A Full Magento 2 Cache Warmer can create a cache version of any newly-saved page. For example, you can create a new product (category, or any other store page) or edit existing ones. Next, visit this page as a customer so that the page will appear indexed by our module. Alternatively, you can wait for a crawler to find the page, or it will be added during the synchronization of the Full Page Cache Warmer sources on Cron task.
You can create pages/categories/products in your store, and the Full Page Cache Warmer will do the rest for you after a while. You can also visit the new page to speed up its caching.
