PageSpeed Insights Tool by Google Now Uses Real-world Data from Chrome

Google’s PageSpeed Insights tool that provides information about how a webpage adheres to a set of best practices gets revamped to now give users more insights like how fast the webpage load in the real world.

Towards this end, Google has updated the PageSpeed Insights to use the data from the Chrome User Experience Report (CrUX) to dispplay real-world peformance about a page.

In addition the optimization score has also been now more aligned with the real-world data.

The PSI reports two metrics, first Contentful Paint (FCP) and second DOMContentLoaded (DCL). “The median value for each metric (FCP or DCL) is compared to all the pages monitored by the CrUX report,” explains Google. Pages are graded depending on where it falls in the distribution based on these level:

Fast: The median value of the metric is in the fastest third of all page loads.
Slow: The median value of the metric is in the slowest third of all page loads.
Average: The median value of the metric is in the middle third of all page loads.
An overall Speed score is calculated by looking at the categories for each metric:

Fast: If every metric of a page is Fast.
Slow: If any metric of a page is Slow.
Average: All other cases.

The PSI tool now provides the following features, such as:

  • The Speed score categorizes 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 Optimization score categorizes 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 categorized 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.
  • Optimization 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, describes Google.
