WP Rocket Review

Why should you use a caching plugin?

It makes everything much faster. Caching means that the content of your website is stored in a temporary file on a hard drive (of your server).

The main reason for doing this is that each time a visitor loads a page, WordPress and WooCommerce have to run a lot of code to generate the content of the page which takes a lot of time.

So when you cache your site, the content of the page is served from the file. And it's much quicker. This results in a decreased loading time for your visitors. And it usually leads to higher conversions and more sales. That's what you want.

WP Rocket - the best WordPress caching plugin

You have plenty of WordPress caching plugins, like WP Fastest Cache, W3 Total Cache, and Comet Cache to choose from.

But I think WP Rocket is the best caching plugin for WordPress. It's easy to use, it's fast, and it comes with all the features you need to get started. Plus, it has excellent customer support in case you need any help.

The main strength of WP Rocket is, that you don't have any extensive settings there. You just install it and you're good to go. The plugin optimizes everything on your website automatically.

This is a big thing, especially if you compare WP Rocket to its competition. If you look at a plugin like W3 Total Cache, you'll see that it has over 50 settings. And if you're not an expert, it's very easy to break your website when changing one of those settings. So WP Rocket is much faster to deploy. It takes care of everything in the background. Kudos to the developers!

How to install WP Rocket

Firstly you need to buy the plugin from the WP Rocket website.

Once you've purchased the plugin, there are two ways to install it - via WordPress or Manually from FTP.

If you want to install it directly from WordPress:

1. Log in to your WordPress dashboard and go to Plugins > Add New.

2. Select the plugin folder from the hard drive and click upload

3. Once the plugin has been installed, click on the Activate button to enable it.

Your copy of WP Rocket, downloaded from their site wp-rocket.me will automatically contain your license key inside. You can also manage your licenses in the wp-rocket.me dashboard.

How to configure WP Rocket

Now that you have the WP Rocket caching plugin installed, it's time to configure it. Basically, you have a few main areas here.


Here you take care of caching the site in general. You can choose which types of resources are cached and for how long.

If you would like to run the cache for logged in users or to have a separate cache for mobile phones.

If you have a WooCommerce store, I recommend also enabling Lazy Loading, as this will further improve the loading time of your pages.

File Optimization

Here you'll find settings that help optimize images and minify HTML/CSS/JavaScript files on your website.

You can enable these features individually, or let the plugin do this automatically for you.

The most stunning feature for me is "Optimize CSS Delivery". WP Rocket bot will scan your site and extract only CSS styles, that are used for the particular page. And then it loads them inline, in the head section of your page. So above the fold content is displayed to your visitors quicker. This is incredibly helpful in achieving a fast Google Pagespeed score.

The second most awesome feature is "Remove Unused CSS". Here WP Rocket bot will scan your site and remove all CSS styles, that are not used anywhere on the website. It's super useful because multipurpose WordPress themes are usually stuffed with a lot of universal CSS. And this is hurting your Google Pagespeed score.

Other settings

They are very well described in WP Rocket documentation, so I'm not going to get into detail about those.

Cache Preload and Sitemap Preload are self-explanatory. If you have a large website, these can help speed up the crawling of your site by search engines.

Database Optimization helps you clean up your WordPress database and optimize it for better performance.

CDN Integration allows you to connect your site to a CDN (Content Delivery Network) like CloudFlare or Stackpath.

Security helps you protect your website against malicious attacks.

Add-ons is where you can find integrations for popular WordPress plugins, like Yoast SEO and Gravity Forms.

That's it! As I was staging at the beginning - once you upload and active this plugin, there is not that much to configure.

How to check if WP Rocket is working

There are a few ways to check if WP Rocket is working. The first is to look at your page source code and see if there are any caching headers added. This can be done in Chrome Developer Tools for instance.

Another way is to run a speed test using a tool like Pingdom or GTmetrix. If the loading time and score of your website have improved significantly, then you know that WP Rocket is working.

How to turn off WP Rocket cache for a specific page

If you want to turn off WP Rocket caching for a specific page, you can do this by adding the ?nocache parameter to the URL of that page. For example: http://www.mysite.com/?nocache

Or you can set URL's, that should not be cached, in your WP Rocket settings.

How to clear WP Rocket cache

Clearing the WP Rocket cache is easy. Just go to the WP Rocket settings and click on the "Clear Cache" button. You can also clear the cache for a specific page by clicking "Delete cache only for this page", while being on that specific page.

How much WP Rocket cost

WP Rocket is a premium plugin and costs $49 for a single site license. However, there is a 30-day money-back guarantee so you can try it out risk-free.

If you want to use it on 3 sites, you'll have to pay $99. And for multiple sites, prices start at $199.

Overall, WP Rocket is one of the most feature-rich caching plugins on the market. It's easy to use and offers an incredible level of performance optimization that can help boost your website speed and visibility in search engines like Google. So if you're looking for a powerful caching solution, WP Rocket is definitely worth considering.

Should you buy WP Rocket?

To be frank, I have an unlimited license and I'm using it with all my clients. No matter how complex their WooCommerce stores are, I've never found a better plugin. You can simply plug&play it and be sure, it's not going to screw up your site.

These guys are doing a great job and they are constantly improving their product. And I think that $49 is a fair price for all the features you get.
