WP Rocket does not provide a free edition, there are three types of plans that you can choose according to your needs: Single, Plus, and Infinite. Single can be used in only one domain, Plus can be used in three domains, and infinite can be used in unlimited domains.

Sometimes you can see web hosting providers with WP Rocket included in their hosting plan, however, it is unauthorized. WP Rocket indicated that they have no cooperative relationship with any web hosting providers. Therefore, if a host indicates that the WP Rocket plugin is included, you must pay extra attention. It is recommended to purchase the plugin on the official website if you need it.

WP Rocket plugin settings

1. Cache

  • Mobile device cache

    This is an option that is recommended to be selected. Nowadays, the traffic on the internet is mostly from mobile devices (e.g. mobile phones, tablets, etc.).Visitors will be reading the contents of the WordPress database directly if this option is not selected. Although the latest information can be read, the page loading speed will slow down.

  • User cache

    “Create a cache for logged-in users”. Select this option only if you are operating an e-commerce website and will have a large number of users to log in to the website or when there are many website administrators.

  • Cache life cycle

    Use WP Rocket’s default value of 10 hours. This can be regarded as the time to automatically clear the cache data. WP Rocket also has a manual clear function, which can clear the cache at any time.


2. File optimization

  • Minify CSS files

    Remove unnecessary parts of the CSS file, make the CSS file smaller, and improve the web page loading speed.

  • Minify JavaScript

    The principle is the same as compressing CSS, removing unnecessary parts from JavaScript files, making JavaScript files smaller, and improving web page loading speed.

  • Load JavaScript Asynchronous

    Asynchronous means that the website can execute more than two projects at the same time, avoiding that the website only executes a certain project and drags down the overall website loading speed.

  • Delay JavaScript execution

    It will allow some JavaScript to be executed after the user has executed some responses, and delay the loading of some non-essential JavaScript elements, which can make the website load faster.


3. Media

  • Enable for LazyLoad images

    Enable for iframes and videos (and replace Youtube iframe with preview image), the above option is to delay the loading of the image or video on the page until the website visitor scrolls to the position where the image or video needs to be displayed, which can improve the loading speed of the page, which is important for SEO and users experience.

  • Image Dimensions

    Add missing image dimensions. Select this option and the size of the image will be automatically defined to prevent the page displacement from affecting the website visitor’s loading speed and the CLS score.

  • WebP compatibility

    If there is a special conversion for website pictures into WebP format files with smaller capacity and faster loading, or some WordPress plugins automatically convert website pictures into WebP format, you can enable this option, WP Rocket will also create a cache for WebP files.
