Key Findings

We analyzed Ng.d.cn page load time and found that the first response time was 3.1 sec and then it took 26 sec to load all DOM resources and completely render a web page.

Unfortunately, there were 32 request timeouts, which can generally increase the web page load time, as the browser stays idle while waiting for website response.

  • Encoding

    UTF-8

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Ng.d.cn 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 Ng.d.cn 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.
