How it works

Up and running in under 5 minutes.

01

Install & activate

Install the plugin from WordPress.org and activate it. No configuration is required to get started.

02

Enter your sitemap URL

Paste in your sitemap index URL (e.g. /sitemap_index.xml). The plugin will parse it and discover all your pages automatically.

03

Enable scheduling

Toggle on scheduled crawling and set your interval — every 6 hours is a good default. Enable the LiteSpeed variants you use (WebP, Mobile, Guest Mode).

04

Sit back and relax

The plugin runs silently in the background via WordPress cron. Check the live log tail in the admin any time to see exactly what was warmed.

Frequently asked questions

Does it work with caching plugins other than LiteSpeed?

Yes — it works with any caching layer by simply making HTTP requests to your URLs. The LiteSpeed-specific variant headers (WebP, Mobile, Guest Mode) are optional. If you use a different cache plugin, just leave those variants disabled.

Will it slow down my server?

No. The plugin runs during off-peak cron windows and includes configurable delays between requests (default 1500ms). It also respects your server load by pausing automatically when the LiteSpeed crawler is active.

What if I have thousands of URLs?

You can set a "Max URLs per run" limit. The plugin uses a cursor — each run picks up where the last one left off, so over multiple runs every page gets warmed without hammering your server in one go.

Is WooCommerce supported?

Yes. You can exclude cart, checkout, and account URLs using the "Skip if URL contains" setting, so only cacheable public pages are warmed.
