The best tools for measuring website speed and optimization
Google PageSpeed still provides very valuable data when it comes to optimization. However, as I’ve learned, it might not suit your visitors best to make sacrifices in order to achieve the best score. Render-blocking scripts and CSS minification might be better left alone. For me, FOUT (flash of unstyled text) and FOUC (flash of unstyled content) should absolutely be avoided. I’d rather have a few marks deducted on a score than compromise user experience. Google font swapping and content moving around during page load is both unsightly and distracting. In most cases, you may shave a little bit of time off but is it really worth it?
