Why do webpage testing tools tell me to do things I've already done?

The google pagespeed insights tool and webpagetest.org both tell me that I need to optimize images, leverage browser caching, and minify javascript and CSS. Yet I have already optimized ALL of my images with a plugin, tried multiple caching plugins, and minified my Javascript and CSS with a plugin. So why do the tests still say I need to do these things?

    If you're using source maps, that may be the reason.

    I don't know what a source map is, so I don't know if I'm using them. I am using a plugin called Ewww Image Optimizer to optimize the images, WP Fastest Cache for caching, and Autoptimize to minify the html, javascript, and css. Does anybody know if those plugins use source maps?

    Btw, Autopimize says it optimizes the html, javascript, and css. Not sure if minifying them is part of that optimization process, but I think it is.

    Pay close attention to wording, sometimes Google Insights (for example) asks you to resize your images.
    For example you could use a 1024x768 and shrink it to fit a 200x150 slot.
    This kind of image should be resized as well besides being optimized.
