WP Rocket is a premium WordPress caching and performance plugin. Where most caching tools expect you to understand page cache, object cache, minification and lazy loading before you touch anything, WP Rocket turns on sensible defaults the moment you activate it and lets you tune from there.
We have run it on client sites for years, from small local-service brochure sites to content-heavy publishers. It is the first plugin we reach for when a site fails Core Web Vitals, and it is part of the standard build on every site we host.
What it actually does
Page caching, browser caching, GZIP, CSS and JavaScript minification and delay, lazy loading for images and iframes, database cleanup, and a CDN integration. The Remove Unused CSS feature alone has moved several client sites from a failing to a passing LCP score.
