Optimize Core Web Vitals for WordPress [with WP Rocket 3.9]

So you want to improve your Core Web Vitals for your WordPress website?
WP Rocket 3.9 revolves around two main enhancements which are Delaying JS execution and Removing Unused CSS.

The first new one should improve the FID by addressing the “Reduce JavaScript execution time” recommendation and boost your LCP score by addressing the “Remove unused JS” and “Eliminate render-blocking resources” PageSpeed Insights recommendations.

The second one addresses Google’s recommendation to “Remove unused CSS” and should have a positive effect on the LCP and the FID metrics as a result.

Both enhancements should result in an improvement of your Core Web Vitals metrics and PageSpeed Insights score, on top of a better loading time and perceived speed of your website.
