## What makes WP Rocket better than the other caching plugins?

WP Rocket integrates performance features such as deferred JavaScript loading, delayed JavaScript execution, LazyLoad, CSS delivery optimization, minification, CDN configuration, and cache preloading. While being complete, WP Rocket is also very simple to configure, even for beginners. WP Rocket also has its own self-hosted crawler bot that will visit your site and generate cached files so that when human visitors come to your website, they immediately get the fast, cached version of the page. If you have issues with the WP Rocket plugin, help documentation can be found in the [WP Rocket documentation](https://docs.wp-rocket.me/).
