Hello all. I've run my website through Semrush, and it says pretty much all pages on my website have unminified Javascript and CSS files, which is affecting loading time. Can anyone tell me how I can minify them, or increase my website speed? Another website told me my speed is within acceptable siza parameters, but I wonder if the 3-4 second load time for certain pages is unacceptable if I want to keep customers on my website.
