Google have released a major update to their PageSpeed Insights tool which uses more data from Lighthouse. Version 5 is now out for the Google PageSpeed Insights, and this has brought much more information to the system and different reporting/scores.
Google have actually been slowly rolling out its new updates to the PageSpeed Insights tool, the initial update was back in January when Google started to use real user data from its Chrome browser to check on the page speed of a website.
The newest update now uses ‘Lighthouse’ which is a speed tool created by Google, Lighthouse is the analysis engine and to make it even more accurate it incorporates field data, this is provided by the Google Chrome User Experience Report (CrUX).
In the release notes it states that:
“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.”
What information is in the Lighthouse tool?
The new Google Lighthouse toolset provides you a report which includes a few different categories, this includes:
Field Data: This uses the data issued in the Chrome User Experience report and from that will display the ‘First Contentful Paint’ (FCP) and also the ‘First Input Delay’ (FID).
Lab Data: Google Lighthouse will analyse a number of things such as First Contentful Paint, Speed Index, Time to Interactive, First Meaningful Paint, First CPU Idle, Estimated Input Latency after this has been analysed it will display screenshots of how this is working.
Opportunities: This section will display ways in which you can look at improving the performance of your web page such as what are causing issues on your page and how they are affecting the speed of your page.
Why does it matter?
So you might be wondering why does all this matter and why do I need to see this information? The reason is that making your website run and load faster is important, not just because it helps improve your rankings with Google and Bing but it will also reduce your bounce rate and improve user experience and conversion rates too!
This Google Insights update has massively improved the amount (and quality) of data and metrics therefore giving you the best chance to review your website and then make improvements to increase the speed of your website.
