Caching is a popularly recommended technique for optimizing WordPress website performance. It increases website traffic and conversion rates by speeding up the website and page load times. But… How does caching work?
Caching is a mechanism for storing requested information (static files for websites) in a temporary storage location (a cache) for faster access. Here’s how it works practically:
Visitor A requests the homepage of your website, the hosting server builds the code, returns the result to the visitor’s browser, and stores the result (a cached version) on the server. Visitor B requests the home page, but the server doesn’t build the code again. Instead, it serves the previously cached page.
Without caching, the server has to build the code every time a visitor requests a page. This process is at the expense of the computer’s resources (CPU, RAM, disk etc.) and, of course, the time taken to complete the task execution. Caching saves time and the resources required to complete processing.
WordPress is a dynamic content management system (CMS). When a visitor requests a page, the hosting fetches data from the database and runs a collection of PHP scripts to process the data before sending a response (in the form of a web page) to the visitor’s browsers. This process increases the load on the hosting server as a website’s traffic increases. Hence, the need for caching on WordPress websites.
There are several WordPress caching plugins on WordPress.org, but not all can serve your website’s needs. This article will discuss the best WordPress caching plugin for your website and why you should understand your caching needs.
All plugins perform best in different use cases, so there is no best per se.
What are Caching Plugins on WordPress, and Why do You Need One?
WordPress caching plugins handle page caching for WordPress websites. Technically, a cache plugin creates a static version of a web page that it delivers to a visitor on subsequent requests. WordPress cache plugins operate in slightly different ways. Some cache plugins allow you to select the pages you don’t want cached. An example of where this is useful is in WordPress-managed e-commerce storefronts. The cart and checkout pages shouldn’t be cached for the best user experience.
However, do you need a caching plugin for your WordPress? It’s important to understand the types of caching – browser and server. Browser-level caching is handled by a visitor’s browser and is unique to a visitor’s device. Server-level caching is handled by the hosting server. It implements caching for all website visitors.
If you’re using a automated WordPress hosting platform like 10Web, you don’t have to worry about server-level caching. 10Web uses backend or server caching for websites hosted on 10Web to cache everything from pages to feeds to 301-redirects on subdomains for the websites hosted on the platform. It also makes use of Nginx FastCGI Caching, the quickest page cache solution, which gives you control over which pages are cached and guarantees that pages are fetched as quickly as possible.

If you search with the keyword “cache” in the WordPress plugin repository, you should see these WP Total Cache and WP Super Cache next to each other with impressive reviews and download counts. This cache plugin developed by the creators of WordPress, Automattic, has limited features. It generates static HTML files from your website and serves those files to your users instead of hitting the server every time. It is simple to use and provides recommended settings for less technical users.
