Hi @clivedav,
First, please confirm that Jetpack Boost’s minification and defer non-essential JavaScript option is also enabled, as these will further optimize your files.
Second, while enabling the “Concatenate JS” and “Concatenate CSS” features in Jetpack Boost is a good start, it’s crucial to specify the JS and CSS strings that need to be concatenated. This is because Boost needs to know which files to combine into a single file to reduce the number of HTTP requests and improve load times. When enabled, an option to exclude specific JavaScript strings becomes accessible. Click on this option, enter the JavaScript scripts you wish to exclude in the provided field, and then click Save. Simiar for CSS.
To do this, you should provide a list of the JS and CSS strings that you want to concatenate in the respective settings within Jetpack Boost. By specifying these strings, you ensure that Boost combines them as intended, optimizing your website’s performance and addressing the SEMRush warnings about uncompressed JS and CSS files.
Let us know if this helps.
Hi Alin,
Thank you for your message. Unfortunately I’m not technical enough to know which scripts to exclude so have just turned these options off and regenerated the Critical CSS. This helped and moved my JetPack Boost Overall scores up by 10% for mobile and desktop.
Thanks,
Clive

I just had and issue in which the links and my variable attribute products stopped working on my Divi Theme site. By disabling the JS Concatenate feature of JetPack Boost, seemed to fix these issues.
Hi @kartmanco,
The issue you experienced likely arose from script conflicts when the JS Concatenate feature in Jetpack Boost combined your scripts, affecting the functionality of your Divi Theme site. Disabling this feature can prevent such conflicts by keeping scripts separate.
