How caching works

Caching helps websites load faster by storing generated content so the server does not have to rebuild every page from scratch on every visit.

Without caching

WordPress often has to run PHP code, query the database, load plugins, build the page and send it to the visitor every time.

With caching

A cached version of the page can be served much faster because the heavy work has already been done.

Types of caching

Page cache: stores full page output.

Browser cache: tells visitors’ browsers to reuse static files.

Object cache: can reduce repeated database work on some setups.

CDN cache: serves files from locations closer to visitors.

When cache should be cleared

After major design changes.

After updating important content.

After changing menus or global templates.

When troubleshooting stale content.

When cache should not be cleared

Do not clear cache repeatedly for no reason. A warm cache helps your website stay fast.

Important notes

Logged-in WordPress admin areas should not be cached like normal public pages.
