Three seconds.

That's all your visitors give you when they come to your website. If your website takes longer to upload, 40% of users will give up on it.

What's worse, delaying the page response by a second can result in a 7% reduction in conversions. You end up losing 40% of your website traffic, 80% of which these people will never return.

I could keep talking about those scary load time stats, but the bottom line is that your website has to be fast if you want to increase your traffic and conversions. If you don't work on improving load times, you lose hundreds of thousands of dollars every year.

Fortunately, there is a solution: install a WordPress cache plugin.

These plugins are designed to improve the speed of your website by instructing the server to save some files to disk or RAM depending on how it is configured. After that, the plugin will remember the content it provided in the past and duplicate it.

The result? Faster webpage loading.

# 3 – W3 Total Cache – The best for seasoned developers

W3 Total Cache is hands down one of the best open source plugins for WordPress caching that offers an out of the box and advanced caching mechanism. While it is full of features, it is also a bit complicated, especially for users who lack technical skills.

The plugin is compatible with most hosting plans including shared, dedicated, and VPS server hosting. Since it's free, you can use all of its features after installing the plugin – no upsells to worry about.

It can improve your server performance by caching every aspect of your website and integrating it with multiple content delivery networks.

Developers in particular like this plugin as it offers up to 80% bandwidth savings without affecting other website elements thanks to its collapse function, which reduces the size of HTML, JavaScript, CSS and feeds.

# 4 – WP Super Cache – The best for customization

When a plugin has more than two million active installs, you know the developers are doing something right.

WP Super Cache was developed by Automattic, the same people who gave you Jetpack, Akismet, and WordPress.com. It's as popular as a plugin, and not without reason.

The plugin generates static HTML files from your dynamic WordPress content. You also save a lot of bandwidth and shorten the loading times of pages because the web server provides the lighter HTML files instead of the extensive PHP scripts.

WP Super Cache also gives you three caching modes: simple, expert and WP cache caching.

Of the three, expert mode is the fastest, but you'll need to modify the .htaccess file, which requires coding and web development experience. However, if you have the technical know-how, you can adjust the plugin settings to improve functionality.

You can use WP-Cache-Caching mode to cache content for known website visitors. Because of this, caching mode is ideal for websites whose users can normally be logged in, leave comments, or view custom content.

You don't have any experience in web development? Don't worry, you can use the simple mode where all you need is a custom permalink. Since the setting is easier to configure, you don't need to change your .htaccess file.

Plugin functions

  • Page caching
  • Content Delivery Networks (CDN) support
  • Caching for visitors with a mobile device
  • Browser caching
  • Scheduler to manage deletion and re-caching at specific intervals
  • GZIP compression


WP Super Cache is available for free.

You can choose to have the CSS and JS files deleted at a later date.

WP Fastest Cache effectively implements WordPress' broader caching to reduce page load time for returning visitors. In addition, several CSS files are combined into one in order to reduce the number of HTTP round trips. If necessary, you can also disable emojis on your website.

What I looked at to find the best WordPress cache plugin

I'm not going to gloss it over: Choosing the best WordPress caching plugin isn't the easiest task on your list.

Aside from names that sound similar, most of them offer similar functionality in different ways. Therefore, if you use two or more at the same time, they can conflict. The fact that caching is technical also means that you need to be practically an expert to make the right choice.

I've already listed my top five tips for the best WordPress caching plugins, but I want you to know how I came to this decision.

Let's take a look at the factors to consider when looking for caching plugins for WordPress.

CDN support

CDN stands for Content Delivery Network, a network of data servers that renders cache data for web users from a server near them.

Whenever the traffic on your website increases, so does the processing activity of your web hosting server. This leads to a decrease in your website's page loading speed.

This is the exact point where CDN comes into the picture.

Please wait. This is where things get a bit technical.

When you use a CDN, static data from your website is cached on each server in the CDN. When a user requests a page on your website, they get a cached copy from a server closest to the user, avoiding delays.

Because of this, you should make sure that your potential caching plugin supports the CDN you are using. If not, you may lose visitors.

Browser caching capability

Browser caching stores CSS, logo, and other resources that are typically downloaded when a visitor opens your website. This feature allows you to decide how much of your webpage to cache on the user's device, making you independent of the user's browser cache settings.

Look for options that will allow you to set the length of time that the downloaded content will be kept on the user's system.

However, I would not recommend setting the time that the content should be cached for more than six months as this can result in the user receiving web pages that are not updated.

Exclusion of assets and pages

While many WordPress websites are purely static content, some also contain dynamic content. This can include a membership website, an ecommerce website with WooCommerce, a website with courses, and so on.

The catch is that dynamic content doesn't work well with browser caching and page caching. Hence, it is wiser to look for a caching plugin that will allow you to exclude certain pages and assets from caching to avoid glitches.

Customer service

If you are new to the world of caching, this is probably your first time hearing most of the terms discussed above.

Because of this, you should make sure that the plugin developers have efficient customer support that can help you if you get stuck with the daunting caching setup. If you find that a premium caching plugin offers better support, I would recommend choosing this over a free option.

After all, your peace of mind should always be a top priority.


Website speed is incredibly important to the success of your website. If you don't use a caching plugin now, you are already one step behind your competitors.

See customer reviews and do thorough research before choosing a plugin for your website. I've done my best to include options that are packed with features and will give you the best results. However, you can always opt for other caching plugins that you think will give better results.

In the end, the goal is to cut those load times down and make your website super fast.
