WP Rocket is one of the most popular caching plugins for WordPress. It is designed to increase the speed and optimise the performance of websites. Here are the highlights of WP Rocket:   Caching: WP Rocket dramatically reduces your website load times by caching on the server and in the browser. Caching enables faster serving of web pages because content is retrieved from a pre-built cache.   File Compression: Reduces file sizes by compressing CSS, JavaScript and HTML files. This makes your website load faster and improves the user experience.   Image Optimisation: WP Rocket automatically optimises images, reducing file sizes and increasing the loading speed of web pages. This allows users to navigate your website faster. Delayed Loading Images: Images on web pages load as the user scrolls down the page. This reduces the initial loading time of the website and improves the user experience.   Page and Browser Caching: WP Rocket prevents users from downloading the same content over and over again by caching your website’s pages and browsers. This allows the website to load faster. Code Cleanup: WP Rocket cleans your website code, eliminating unnecessary or unused code. This makes the website load faster and improves its performance.
