Google made some big changes to their PageSpeed Insights tool last week. The tool is now officially powered by Lighthouse, making the diagnosis of web performance a lot more comprehensive.

The tool also now uses real-world performance metrics powered by the Chrome User Experience Report (CrUX) segmented from the 'lab' data in Lighthouse. This is such a powerful extension of the tool, as you can now get a real sense of the performance of your website, in your customer's shoes.

It allows you to dig a little deeper. For example, for one of my clients with an extremely slowly First Contentful Paint (FCP) on mobile in the CrUX report, I've been able to dive into the most popular devices and browsers where page speed is a real problem, and then use Web Page Test to provide isolated recommendations for devices and browsers.

Go do your own forensic SEO on real-world data. It also makes consulting and advocating recommendations a whole lot easier.
