How to Setup W3 Total Cache to Optimize WordPress Websites

We are going to use w3 total cache to Optimize WordPress websites. By default WordPress is a dynamic CMS (Content Management System). This means that for every visitor request that WordPress has to process, it must first connect to the database to see if the requested page even exists.

It’s free and very effective. The W3 Total Cache plugin has been around for years and is successfully used by millions of websites. However, it can be a little tricky to setup when you start using it, that’s why we propose this simple guide for the Customize theme.

Using W3 Total Cache plugin enables the process of storing data from existing requests to be re-used for subsequent requests.  Caching prevents repeating database request and serving of same information, by storing data that has already been asked for and serves it up instantly.

W3 Total cache will also help you reduce the sizes of your page by  compressing it (HTML, CSS, JavaScript) before it’s actually renders by your browser.
