How to Configure W3 Total Cache

Share This Article [TheChamp-Sharing]

So you’ve set up your WordPress website, but it’s slow and you keep hearing about optimization. One of the most widely used and popular tools to help you with optimizing your site is from a third party plugin called W3 Total Cache. There are other caching tools available, but none that do as much when properly configured. There are a lot of options, but the setup is really much simpler than it seems. As always, we highly recommend you have a backup of your account before making changes to your WordPress configuration and installing any plugins. 


Install and Activate


First things first, you need to go to your Plugins section and click Add New. From there, type W3 into the search bar and W3 Total Cache should be the first option given:


W3 Total Cache Installation


Once installed and activated, you’ll have a new section in your sidebar, the Performance tab:

From here, you want to click on the General Settings tab first, and you’ll only need to enable the following setting:


W3 Total Cache set page cache


Scroll down further and the Browser Cache setting should already be checked:


W3 Browser Cache Setting


Now just click Save All Settings and click on the Page Cache settings next. We will now note the sections in which you need to make changes, starting with the first section General:

Then to the Cache Preload section:

Lastly, locate the Advanced section and enable Compatibility Mode(recommended by the creator of the plugin):

Once again, click Save All Settings, and then move on to the Browser Cache section and setup as follows:

Now just click to Save all settings, and you will have completed the basic W3 Total Cache installation and should be seeing much higher page grading at GTMetrix and other testing sites, as well as much improved speeds. There are other configurations possible if using an outside CDN service, but for general usage the settings detailed here will be all that you need.
