Review: W3 Total Cache Plugin


WordPress Core is somewhat lacking when it comes to using caching systems to decrease site load time and use of server resources. Using a caching mechanism on the WordPress site ensure enhanced user experience by reutilizing the data user has already requested by making use of browser caching. Due to caching, files are instantly available which makes a website load faster.

Luckily, there are a few best plugins available in the WordPress repository; one of them is WordPress W3 Total Cache plugin that helps to make websites load faster using caching rules. W3 Total Cache is by far the most versatile WordPress caching plugin available, used in high traffic sites like Smashing Magazine, Mashable, MakeUseOf, and Yoast.

W3 total cache plugin can improve every aspect of your WordPress sites like its page cache, Minify, Database Cache, Object Cache, Browser Cache, CDN support, Varnish, and Network performance, etc. All these things make W3TC as one of the best-caching plugin for WordPress blogs.

What is caching?

A cache is an area in the computer’s memory that stores recently used information. When a site is cached, caching plugins save dynamically generated HTML files in the cache and serve them whenever a request is made instead of reloading the entire scripts from WordPress.


In simple terms, a cache is a time-saving device. As business owners, web administrators, and bloggers we are well aware of the speed limitations of our websites. Reducing file load times is a high priority for most of us but many people are not familiar with web cache software, which can significantly improve download speed on your site. Caching is an important part of WordPress SEO. We’ll examine the benefits of using one of the most popular cache tools for WordPress, W3 Total Cache.

Why do you need a Caching Plugin?

Speed is one of the most important factors used by search engines like Google to determine search rankings. Slower sites rank low, and fast websites rank higher. WordPress is written in PHP which is a server-side programming language. When a user requests a page from your website, WordPress runs PHP scripts to fetch the page and display it. This resource-intensive process is slow and becomes even slower when you are on a shared hosting environment. This can significantly reduce your site’s performance and search rankings.

A caching plugin stores a version of your pages in the cache. When a user visits your website, they are served the cached version. This eliminates the need for WordPress to run PHP scripts. Your site becomes faster and your server becomes more responsive.

Let’s have a look at one of the most used performance optimizer tools available for WordPress, W3 Total Cache.

W3 Total Cache

With more than 1 million active installs of this plugin, we can safely presume it does what it says on the tin: Increases server performance and reduces download times. W3 Total Cache is an open-source plugin, which is completely free to use. A free install gives you access to all of the features, and you won’t be pitched any upsells after the fact.

W3 Total Cache does the job of storing data from previous requests to prevent re-downloading of the same data for further requests. It also compresses elements of your page and creates static files before they are sent to the browser, reducing the overall page size and increasing the speed of WordPress.

The first thing you need to know about this plugin is that its Settings area is divided into 16 pages. W3 Total Cache has a dedicated Settings page for every type of caching – page caching, object caching, database caching, browser caching, etc. The level of customizability that you get with W3 Total Cache is difficult to find elsewhere. Even though it’s a popular choice, it may not be the best option for WordPress beginners. So unless you’re a developer who has lots of experience with these options, I’d recommend sticking to the defaults.

How W3 Total Cache Works?

W3 Total Cache is a plugin like any other. If you have an up-to-date version of WordPress, you can install and activate it from the admin panel. You’ll then need to spend some time setting up the following features.

  • Page Caching: Like WP Super Cache, W3 Total Cache serves static pages whenever it can. When you enable this feature, choose the method it will use to create the pages. A basic disk is probably fine. You can then configure what will be cached and how long the cached version will last before it expires.
  • Minify: W3 Total Cache can ‘minify’ HTML, JavaScript, and CSS files. This removes all whitespace in the files, making them smaller. This setting needs to be reviewed when you set up the plugin.
  • Database Caching: W3 Total Cache caches database queries, speeding up the site significantly. Make sure this doesn’t cause problems with your content.
  • CDN: Integrate W3 Total Cache with a range of CDNs, including StackPath, Amazon S3, Amazon CloudFront, or any CDN that accepts FTP uploads. You’ll have to set up the CDN separately.

If you have the time, setting up all of these features could be worthwhile.

Features List

The following are the many features W3 Total Cache Plugin can offer:

  • GZIP compression to optimize web browser rendering
  • Accelerated Mobile Pages (AMP) support

How to measure the plugin’s effectiveness?

When determining the effectiveness of this plugin, it’s crucial that you can correctly calculate and test your website’s page load time.

Statistically speaking, Neil Patel says that if the load time takes more than 3 seconds, 40 percent of people leave a website. So it comes as no surprise that Google’s search algorithm continues to prioritize site speed. The less time you spend on the load, the higher your search rankings, and the more organic traffic you can generate.
