How to Clear Cache in WordPress - Step-by-Step Guide for Beginners

How Does Cache Work?

When you visit a website, your web browser requests the server to load various elements of the requested site including CSS, image files, HTML, JavaScript files, etc. the more elements a web page has, the more time it will take to respond.

The speed of your site plays a vital role when it comes to performance. It offers a great user experience by increasing the page loading speeds and reducing the page response time. Caching is a process of optimizing the speed of your WordPress site. Whenever you visit a site, your browser stores the static files of that website, including images, stylesheets, HTML, and JavaScript files. With this, when you visit the website next time, it will load faster, ultimately increasing the performance, speed, and user experience. In simpler words, your browser would create fewer requests (for dynamic content only) to the server and fetch the cached static files faster.

Types of Caches in WordPress

Caching is a crucial mechanism for enhancing your WordPress website’s performance. By storing static copies of your site’s content, cache reduces the need to repeatedly fetch data from the server, thereby speeding up load times. However, understanding the types of caches used in WordPress is key to managing them effectively. Here are the most common types of caches:

Browser Cache

Browser cache stores static resources, such as images, JavaScript, and CSS files, on the user’s local device. This allows returning visitors to load pages faster since their browser doesn’t need to re-download these elements each time. While browser cache improves user experience, it can sometimes display outdated content if changes are made to your site. Clearing browser cache ensures visitors see the latest updates.

Server Cache

Server-side caching refers to caching mechanisms implemented at the hosting level. This includes methods like object caching, opcode caching, or full-page caching. Hosting providers such as SiteGround and Bluehost often offer built-in server caching tools. By caching pages directly on the server, this type of cache significantly reduces the load on your website’s database, improving overall site speed.

WordPress Caching Plugins

WordPress caching plugins, like WP Rocket or W3 Total Cache, create static versions of your site’s dynamic pages. These plugins store cached pages and serve them to visitors, bypassing the need for repeated PHP processing. This is one of the easiest and most popular ways to implement caching in WordPress. However, if the cached content isn’t cleared after updates, users may encounter outdated information.

CDN Cache

A Content Delivery Network (CDN) cache stores copies of your website’s content across multiple servers worldwide. This reduces latency by delivering cached content from a server closest to the user’s location. Popular CDN providers like Cloudflare, KeyCDN, and StackPath offer caching options that improve global website performance. Clearing CDN cache is often necessary when updating files, ensuring visitors receive the most current version of your site.

Why Do We Need to Clear Cache?

No doubt, caching sounds like a good thing. Considering it decreases the response time and helps websites load faster, ultimately offering a better site performance. So what possibly can be the reason to clear cache? Basically, when you make edits to your site, you sure will want your audience to see the changes you made. However, if your audience is still seeing the cached files, they will see the outdated version of your site. As a result, your audience will not be able to benefit from the latest edits. Moreover, when WordPress launches an updated version or plugins launches an updated version for better performance or improved security. In this scenario, you will have to clear cache from WordPress to make the web browsers fetch and cache the latest version of your site and other changes you made.

Will clearing the cache affect my website’s visitors?

No, clearing the cache won’t affect your visitors negatively. Instead, it ensures they see the most up-to-date version of your website. However, if caching is disabled for a long time, it may temporarily slow down load times for users until the cache is rebuilt.
