This rule is triggered when PageSpeed Insights detects that you are using a synchronous version of the script instead of an asynchronous version.
Using asynchronous scripts means that the system can render your web page more quickly, rather than forcing users to wait for the script to complete downloading before rendering the web page. Asynchronous version of the script can be downloaded in the background.
Although most of the original scripts are synchronous, newer versions of scripts can be loaded asynchronously.
