WP Rocket Features & Settings that Powers Your Website Speed and Performance Optimization

1. Caching 

WordPress is a dynamic CMS. It fetches data from the database every time a user visits your website which makes your website load slower. 

WP Rocket solves this problem by creating a static version (cache) of your website until the new changes come up. 

It handles cache at multiple levels – 

1. Single Page Caching 

Page caching refers to the process of creating a cached version of a particular page. 

This wordpress caching plugin lets you clear and creates a cache of an individual page as well as for all pages simultaneously.


The plugin adds a menu to the WordPress admin bar from where you can clear a page cache for a particular URL. 

2. Bulk Caching 

You remove and regenerate cached files for all the pages and posts in a single click from the dashboard.


3. Mobile Cache 

The mobile speed of a website becomes significant especially after the release of Google’s mobile-first index.


Well, this WordPress performance plugin allows you to create separate cache files for mobile devices that speed up your site for mobile visitors. 

4. User-Specific Cache

You can create a user-specific cache by creating separate cache files for logged in and not logged in users.


This feature is pretty handy when you have user-specific content on your website.

For example – A membership website or a website where a user must log in to see the content.

2. Cache Preloading

This WordPress speed optimization plugin automatically generates the cache whenever you add new content or updates existing content. 

1. Cache Preloading Manually 

You can also trigger cache preloading manually via – 

1. WordPress Admin bar


2. WP Rocket Dashboard


2. Sitemap-based Cache Preloading

By default, WP Rocket starts cache preloading with the links on your website’s homepage and then the sitemaps mentioned in the settings.


It automatically detects if your website sitemap is generated by Yoast SEO, All-in-one SEO, Rankmath SEO or The SEO Framework. 

For other sitemaps, you can specify the sitemap URL in the text under the heading – Sitemaps for preloading. 

3. Prefetch DNS Requests

DNS Prefetching is used to load third-party resources faster, especially on mobile devices and networks.


WP Rocket lets you prefetch third-party resources.

All you need to do is to add those resource URLs in the textbox under the heading Prefetch DNS Requests. 

3. Render-blocking Javascript and CSS

What is render-blocking JavaScript and CSS?

In simple words, render-blocking resources are those JS & CSS files that are requested from the server while rendering a website. 

Google Pagespeed Insights tools throw an error – Eliminate render-blocking JavaScript and CSS in above-the-fold content.

It becomes difficult for both technical and non-technical users to find the solution for this error. 

WP Rocket offers 2 solutions for this error. 

1. Optimize CSS delivery


Check the Optimize CSS delivery option it will handle everything. 

2. Load JavaScript deferred


Just like CSS files, you can optimize avoid render-blocking JS files by enabling load javascript deferred option. 

4. File Optimization – Minification & Concatenation

File Optimization is one of the powerful features of WP Rocket. 

Below are the file operations which boost up the website performance and improves page speed and GTMetrix scores.

1. File Minification (HTML, CSS, JS) 

This WordPress speed optimization plugin minimizes HTML, CSS, and JS by removing unwanted whitespaces, comments, and line breaks which ultimately reduces file size. 

File minification results in reducing server load which makes your website load faster. 

2. Combining Resources (CSS, JS, and Fonts)

WP Rocket offers file concatenation for CSS, JS, and even Google font files. It combines multiple files into one to reduce the number of requests. 

Combines Google Fonts Files to Reduce the number of HTTP Requests


Merges All CSS Files into 1 to Reduce the number of HTTP Requests  


Combines JS Files (Internal JS, third-party JS, and inline JS) to Reduce the number of HTTP Requests


Optimized CSS Delivery to avoid render-blocking CSS & JS. 

I’ve already discussed delivery optimization for CSS in the above point. 

5. Media Optimization

WP Rocket offers 2 optimizations for media files – 

1. Inbuilt Lazy Load Functionality for Images, iFrames & Videos 

Image optimization is as equal as CSS and JS files optimization. 

70% (or above) files are media files like images and videos in almost every blogging, eCommerce, or business website. 

Therefore, WP Rocket plugin offers inbuilt lazy load functionality for images, iframes, and videos.


2. Disable Emoji & WordPress Embeds

On the other hand, it also lets you disable Emoji and WordPress Embeds which prevents the loading of extra files that are not getting used on the front end. 

Because people rarely use emoji in their blogging or business website. 

6. Database Optimization

Database optimization is one of the unique and powerful features that WP Rocket offers. No other cache plugin offers this level of database optimization. 

It cleans up or frees up the database by removing data that takes unnecessary space which results in an ultimately fast response of database queries.

Below are the database optimizations this speed booster plugin offers – 

1. Posts Cleanup (Revisions, Autodrafts, Trashed)

The plugin removes post revisions, trashed posts, and auto drafts which not only optimize the WordPress database!

But also cleans up unused data but also increase your database query search response. 


2. Comments Cleanup (Spam & Trashed)

Cleans up spam and trashed comments that take unnecessary space even after you marked them as trashed and spam.


3. Transients Cleanup (Temporary Options)

Well, there is no harm or setting loss even if you remove these options as plugins automatically regenerate these options if they require them. 


4. Database Cleanup (Table Optimization)

No matter how small the page on your website is. Database operations are always going to happen when someone opens up your website page. 

At some point, it increases the overhead of database tables. WP Rocket lets you reduce this database tables overhead by optimizing database tables.


5. Automatic cleanup (Schedule Cleanup)

WP Rocket lets you schedule automatic database cleanups to maintain your website optimization.


7. CDN Integration

One of the important factors in a website’s optimization is CDN (Content Delivery Network). 

WP Rocket lets you integrate your CDN with your website to maintain optimization.

Also, if you use Cloudflare or Sucuri as your CDN services, you don’t need to add them here. 

WP Rocket provides a dedicated addon for them.


8. Integrations

Apart from the above amazing and handful settings and optimization techniques, WP Rocket offers 5 add ons to extend its optimization reach.

1. Google Analytics


WP Rocket optimizes third-party Google Analytics tracking script by hosting them locally on your server. 

It helps in improving the page speed score in Google PageSpeed Tool and GTMetrix.

It stores Facebook pixel code on your website server to maintain caching policy effectively for third-party resources. 

3. Varnish


WP Rocket lets you purge varnish cache directly from your WordPress dashboard. 

4. Cloudflare CDN

WP Rocket lets you integrate the Cloudflare account with your website within the WordPress dashboard.

My Recommendation – Is WP Rocket Worth Paying?

As a WordPress developer, I personally found WP Rocket an amazing caching plugin for WordPress websites that combines multiple features that other cache plugins offer in ONE..!!

From the detailed WP Rocket review described above. You would agree too.

Of course, you can achieve the same by installing multiple plugins for different functionalities on your website.

For example – 

  1. You can use free WP Rocket alternatives like WP Super Cache and WP Total Cache for caching.
  2. WP-Optimize for database optimization
  3. BJ Lazy Load for image lazy loading. 
  4. Autoptimize for file minification and concatenation.
  5. And many others. 

But they are going to take more time for configuration. 

WP Rocket probably is a better option that provides everything above in a single monster package.
