to represent this web page correctly in social networks:
