Easy to setup Wp Rocket

Installation is as easy as can be. Once you’ve purchased and downloaded the plugin you can head to the Plugins section in your dashboard and click Add New. From here you can upload the downloaded file straight into your site. Once uploaded it will show up in your plugin list from where you will activate it.


Once activated you will find that under the Settings section you have a new section called WP Rocket. The next step is setting up the plugin to optimise the site.

Once you have opened WP Rocket you will find 7 tabs; 4 for options and 3 for support and documentation. One thing you will notice throughout these tabs are the instructions that are given with every option, except those that are self explanatory of course.


Starting with Basic Options you’re given a list of the most basic options you can set to optimise your site. Firstly you’ve got Lazyload, whereby the images on your page are only loaded when visible. The images further down the page will be loaded only when the user scrolls down that particular page.

Next is Files Optimisation; this constitutes the minification and concatenation of HTML, CSS and JS files. Following this you find Mobile CacheLogged In User Cache and SSL Cache; all simple options that depend on your own preferences.

Finally you’re given an option to set the Clear Cache Lifespan time. This is the time you want the cache to be stored in the browser after being created, before it gets removed and reset.

The Advanced Options tab opens as is shown in the screenshot above. Under this tab you will find options to Prefetch DNS Requests, Empty  the Cache of particular pages when updating a post, an option to Never cache a particular set of pages and an option not to cache pages that use particular cookies. All these options are self explanatory and have informative tips and video links beneath them to help you out even further.

Besides those you’re also given the options to select CSS files to exclude from minificationJS files to include in the footer during the minification process and JS files with deferred loading. Explanations and warning signs are once again given to help guide you in your selection
