The top lists point out the specific files to fix first: the largest and slowest assets across all tested pages, and the assets returning visitors have to download again.
Every JavaScript byte is downloaded, parsed and executed on the main thread, so trimming the biggest bundles pays off twice.

CSS blocks rendering until it is downloaded and parsed, so the biggest files delay first paint the most.

Images are usually the easiest bytes to win back: resize them, compress harder or switch to a modern format like AVIF or WebP.

Web fonts often keep text invisible until they arrive. Subset the biggest ones or use font-display to show text earlier.
