Best WordPress Caching Plugins to Speed Up Your Website

Everyone wants to load his or her website in the shortest possible time. A fast website can rank higher in search engine results and get more page visits from searches, social sites, and other referral channels. If your site takes a long time to load, it will seriously affect your traffic and income. 

Caching helps you to serve content faster and enhance the overall website performance. Many web hosts provides a built-in caching system to speed up your WordPress. But some times, it may not be enough. In such a situation, you may need to install a third-party caching plugin on your site to reduce page loading time. 

Today, we pick 7 best WordPress caching plugins that can boost your page speed significantly. 

What's Caching?

Every webpage is a combination of HTML, JavaScript, CSS files and scripts. Your theme and plugins will add some coding scripts to the front-end for smooth functioning. All such things should be properly loaded to open your site as expected. 

When a visitor enters a URL, a request sends from the browser to the server to deliver relevant resources, then the hosting server process the call, and sends files back to the user browser. Since this kind of two-way communication is involved, your page loading time will increase based on the number of files needed to render a web page completely. 

Caching is a process of your frequently accessed resources in a temporary storage so they can be served quickly to the users. It will help browsers to skip communicating with the servers and load pages faster. 

By default, a WordPress content is generated dynamically. ie it loads all elements in a page including images, files, and scripts. When someone visits your page for the first time, the caching plugin saves its static version in the cache folder to makes it available to users quickly for subsequent visits. This is what WordPress caching plugins do on your website. Thus they will help you to reduce page loading time and speed up WordPress.
