Ck12.org Website Load Time
Website load time is an important factor, because Google is taking the site’s loading speed into consideration in determining its ranking. Even though this will not have a big impact, it is still something we (webmasters) should really look into. The reason is pretty simple – the majority of visitors are usually in a rush and no one is fond of waiting half a century before the website finally loads its content or fails to load. At the last check on 2016-08-30, website load time was 0.02. The highest load time is 0.71, the lowest load time is 0.02, the average load time is 0.14.
