How to Set Up Caching in WordPress (LiteSpeed Cache / W3 Total Cache / WP Super Cache)

Caching stores a static version of your pages so WordPress doesn't have to rebuild them from scratch on every visit. It's one of the single biggest performance improvements you can make to a WordPress site.

Recommended: LiteSpeed Cache

Because dotCanada uses LiteSpeed Web Server, the LiteSpeed Cache plugin is the most effective option - it communicates directly with the server's built-in caching engine for the best possible results.

1. Go to Plugins > Add New and search for LiteSpeed Cache.
2. Install and activate the plugin.
3. Go to LiteSpeed Cache > Cache in your dashboard and enable caching.
4. Explore the Page Optimization tab to enable minification and other performance features.

Alternative: W3 Total Cache

W3 Total Cache is a full-featured caching plugin compatible with most hosting environments. After installing and activating it:

• Enable Page Cache under General Settings
• Enable Browser Cache for static asset caching
• Optionally enable Minify for CSS and JS compression

Alternative: WP Super Cache

WP Super Cache is a simpler option developed by Automattic. After activating it, go to Settings > WP Super Cache and turn caching on. It works well for lower-traffic sites that need a straightforward setup.

Tips for All Caching Plugins

• Always clear your cache after making theme or plugin changes
• Exclude admin pages and checkout pages (WooCommerce) from caching
• Test your site speed before and after to confirm the improvement
