Caching stores ready-made copies of your pages so they load faster.

1. WordPress: install a caching plugin (for example, WP Super Cache, W3 Total Cache, or LiteSpeed Cache if your server supports it), then enable page caching in its settings.
2. Server-level caching: if your hosting includes LiteSpeed, the LiteSpeed Cache plugin gives the best results.
3. Browser caching: add cache-control rules via .htaccess, or let your caching plugin handle it.

Tip: After enabling caching, clear it (article 100) whenever you make changes, or visitors may see the old version.
