WordPress Cache Preloading Explained

Preloading prepares cached content before the next real visitor requests it.

The cold-cache problem

After a cache is cleared, the first request may need to regenerate a page. Preloading reduces reliance on a visitor being the one who triggers that work.

How it helps

A preloader can discover important URLs and generate cache entries in advance, helping popular pages stay ready to serve.

Resource trade-offs

Preloading creates requests and consumes server resources. Very large sites need sensible crawl and regeneration behavior.

Where WP Rocket fits

WP Rocket includes cache-preloading functionality as part of its broader performance workflow. That can be useful when you prefer one plugin to coordinate caching and related optimizations.
