Google PageSpeeds Insights Tool Gets A Major Update With More Data From Lighthouse

A new update to Google’s PageSpeed Insights tool has been quietly rolled out, which is the first large update since January 2018 when Google began using real user data from the Chrome browser to measure page speed of a site.  With this update brings Lighthouse, a speed tool from Google, as its analysis engine, and also incorporates field data provided by the Chrome User Experience Report (CrUX) into the tool.

Version 5 of the release notes says “v5 of the PageSpeed Insights API was released in November 2018. It now uses Lighthouse as its analysis engine and also incorporates field data provided by the Chrome User Experience Report (CrUX). v5 of the API will now provide CrUX data and all of the Lighthouse audits. Previous versions of the PSI API will be deprecated in six months.”

This is what the new report looks like.  Notice the two tabs, one for mobile and one for desktop:

Here is how the PageSpeed Insights dashboard looked like earlier this year:

The new toolset breaks up the report into several categories including:

  • Field Data: This uses the Chrome User Experience report and shows you the First Contentful Paint (FCP) and the First Input Delay (FID).
  • Lab Data: Lighthouse analysis of the current page on an emulated mobile and plots metrics from that tool including First Contentful Paint, Speed Index, Time to Interactive, First Meaningful Paint, First CPU Idle, Estimated Input Latency and then shows screen shots of how this is viewed.
  • Opportunities: Shows you ways to improve the performance of that specific page including the areas of issues and how much they are slowing down your page.
  • Diagnostics: This gives you a report on the performance of your application for things like caching, DOM size, payloads, JavaScript and much more.
  • Audit: Then the report shows you how well you did on various audits including Minify JavaScript, CSS, redirects and so much more

Site speed isn’t the only important factor to consider when ensuring your web site is ranking well in Google search Speed Update.  It can improve the user’s experience as well as the conversion rates on your web site.  This update to the PageSpeed Insights tool has vastly improved the data and metrics around how to measure your page speed.  There are many ares where it gives you the ability to make improvements to your pages and thus, increase your pages speed.
