WP Rocket is the most popular premium WordPress caching plugin, known for its ease of use and performance improvements right out of the box. It activates page caching, cache preloading, Gzip compression, and browser caching immediately upon installation. The plugin includes CSS and JavaScript minification, database optimization, lazy loading for images and iframes, and CDN integration. The Pro version adds critical CSS generation, delay JavaScript execution, and Google Analytics optimization.
