Page load speed is incredibly important to the overall health of a website. It plays a big role in search engine optimization, as slow page loading is one of the biggest reasons visitors decide to stay on or abandon a page. Page load speeds that are more than three seconds long can lose up to 40 percent of site visitors.

A page load test is a tool webmasters can use to measure page load speed performance, see where they can make improvements, make changes, and test again until they get the desired scores or results. Free page load tests such as Google Page Speed Insights exist to help webmasters optimize page speeds for better user experiences and search engine rankings.
