PageSpeed Insights tool
Google has rolled out a new update to
its PageSpeed Insights tool, the first large update
since early 2018 and that was when Google began using real user
data from the Chrome browser to measure page speed of a site. The new
update today uses 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.
