You can choose Action Based cache expiry, the traditional Time Based cache expiry, or Intelligent cache expiry option.

Action- and Time Based are the best choices for most sites and webshops. WooCommerce, BBPress and Buddypress support is included. If you don’t use any expirable on frontend (like CRSF nonce, etc) you should choose the Action Based expiry. It will clear the cache only if something was modified, or if it was triggered manually.

Choose intelligent mode only if some of your pages are modified frequently from 3rd party source (eg: live scores, currency rates, etc)
