If you expand the suggestion, this is what you’ll read:
?nowprocket query to your URL (i.e:
https://www.example.com/?nowprocket) then you can identify the theme/plugin responsible for the script's URL:
frontend.min.js from Elementor builder plugin could save more than half of its weight in this case.
What can I do then?
In the example above, maybe the execution of the external /main.js loaded by widget.trustpilot.com could be delayed and not appear anymore in this diagnostic.
However, not every file can be safely delayed. You should only delay files which are not needed for anything “above the fold”. Please see our documentation for more details.
