When It Makes Sense to Invest Into a WordPress Cache Plugin

WordPress cache plugins speed up website loading times, improve SEO, and increase conversion rates. 

If your website pages take more than two seconds to load, it’s time to invest in a cache plugin. Loading times over the two-second mark are too long and will cause visitors to jump to another site. 

Some websites aim for a page loading speed of half a second. This is a good goal to strive for and is achievable with a plugin. However, if your website already has loading speeds under two seconds, it is not mandatory. 

Search engines like Google love fast websites. If you have SEO optimized your articles but are still not seeing them on the first page of a search, it may be because your website is too slow. Invest in a cache plugin if your articles are not near the top. If your SEO-optimized articles are consistently ranking at the top of Google, a cache plugin probably isn’t necessary.

According to a study by geckoboard.com, conversion rates across industries average between 2.35% and 5.31%. If your site is consistently seeing conversion rates below 2%, a cache plugin will help boost this number.

If you’re experiencing higher conversion rates, a cache plugin may not be necessary. It’s important to do research on average conversion rates for your specific industry to determine if your site is keeping up. 

#1 – WP Rocket — The Best for Most

WP Rocket

Best for Most

WP Rocket is trusted by over 1.6 million users and integrates with 99% of web hosting companies. Plus all three of its plans are under $250 annually. It’s the clear winner for the widest range of people!

WP Rocket is the best WordPress plugin for most. It is currently used on over 1.6 million websites and is advertised as the most powerful caching plugin on the planet. It’s great for eCommerce, bloggers, freelancers, and agencies, but it is effective on websites of any type. It’s compatible with top managed WordPress hosting and the most popular plugins and themes.

Once users download WP Rocket, they can immediately get their web pages cached. This will result in a faster website, boosted SEO, and increased conversions. Whenever users make changes to their site, the plugin automatically preloads the cache. It comes with browser caching which stores images, CSS, and JS into the navigation device’s local memory. 

For eCommerce owners, WP Rocket helps their websites run more smoothly without interfering with the purchasing process. The tool can exclude any pages from the cache so users can leave sensitive data untouched. Regarding GZIP compression, web pages can be decompressed in the browser and compressed on the server. 

WP Rocket integrates with 99% of hosting companies including Bluehost, GoDaddy, Kinsta, DreamHost, and WP Engine. It works with page builders and themes like Astra and Elegant Themes. Yoast SEO, WP Forms, Gravity, and Jetpack are some of the popular plugins it works with. It is also compatible with multilingual software and ecommerce stores like WooCommerce. 

WP Rocket has three pricing plans called Single, Plus, and Infinite. Its Single plan is for users with only one website and costs $49. Plus is for three websites and costs $99. Infinite has no cap on the number of websites and costs $249. All plans come with one year of updates and support. This plugin comes with a 14-day money-back guarantee

#2 – W3 Total Cache — The Best for Advanced Developers

W3 Total Cache Logo

W3 Total Cache

Best for Advanced Developers

If you’re an experienced developer who likes to tinker with your plugins and create a highly customized experience, W3 Total Cache is for you. It’s got the most advanced features on this list, and it’s free to get started.

W3 Total Cache is a more complex WordPress cache plugin and it’s the best tool for experienced developers. Unlike other caching plugins, it does way more than simply reduce bandwidth and load consumption for HTML pages. It has a multitude of advanced features, and it’s the only plugin designed to optimize all practical hosting environments regardless of size.

When fully configured, this tool guarantees at least 10 times overall site performance improvement. Users can see up to 80% saving in bandwidth when they minimize JS, CSS, and HTML files. Its optimized progressive render feature allows pages to be interacted with more quickly. The tool comes with instant repeat page views and browser caching. 

W3 Total Cache is compatible with virtual private networks, shared hosting, clusters, and dedicated servers. It includes caching of web pages, feeds, search results, CSS, JavaScript, objects, fragments, and more. Users can use the Lazy Load feature to defer offscreen images and use one of several content delivery network (CDN) integrations to optimize images. 

W3 Total Cache has over one million active installations, is available in 16 languages, and is free to use. This tool is great for developers who know what they’re doing, but some features including the CDN integrations may be too advanced for some users. If you are unfamiliar with how caching plugins work, we recommend going with a simpler option. 

W3 Total Cache is free to use, but it also boasts a premium version for $8.25/month (billed annually). 

#3 – WP Super Cache — The Best for Multiple Caching Modes

WP Super Cache

Best for Multiple Caching Modes

If you want to switch between caching modes, look no further: WP Super Cache has three of them. It also auto-deletes out-of-date cache files, so you don’t have to do it manually. Best of all, it’s free!

WP Super Cache is a tool with three distinct caching modes that are varying in speed. Expert mode is the fastest, Simple is the recommended mode, and WP-Cache is slightly slower but fits a specific need. 

Users can set the plugin to Expert mode to completely bypass PHP and see extremely fast speeds. However, it requires more customizations, and Simple mode is a better option if you are inexperienced. 

Simple mode is slightly slower than Expert mode, but it is easier to configure. Users can still keep parts of their page dynamic in Simple mode. WP-Cache mode is for URLs with feeds and for parameters with cache pages for known users. It is the slowest mode, but it is the most flexible of the three. 

WP Super Cache comes with automatic garbage collection which deletes out-of-date cache files. Users can customize the scheduler option to set up how often a garbage collection occurs. Users can set when a file becomes stale by customizing cache timeout. 

This feature includes automatic notification emails that inform users when stale files are deleted. The tool allows users to serve static files like images, CSS, and JavaScript files through CDNs to speed up site loading times. 

WP Super Cache is available in 28 languages and has over two million active installations. One thing to watch out for is the support seems to be lacking. As of writing, only 5 out of 45 support issues have been resolved in the past two months. However, the tool is free to use and provides a unique approach through its three caching modes and garbage collection customizability. 

#4 – Swift Performance — The Best for More Than One Website

WP Fastest Cache

Best for Multi-Device Use

To cache your site on both your desktop and mobile devices, you want WP Fastest Cache. It’s been downloaded over a million times and has over 50,000 premium users, so you know you’ll be in good company.

WP Fastest Cache has a premium option that is best for users who need a cache plugin for desktop and mobile. The tool is compatible with WPtouch Mobile, a tool that has themes for mobile users of your website. Users have the option to enable and disable caching for mobile and desktop use. 

The plugin supports SSL, CDN, and Cloudflare. With this tool, admins have the option to delete all cached files using the options page. They can also use the options page to delete minified JavaScript and CSS files. The Cache Timeout feature automatically deletes stale files and can be turned off for specific pages. 

WP Fastest Cache has over one million downloads, over 50,000 paid users, and exceptional user review statistics. It has a free version, but its premium plan is far superior. It includes mobile cache, widget cache, image optimizing, database clean up, and Lazy Load.

The premium version of WP Fastest Cache is broken down into three plans that cost a one-time fee. The Bronze plan costs $49.99 and comes with one license.

#6 – Comet Cache — The Best for Membership Sites

Comet Cache

Best for Membership Sites

Membership sites will get a boost from Comet Cache, which automatically caches your members when they’re logged into your site. With an easy two-minute setup and all licenses under $150 one-time, it’s definitely worth a look.

If you run a membership site, Comet Cache is a great option for a cache plugin. This is because it effectively caches logged-in users to your site. Caches are user-specific, and the cache is reset when users submit forms on your site. It can be turned off, but Comet Cache recommends turning it on for membership sites. This feature is not available with the Free version. 

Comet Cache can be set up in just two minutes. It includes GZIP compression, an advanced cache (AC) plugin system, and a debugging mode. The paid versions come with CDN integration for logged-in users, server load monitoring, and an AJAX-powered “clear cache” button.

This plugin has nearly two million downloads, and its Lite Version is free of charge. For more of the advanced features, you must make a one-time purchase of a Pro Version. A single-site license will cost you $39, a three-site license costs $99, and an unlimited-site license costs $139. All Pro Versions come with three years of support. 

If you’re looking for a free WordPress cache plugin, there are better options than Comet Cache Lite. However, its Pro plans have great options for membership sites depending on the number of websites you’re using. 

Methodology for Choosing the Best WordPress Cache Plugin

Before you decide which WordPress cache plugin is right for your website, it’s important to consider three relevant factors. 

Speed

Caching plugins speed up websites to increase performance, improve SEO, and bump up conversions. Search for plugins that advertise things like “increases speed by 300%”. Look for plugins that have been used by top companies. Make sure to choose a tool that has at least 500 positive performance reviews, and few negative ones. 

Third-Party Integrations

Look for a plugin that’s compatible with plugins, hosting, or themes you already use. This will make the implementation process much smoother. 

If you have an eCommerce store that uses WooCommerce, choose a cache plugin that is already compatible with WooCommerce. If you host your site on Bluehost, choose a plugin that integrates with Bluehost. Check to see if the cache plugin integrates with the theme you are using. 

Plugin Tools

WordPress cache plugins come with a variety of different tools, and it’s important to choose one that fits your needs. Helpful tools to keep an eye out for are garbage collection tools for eliminating stale data, image optimizers for downsizing images, and plugin optimizers for enabling and disabling plugins on specific pages.
