Key Findings

We analyzed 0d.su page load time and found that the first response time was 503 ms and then it took 22.8 sec to load all DOM resources and completely render a web page. This is a poor result, as 95% of websites can load faster. Unfortunately, there was 1 request timeout, 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 0d.su can be misinterpreted by Google and other search engines. Our service has detected that Russian is used on the page, and it matches the claimed language. Our system also found out that 0d.su 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.
