WP Rocket is a caching plugin for people who want a faster site without spending a weekend learning how caching works. Turn it on and it starts caching pages straight away, which means repeat visitors get a ready-made page instead of waiting for WordPress to build one from scratch. It also tidies up your CSS and JavaScript files, removes the render-blocking files that slow the first paint, and lazy loads images and videos so they only load when someone scrolls to them. Database clean-up is built in as well, clearing out old revisions, spam comments and expired transients that pile up over time. The settings page is short and plain, with each option explained in normal language, and there is a separate tab for preloading the cache so your pages are ready before anyone visits. It works with most hosts and most page builders, and it plays nicely with Cloudflare if you use it. If your site feels slow and you are not sure why, this is usually the first plugin to try.
