On my website, I check “Remove emojis” and “Remove query strings from static resources”. Since I don’t use emojis on my site, removing the associated JS and CSS bloat reduced my page load time.

As demonstrated in this post, optimizing a WordPress site doesn’t have to be an expensive endeavor. For most WordPress users, there’s simply no need to invest in an expensive optimization plugin like WP-Rocket. Autoptimize, a free plugin, does a great job of optimizing your HTML, CSS, and JS. When combined with a top tier web host like
