A Full Page Cache Magento 2 allows you to manage the priority of cached content with great efficiency.
There are a few types of priorities available in our solution:
Page popularity (number of visits)
Page type (category, product, CMS page, layered navigation, etc.)
Product type
Customer Group
Cache Prioritization allows you to put the right stress on the most high-demand pages. For example, one of the most visited store pages might be your Sale/Promotion page. As such, you can set a higher priority for it and provide your customers with the best loading speed for this content!
