If you want to reduce your server load and improve your website performance, a good caching plugin can help. But there’s multiple caching plugins that you can choose from, so which is right for your business?
We’re going to take a look through some of the best options available right now so you can pick the right WordPress plugin for your website.
How Page Caching Works
First, let’s cover what page caching is. When you visit a website, your browser sends a request to a web server, which then processes that request, builds the page, and sends it back to your browser. This is fine, but if you have a website with a lot of visitors, it can use up your server resources, as well as take time to load.
This is where WordPress caching plugins can be extremely useful. Page caching works by saving a static copy of the fully-rendered page, which means that you don’t need to load it in full every time that someone visits your site, as you can serve the same cached file again to the next visitor.
This can dramatically improve load times (often by 2-5x) and reduces server load, which in turn means a better user experience for your visitors (and potentially improved SEO rankings as a knock on effect of that).
If you’re not using a page caching plugin on your website, you’re missing out on the opportunity to speed up your site, but it’s important to exclude certain pages – especially for e-commerce websites. Let’s look at the best WordPress caching plugins that are currently available.
WP Rocket – Highly recommended
There’s a reason why WP Rocket is now the third most used WordPress plugin. It’s the best premium caching option for WordPress users in general, but it’s especially recommended for WooCommerce store owners.
Why? Well, it comes with built-in WooCommerce compatibility, which means you don’t need to worry about it breaking your website. The plugin’s page caching dramatically improves loading speeds, while its GZIP compression and file minification also help to further reduce load times by shrinking CSS and static HTML files.
For WooCommerce stores specifically, many of them with image-heavy product catalogs. This is where the lazy loading feature is particularly valuable, deferring off-screen images until customers scroll to them.
When you add this to WP Rocket’s database optimization, which cleans up WooCommerce’s notoriously bloated tables by removing redundant order data, transients, and revisions.
WP Rocket definitely stands out as one of the most powerful and beginner-friendly WooCommerce caching plugins, and it receives lots of love from the WooCommerce community due to its intuitive UI and quick setup.
But if you do opt for WP Rocket, make sure that you exclude your Account and Cart pages and avoid Javascript file minification too, as per WooCommerce’s recommendations.
W3 Total Cache
The only downside to WP Rocket is the expense, which can add up if you need several licences to cover multiple websites. In contrast to this, W3 Total Cache is a free, open-source plugin that’s surprisingly powerful, but it does require more careful configuration to avoid breaking your online shop.
As with other caching plugins, you’ll need to manually add cart, checkout, my-account, and other critical pages to the exclusion list—if you don’t do this properly, your customers could end up seeing cached versions of personal pages or experiencing checkout errors.
The database caching that W3TC offers significantly reduces query execution time, which is particularly beneficial for WooCommerce stores with extensive product catalogs. The minification options for CSS and JavaScript can shrink file sizes, though they occasionally conflict with WooCommerce themes (worth testing, many plugins recommend disabling JavaScript minification).
Fragment caching allows static parts of pages to remain cached while dynamic elements (like cart totals) stay current. This means that when your users browse your e-commerce store, your server will check if these elements or sections are cached, and then serve the cached version instead of generating them from scratch.
The real selling point of W3TC is that it’s a completely free plugin, and while other premium plugins may be more intuitive, it does have most of the caching functionality needed for a WooCommerce store. If you have some time to invest, it may prove to be a good choice as a solid caching plugin.
WP Super Cache
Another great option for WordPress users is WP Super Cache. Like W3 Total Cache, it’s a free open-source plugin, which means all features are included with the free version, and there’s no upgrade needed after installation.
WP Super Cache is perhaps the oldest & most popular free caching plugin available, originally run by Donncha Ó Caoimh (an Automattic employee) it was taken under the wing of Jetpack in 2022, who are now the plugin’s support team. Jetpack, which is one of the best backup and security plugins, is also owned by Automattic, as is WooCommerce, which was acquired in 2015 (Automattic is the parent organization of WordPress.com).
Why mention all of this? Well, this close relationship means that WP Super Cache works natively with WooCommerce. So, even though it has a simpler layout, it still does the job well, and integrates especially well with WooCommerce.
While WP Super Cache lacks some advanced features found in premium options, it covers the essentials quite well; browser caching, GZIP compression, and page caching work to deliver a faster website. The preload function can cache your product catalog in advance, which ensures fast loading even for first-time visitors, while the CDN support helps deliver product images quickly regardless of where your customers are located.
For small WooCommerce shops looking for a free, reliable caching plugin for their WordPress website that can minify CSS, JS files and much more, the WP Super Cache plugin is a great option.
