SmartCache stores ready-made copies of your pages on the server, so repeat visitors get a fast response without WordPress rebuilding the page each time.
Turn on SmartCache
Open your site, then under Hosting select Smart Cache. Tick Enable SmartCache and click Save.
When to use it
SmartCache suits most sites and is safe to leave on. If you run a store or membership site with content that changes per visitor, test that those dynamic pages still behave correctly.
Clearing the cache
If a change does not show up straight away, use the Clear Cache button at the top of any site page to flush the cached pages.
