How to Set Up a WordPress Caching Plugin

A caching plugin creates static HTML copies of your pages so WordPress doesn't need to execute PHP and database queries for every visitor. This can reduce page load times by 50-90%.

Option 1: LiteSpeed Cache (Free, Best for LiteSpeed Servers)

1. Install LiteSpeed Cache from the plugin directory.


2. Go to LiteSpeed Cache → Cache.


3. Enable "Cache" toggle.


4. Under "Cache Logged-in Users," leave disabled unless needed.


5. Enable CSS/JS minification under Page Optimization.

Option 2: WP Super Cache (Free, Simple)

1. Install WP Super Cache.


2. Go to Settings → WP Super Cache.


3. Select "Caching On" and click "Update Status".


4. Under Advanced, enable "Use mod_rewrite" for best performance.

Option 3: WP Rocket (Premium, Best UX)

1. Purchase and install WP Rocket.


2. It works immediately with good defaults — page caching, browser caching, and GZIP compression are enabled automatically.


3. Enable "Optimize CSS Delivery" and "Delay JavaScript Execution" for additional speed gains.

After Installation

• Clear the cache after making changes to your site


• Test logged-in vs. logged-out views to ensure caching works correctly


• Check that dynamic features (forms, shopping carts) still work

Verify with InspectWP

After setting up caching, run a new InspectWP scan. The WordPress section should detect the cache plugin as active.
