If you use WordPress as your publishing platform and are concerned about speeding up your website, caching will help you. The faster a web page loads, the better the user experience is. This is how WordPress caching works: it generates a copy of your web pages and stores them in your server as static files (i.e. as HTML documents) and/or cached database queries. Afterwards, when a site visitor arrives at a particular page, the server gives them the cached page rather than re-querying your database and dynamically generating it, thus speeding up page response times and potentially reducing the server resources required for generating and serving a web page. For WordPress users, the easiest and quickest way to implement a caching system is by the use of a WordPress plugin. There are several WordPress cache plugins out there, and below, you’ll find the most popular, highly recommended ones.
