You don't really have to be a web designer to know that a site doesn't only have to look good. The usability part is extremely important and should not be neglected as well. When it comes to usability and performance, you should try to optimize everything – caching is one thing you should consider.

Page load time is one important aspect for performance optimization, which means that you need to keep an eye on how fast your page loads, no matter how simple or complex your site is or what kind of CMS you are using. In this article we will explain what caching can do for you and why it is good to use WordPress caching plugins to improve the performance of your website.

What Does Caching Mean?

Caching is the process of storing elements of your website in the cache of the browser or static HTML files on the server to ensure easier and faster access when it comes to future visits. When a visitor navigates on your website, the PHP code will process the request, call the database for every query that's needed and then puts out an HTML file which will be displayed by your browser.

Enabling caching means that only the first visitor to a certain page will have to wait until he gets the final HTML page. The next visitors will be served directly the static HTML file that was loaded before, without going through a lengthy process again with separate database and file requests.

Caching can provide a better user experience, faster page load, less database requests and reduced network traffic. Not only large, extensive and popular websites with many users benefit from caching, but also small websites will. Next you will find some great WordPress caching plugins:

WP Super Cache (Free)

The WP Super Cache plugin generates static HTML files from your dynamic WordPress website or blog. After a HTML file is generated, your webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.

W3 Total Cache (Free & Premium)

The W3 Total Cache WordPress plugin enhances your server performance and thus gives your users a great experience surfing on your website. This plugin caches every aspect of your site, minimizes the download times and offers transparent content delivery network (CDN) integration.
