Best Practices for Caching on WordPress

In this post, we’re going to talk about how to speed up your WordPress site using caching. We’ll look at what kinds of website content you should cache and what you shouldn’t. This is especially important for sites with online stores or courses, where information changes often and needs to be up-to-date. Let’s dive into how you can make your site faster without messing up the experience for your users.

Understand what to cache

Understanding what to cache on a WordPress site involves distinguishing between static and dynamic content. Static content like images, CSS, and JavaScript files, which do not change frequently, are ideal candidates for caching. This significantly speeds up page load times since the browser can load these files from cache rather than fetching them from the server again. Dynamic content, on the other hand, such as user-specific information in WooCommerce (like cart contents) and progress tracking in LMS plugins, changes regularly and should be excluded from caching to ensure that users always receive the most current information. This nuanced approach helps maintain optimal site performance without compromising user experience.

Exclusions are key

When it comes to caching on WordPress sites with dynamic elements like WooCommerce or LMS plugins, setting exclusions is critical. Specifically, for WooCommerce, it’s important to not cache user-specific pages such as the shopping cart, checkout, and account areas to prevent showing outdated or incorrect information. For LMS platforms, caching exclusions should apply to areas where user progress, like course completion or quiz results, is tracked to ensure accurate, real-time updates for each user.

Some LMS platforms, known for being resource-intensive, demand careful management to ensure that caching enhances site performance without compromising functionality. Properly configuring your caching strategy involves identifying which parts of your site should be excluded from cache to keep dynamic data accurate and up-to-date for each user. This ensures that your website remains fast and responsive, providing a better experience for your visitors while maintaining the integrity of interactive elements.

Choosing the right web server

Choosing the right web server is crucial for optimizing WordPress performance, particularly when it comes to caching. LiteSpeed stands out in this arena with its dedicated LiteSpeed Cache plugin. This tool is specifically designed to enhance WordPress sites by effectively managing cache, including the challenging aspects of dynamic content. LiteSpeed’s technology provides a robust solution for websites that need to selectively cache parts of their content without sacrificing real-time data accuracy or user experience. Its ability to handle dynamic content makes it a superior choice for WordPress sites that demand high performance and reliability.

Helpful LiteSpeed Caching settings


To manage exclusions within LiteSpeed Cache, you’ll find the specific settings under the “Excludes” tab in the LiteSpeed Cache plugin dashboard. This section allows you to list URLs, specify user roles, or identify cookies that should not be cached. It’s a critical step for ensuring dynamic parts of your site, like user-specific pages or live updates, are accurately served.

Image optimization:

For optimizing images, the “Image Optimization” area within the plugin’s dashboard is where you can enable features such as automatic conversion to next-gen formats and implementing lazy loading. These optimizations help in significantly improving your site’s load times without degrading image quality.

Database optimization:

The “Database” tab within the LiteSpeed Cache settings dashboard offers tools for cleaning up your WordPress database. It allows for the removal of unnecessary post revisions, auto drafts, and other elements that can slow down your site. Regular use of these settings helps in keeping your site’s database lean and efficient.

Each of these sections in the LiteSpeed Cache plugin is designed to be user-friendly, allowing you to apply specific optimizations that contribute to the overall performance and speed of your WordPress site.

Wrap up

Caching is a powerful tool for improving WordPress site performance, but it requires careful configuration to work well with dynamic, user-specific content in WooCommerce and LMS plugins. LiteSpeed, combined with its WordPress caching plugin, offers a robust solution for efficiently managing cache while respecting the need for real-time content updates. Remember to regularly review and adjust your caching settings to ensure optimal performance as your site evolves.
