User Bounce Rate and Page Load Time

Simon Biar - Wednesday, February 07, 2018

According to Google's mobile page speed study, as the web site page load time increases on a mobile device, from one second to six seconds, the web site user bounce rate increases by 106%. (Bounce rate: The percentage of single-page sessions in which there was no interaction with the page. A bounced session has a duration of 0 seconds).

Effect of increased page load time on user bounce rate

Page load speed has been used as a ranking signal for quite some time, though it was mostly focused on desktop or laptop searches. As mobile search becomes a greater volume of overall searches, Google announced their Mobile Speed Update which will start to be implemented from July 2018. This update basically means that page load speed will become a more important ranking factor for mobile searches.

Google does suggest that this update will affect only a small percentage of web site pages that deliver the slowest experience to its users. Google does indicate that the actual search query stays a very strong ranking signal meaning that the slowest pages can still rank well providing they have great, relevant content.

Mobile Users

A recent eMarketer artice suggest that 80% of mobile users will leave a site that is slow to load or switch to another device (https://www.emarketer.com/content/half-of-u-s-users-stop-viewing-content-slow-to-load).

This reinforces the justification for the Google change.

  2. This is one are where Wordpress sites, because of the Wordpress plugin architecture, oftentimes suffer quite badly. Unfortunately, this is one case of 'you get what you paid for' ... and Wordpress is Open Source, or free. This is why we do not recommend using WordPress or other 'free' platforms.
