Google PageSpeed Insights now use real-world data from Google Chrome

January 29, 2018 0 comments

According to a recent announcement by Google, Google PageSpeed Insights has been updated to give even more insights by using real-world data from Google Chrome browsers.

Google recently announced that they had updated Google PageSpeed Insights. Now the Google PageSpeed Insights tool use real-world data from the Google Chrome user experience report. In other words, Google Insights uses metrics from “real-world Google Chrome users who experience popular destinations on the web” and shows you fast your web pages load based on real user data.

 

The speed of the web pages is graded as per three categories: fast, slow, and average.

 

  • ‘Fast’ represents that the median value of the metric is in the fastest third of all page loads.
  • ‘Slow’ represents that the median value of the metric is in the slowest third of all page loads.
  • ‘Average’ represents that the median value of the metric is in the middle third of all page loads.

 

According to Google’s announcement, the Google PageSpeed Insights tool has the following features:

 

  • The Speed score categorises a page as being Fast, Average, or Slow. This is determined by looking at the median value of two metrics: First Contentful Paint (FCP) and DOM Content Loaded (DCL). If both metrics are in the top one-third of their category, the page is considered fast.
  • The Optimisation score categorises a page as being Good, Medium, or Low by estimating its performance headroom. The calculation assumes that a developer wants to keep the same appearance and functionality of the page.
  • The Page Load Distributions section presents how this page’s FCP and DCL events are distributed in the data set. These events are categorised as Fast (top third), Average (middle third), and Slow (bottom third) by comparing to all events in the Chrome User Experience Report.
  • The Page Stats section describes the round trips required to load the page’s render-blocking resources, the total bytes used by the page, and how it compares to the median number of round trips and bytes used in the dataset. It can indicate if the page might be faster if the developer modifies the appearance and functionality of the page.
  • Optimisation Suggestions is a list of best practices that could be applied to this page. If the page is fast, these suggestions are hidden by default, as the page is already in the top third of all pages in the data set.

Happy optimising!
