What is page speed?

Page speed is the measure of a web page’s loading time. High page speed ensures a great user experience.Footnote 1 Google considers load times when ranking relevant search results, so fast page speed is also key for search engine optimization (SEO) and generating organic traffic.Footnote 2 There are several metrics to measure page speed, such as:Footnote 3

  • Time for the initial server response (time to the first byte)

  • Time to load all resources (such as images, scripts, and stylesheets)

  • Time it takes for the page to become fully interactive

Slow page speed can lead to dissatisfaction among site visitors, resulting in higher bounce rates and lower conversion rates, ultimately impacting the overall success of online businesses.Footnote 4
