How Does WP Rocket Work?

WP Rocket is a caching plugin that was created in 2012 by Jean-Baptiste Allard and Jonathan Buttigieg. It’s one of the most popular caching plugins available, with over one million active installations.

The plugin speeds up your website by caching your pages and posts so they can be loaded more quickly. When a user visits your website, WP Rocket retrieves the cached version of the page instead of loading it from scratch. This results in faster load times for your visitors.

WP Rocket also minifies your HTML, JavaScript, and CSS files to reduce their size. This allows your website to load more quickly, even on mobile devices. It also integrates with CloudFlare, Jetpack, and other popular plugins to provide even more performance enhancements.

The Benefits of Using WP Rocket

WP Rocket is a caching plugin that can be used on any WordPress site. It speeds up your website by caching your pages and posts so that they can be served to your visitors more quickly. This is especially beneficial for sites that receive a lot of traffic, or for sites that have slow loading times.

In addition to speed, WP Rocket also provides other benefits. These include, but are not limited to:

  • Minimizing the amount of time it takes for your website to load
  • Preloading your pages and posts so that they’re ready to be served when a visitor requests them
  • Caching your images and videos so that they’re served more quickly
  • Compressing your files to reduce the size of your pages and posts
  • Enabling browser caching so that static files are stored in the visitor’s browser and don’t have to be downloaded each time they visit your site

Overall, WP Rocket is an excellent caching plugin that can speed up your website significantly.

WP Rocket features and dashboard

One of the most brilliant aspects of WP Rocket is that it integrates simplicity and accessibility with a bevy of essential performance adjustments to boost your website’s speed. This can all be done swiftly without any configuration – simply activate the plugin and you’ll instantly enjoy an accelerated loading WordPress site without having to make any changes!

The features that WP Rocket activates right away are:

  • Page caching
  • Browser caching
  • GZIP compression
  • Cross-origin support for web fonts

WP Rocket

With WP Rocket, you can rest assured that your website will be optimized for optimal performance. This smart caching plugin automatically detects common plugins, themes, and hosting environments to ensure optimum compatibility while also automatically configuring itself to work optimally in all of them! For example, if you have a WooCommerce store running on your site, then this clever tool will detect that and disable caching capabilities around the checkout page to prevent any issues.

From there, WP Rocket offers an intuitive dashboard where you can configure a host of other performance optimization techniques and fine-tune how your site’s caching functions. Let’s take a look at all the options!

Basic cache settings

WP Rocket

At first, you can choose to turn to cache on for mobile visitors and select a separate cache if so. Utilizing this approach is advantageous if your website offers its own unique mobile experience and wants to ensure that only those patrons receive the customized version of it.

You can decide whether or not to enable caching for logged-in WordPress users. If you opt-in for public registration like a membership site, enabling this feature is an excellent way to expedite the performance of your website – by default WP Rocket removes logged-in users from its cache so that they never see a cached version of their site.

With these options at your disposal, you can configure the cache lifespan, which dictates how long the site holds an individual page’s cache before expunging it. If the content remains static or rarely changes over time – for instance, if your website is built around a single product offering – then an indefinite cache life may be suitable. Alternatively, in instances where content on your website is likely to change often and frequently – perhaps due to seasonal fluctuations or new products being added – you might want to purge caches every X minutes/hours/days depending on what suits best for each set of circumstances.

Remember – WP Rocket’s advanced caching capabilities offer plenty of ways to optimize your site, enabling you to make truly dramatic improvements in page speed and Web Core Vitals. Let’s explore those features that can really move the needle on performance!

File optimization

The File Optimization tab houses a bevy of features to aid in the optimization of your website’s CSS and JavaScript files. Generally speaking, WP Rocket has been exceptionally ambitious with its array of enhancements; including unparalleled functionality such as minification capabilities for JavaScript and CSS files that are typically found in other performance plugins. It’s rather remarkable to see such novel approaches when compared to standard options! With 3.9 we have witnessed two exclusive additions – both being quite distinct from what is presently available within this space:

File optimization

  • Removed unused CSS – This feature will scan your site and remove unused CSS on a page-by-page basis. In testing, I’ve found that this feature alone can typically reduce the file size of a page by 80-100 KB, though it depends on the theme and plugins that you’re using.
  • Delay JavaScript Execution – This feature lets you delay loading JavaScript files until a user interaction (e.g. click or scroll). This speeds up initial load times and especially improves your Largest Contentful Paint time (which is key for Google’s Page Experience update). You can also manually exclude certain files to make them load right away if needed.

WP Rocket has long been offering the delay JavaScript execution feature. However, before you could only manually define files to include/delay using its previous iteration; a process that was quite time-consuming and prone to error. With WP Rocket 3.9 an all-new automatic system is in a place where by default WP Rocket enables this excellent functionality for all javascript files – leaving users with the option of opting out if they wish or individually selecting which ones should be disabled via their preferences panel.

File optimization

  • Minification – Eliminates wasted space in your code files to shrink them without changing functionality. For example, removing white space and code comments.
  • Concatenation – Combines multiple files into one file to reduce the number of HTTP requests your site needs. Personally, I no longer enable this as combining files isn’t that helpful if your server uses HTTP/2 (which many hosts do now). Additionally, you won’t be able to combine JavaScript files if you use the delay JavaScript execution feature.
  • Optimized loading – By optimizing CSS delivery and implementing deferred JavaScript loading, you can avoid the “eliminate render-blocking X” problem in Google PageSpeed Insights.

Media optimization

The Media Optimization tab assists you in optimizing your sites’ images, videos and iframe embed by enabling lazy loading. When this feature is enabled, the site will refrain from displaying content below the fold until a visitor begins scrolling down their page.

Media optimization

By compressing the initial load of your site, WP Rocket alleviates the burden on your server and thus speeds up perceived page load times. Moreover, you can utilize this handy feature to swap out YouTube embeds with static thumbnails that direct users to click on an image for further interaction.WP Rocket can also help you disable emojis and WordPress embeds

Cache preloading

Cache preloading, which can be arranged in the preload section of your configuration page, is a more advanced topic – but it’s invaluable for optimizing your website’s cache. With most caching plugins’ functionalities, a visitor’s first access to content only occurs once they visit its corresponding web page; thus after that initial cache clears – subsequent visits will not result in obtaining an already-cached version of the webpage. Consequently, this could lead to a sluggish browsing experience as compared with other users who have visited prior content and whose caches remain intact.

Traditionally, one way of resolving issues with WPRocket is to preload content into the cache. Yet, due to its considerable benefits (e.g., alleviating loading times for visitors), it’s often overlooked as a viable solution that could potentially yield optimal results in terms of user experience and performance optimization.

Cache preloading

To this end – Cache preloading can be activated so that WP Rocket automatically loads any new or updated content whenever you publish it or update an existing post; likewise ensuring your homepage and all links on display are also always precached – even before users have had an opportunity to visit!

Beyond that, you can also enable sitemap-based preloading, which allows you to automatically preload the content in your XML sitemap whenever settings or cache lifespan changes.

Advanced rules

Advanced rules

For those who are casual users of caching, the Advanced tab is unlikely to prove particularly useful. However, advanced users and developers will find it a veritable treasure trove – they can fine-tune how their caches function, including targeting specific URIs; cookies, and user agents for exclusion or even specifying URLs that should always be purged when content gets updated.

Database optimization

To optimize your WordPress site’s database for speed and efficiency, you can employ the Database tab to remove any extraneous data such as trashed posts, spam comments, or other obsolete content from it. This process is known as purging; selecting an automatic frequency will automate this feature so that maintenance of your site remains efficient while keeping tabs on things.

Database optimization

There are three options available: daily – purges every day at specific hours between midnight and 8 am hourly – purges once per hour on a predefined schedule daily-scheduled-purge enables you to customize when the process occurs

CDN integration

Utilizing a content delivery network (CDN) can help you achieve optimized global page load times by sending your static files from a decentralized infrastructure of servers distributed across the globe.

CDN integration

WP Rocket can help you use a CDN in two main ways:

  • WP Rocket now offers its own premium CDN service called RocketCDN that you can easily add to your site.
  • WP Rocket lets you connect to any third-party CDN service if you’d prefer to use a different service.

The WP Rockets RocketCDN service is a highly enticing proposition for sites experiencing high levels of traffic. Powered by StackPaths’ global network, it offers an array of 45+ edge locations across the world – providing unparalleled reach and speed!

However, unlike StackPath, RocketCDN is not billed based on your usage. Instead, you’ll pay a flat $7.99 per month per site for unlimited bandwidth. It’s pretty rare to find a CDN that offers unlimited bandwidth, so this can be a great deal for high-traffic/bandwidth sites (though not for low-traffic sites).

With its one-click setup provided by WP Rocket, rocketing up your speed and increasing the performance of your WordPress website is as simple as one-two-three. Nonetheless, equipping yourself with technical acumen may be required in order to successfully complete this task – shouldn’t it be an easy endeavor when all you have to do is follow a few steps?

If you want to use a separate CDN service, WP Rocket can also help you rewrite some/all of your site’s static content to use the CDN URL – e.g. cdn.yoursite.com. You can also:

  • Choose what type of files to apply the CDN to – all files, images, CSS AND JavaScript, just CSS, just JavaScript.
  • Exclude specific files from being served via the CDN.

For high-activity, bandwidth-demanding websites, I’d highly recommend taking advantage of the capabilities offered by RocketCDN. However for those with lower traffic levels and/or a need to economize on their hosting costs; it may be prudent to utilize an alternate CDN service such as KeyCDN or BunnyCDN for more affordable options.

Heartbeat Control

The WordPress Heartbeat API enables you to remain in contact with your site, ensuring that it is up-to-date at all times. It offers numerous benefits, such as auto-save drafts to safeguard against losing work and synchronization between the browser and server – goals we can all appreciate!

Nonetheless, the incessant din of this cranking device can overwhelm your server resources, placing undue strain on CPU utilization and compromising system performance.

Heartbeat Control

For that reason, a lot of people like to either:

  • Completely disable the Heartbeat API.
  • Change how frequently the API sends requests, to limit the impact while still getting some of the benefits.

Built-in add-ons

Ultimately, the Add-ons tab features WP Rockets pre-installed integrations. These tools allow you to host Google Analytics and Facebook Pixel tracking scripts locally – but they were taken out of service with the release of WP Rocket 3.9 as those capabilities have now been superseded by its novel delay JavaScript execution feature. Nonetheless, WP Rocket still offers supplemental features to facilitate connections with three prominent services – Xobni, Anchorfree Cloud, and Kaltura.

  • Varnish
  • Cloudflare
  • Sucuri

For instance, enabling the Cloudflare integration opens up a new Cloudflare area where you can connect your site with ease and exert some basic configuration options from within your WordPress dashboard. Additionally, it is possible to delete the cache associated with WP Rocket whenever it is purged – thus giving you complete control over its functionality!

Pricing and Licensing Options for WP Rocket

When it comes to pricing and licensing options, WP Rocket is surprisingly affordable. They offer two plans to choose from, with the single-site plan starting at just $49 per year. This plan also comes with a 14-day money-back guarantee, so you can try it out before you commit.

WP Rocket price

The multi-site plan starts at $99 per year for three sites, and if you need more sites, there’s an additional fee of $49 per site per year. So if you have 10 sites, the total cost would be $248. No matter which plans you choose, all WP Rocket licenses come with one year of updates and support.

The great thing about WP Rocket is that it includes a ton of features that other caching plugins don’t have (like white-label branding). And considering the low cost of a one-year license, it’s really hard to beat.

Comparing WP Rocket to Other Plugins

When it comes to caching plugins, there’s no shortage of options out there. And while WP Rocket might be the most popular plugin, it’s also important to consider other alternatives. So let’s compare WP Rocket to two of the most popular plugins: W3 Total Cache and WP Super Cache.

WP Rocket has better performance than both plugins, as evidenced by its significantly lower page load times. Additionally, its user-friendly interface makes it easier for novice users to get up and running quickly.

W3 Total Cache is for more experienced users who want more control over their cache settings. It offers more features than WP Rocket, including minification and Gzip compression. However, the plugin can be quite complex and difficult to configure correctly.

WP Super Cache is another popular plugin that’s known for its simplicity and straightforward setup process. It doesn’t have as many features as W3 Total Cache or WP Rocket, but it offers decent performance and can be a good choice if you’re limited on a budget or just want something basic and quick to set up.

Is WP Rocket Right for Your Website?

Alright, so now that you know more about WP Rocket, you’re probably wondering if it’s the right tool for your website. The answer, of course, depends on your specific needs.

If you need a plugin with a lot of advanced features and customization options, then WP Rocket might not be the best fit. The plugin is designed to be lightweight and easy to use, so it’s missing some of the more powerful features.

On the other hand, if you’re looking for a simple caching plugin that can get the job done quickly and easily, then WP Rocket is definitely worth considering. The plugin is incredibly easy to set up and use, and it’s been proven to deliver great results in terms of speed and performance. Plus, its intuitive dashboard makes it easy to make further tweaks to optimize your site.

WP Rocket Pros And Cons

Despite its relative youth, WP Rocket boasts an enviable array of advantages. Among them are the only caching plugin we were able to find with sufficient attention paid to many crucial adjustments that must be made in order for Core Web Vitals inspection standards to be met. Add this potent acceleration capability and you’ve got a winning combination!

However, WP Rocket is not without fault. It can be costly at a time when there are many free options available; while its value proposition is apparent for some sites, it still lacks some of the features one might expect to pay $49 per annum for – such as image optimization (unless an upgrade is purchased on Imagify), and no form of script management capabilities.

Both of these are important for passing the CWV. And WP Rocket doesn’t cover them, at least at the time of writing.


  • Powerful plugin to speed up your site
  • Tons of minor tweaks that can help your WordPress site pass the CWV
  • Quality of life tools
  • Great integrations
  • Easy to use / not confusing interface


  • Pricey
  • It doesn’t have all the features you’d expect for a paid caching plugin


In short, WP Rocket is a powerful caching plugin that can speed up your website significantly. It’s easy to use and comes with a host of features to help you optimize your website for speed. If you’re looking for a way to speed up your website, WP Rocket is definitely worth considering.


Is WP Rocket Worth The Money?

For larger and medium-sized websites that require some finessing to attain Core Web Vitals, WP Rocket is an invaluable investment. It offers features such as excising files from minification or discarding unused CSS – which can be beneficial for any site of moderate size.

What Does WP Rocket Do?

WP Rocket is a feature-rich plugin that allows users to improve the performance of their WordPress website and to achieve Core Web Vitals scores in no time. Through its customization options, users can configure caching and minification settings as well as preloading functionality – all without requiring any intervention on their part!

Which Is Better, WP Rocket Or W3 Total Cache?

A W3 Total cache is a fantastic option if you’re on a budget. However, if you want to get advanced features that you wouldn’t get in free caching plugins, WP Rocket is the way to go. It’s the safest bet you’ll pass the Core Web Vitals.

Is WP Rocket A Free Plugin?

WP Rocket is a paid plugin. At $49/year, it remains its most expensive competitor – even if one has access to the 14-day refund policy of other plugins. But with this guarantee in place, users can experiment and test its efficacy without risking losing any funds upfront!
