Dev Tools includes:

Search for sessions where the Page Load time took longer than expected or open Dev Tools for any customer's session to see exactly what the Network requests looked like in their browser for any page that loaded during their session.

Dev Tools can help you answer business questions like…

  • Which pages load the most slowly for my customers?

  • Do people convert at a better rate when my page loads faster?

  • Was the page slow for everyone or just this one person?

  • Which image, file, or script was causing my site to load slowly for my customer?

  • How many of my customers encountered slowness on this page?

Page Speed Metrics

Page speed metrics allow you to see page timing milestones for every page that loads during any session. 

Available metrics include:

  • DOMContentLoaded

  • First Contentful Paint, and

  • Load Time

Together, these page speed metrics can help you understand whether a page was rendering or loading slowly for any individual user. And, because page speed metrics are available as search criteria for OmniSearch and Segments, you can layer these timings onto any of your funnels or Segments to learn more about performance in the context of specific pages or groups of sessions.

Slowest Pages

The Slowest Pages report shows you the slowest pages related to any search or segment, by First Contentful Paint. You can find Slowest Pages for any search or segment, and this report gives you excellent signal to understand where to improve your performance and also where you might want to search to find slow sessions.
