W3 Total Cache help to reduce page loading times and improve the overall user experience.


The W3 Total Cache plugin boasts a number of features including caching, minifying and content delivery network integration. It is compatible with shared hosting, virtual private / dedicated servers and dedicated servers / clusters. It provides transparent content delivery network management with both theme files and WordPress itself. It also offers mobile support. See below for a closer look at the three main features.

1. Caching

Usually when you visit a website, the page is generated in that very moment. It does this by connecting to a database to access the content. The server then puts the content in a page and presents it to the user. If you only have a small number of visitors using your site at one time, then this practice is fine, however websites that have hundreds of visitors attempting to load pages at the same time, will cause your server to slow down dramatically. A cache plugin like W3 makes a copy of the pages and stores them on users’ browsers to serve to them next time they visit.

Instead of having to deliver the content to individual users, W3 Total Cache stores a website’s images, style sheets, plugin content and JavaScript in an optimised way on a content delivery network. This information is then delivered to the user’s browser with the instructions that the browser must hold onto it.

Caching is the recommended way of improving your website’s performance. From using the plugin you will see significant improvements in page loading times.

2. Content delivery network support

W3 Total Cache can be integrated with a number of content delivery networks including Amazon S3, Amazon CloudFront and any other CDN that is compatible with FTP uploads. The CDN must be set up by the website owner separately. Content delivery networks are optimised clusters of servers that are spread out across the planet, close to users trying to access them. Most of the elements your site needs to deliver to the user can be stored on a content delivery network.

Content delivery networks require set-up, but they work automatically and do not need maintaining. They also provide inexpensive hosting, enabling users to save on their server costs. All of the files that need storing are saved and delivered in an optimised way, increasing the efficiency of the site and improving the overall user experience.

3. Minifying

The Total Cache plugin also uses minifying to improve site performance. It does this by taking a variety of style sheets and coding that are spread across multiple pages and locations (even third party sites) and brings them all together in one simply bundle. By doing this, it reduces the number of back and forth trips users’ browsers have to make in order to load a website.


Installing the W3 Total Cache plugin will greatly improve your YSlow score. For those who do not know, YSlow is a testing tool that evaluates the performance of websites. By using the plugin, many website owners will find that their site is able to achieve a Grade A, as it will meet most of the optimisation criteria.

Using W3 will also lead to increased conversion rates and better site performance, both of which will help your website ranking in search engines like Google. The improvement in page loading time should also have a positive effect on your websites Google Page Speed score. The quicker pages load, the longer visitors will stay on your site, giving them the chance to view more pages.

The Total Cache plugin also improves overall web server performance so that shared servers are able to cope with high traffic periods. Users of this plugin have the opportunity to save up to eighty per cent of their bandwidth by minifying and compressing HTML, CSS, JavaScript and various other feeds.
