How To Install & Configure W3 Total Cache WordPress Plugin

Page speed is important for a better user experience and also for SEO. In WordPress, there are many cache plugins available.

But out of all of them, WP Super Cache and W3 Total Cache (W3TC) are my favorite. The major difference between these two plugin is: Super cache is easy to configure where as W3TC has too many options & you need to configure extensively.

I have heard a lot of good things about the W3 Total Cache plugin.

It’s a lot like WP Super Cache, but with more options. In particular, if you are planning on using a CDN, the W3 Total Cache plugin is really great.

To speed up loading time, I’m using MaxCDN on my blog network. To supplement this, I also tested out the W3 Total Cache plugin.

This test was performed on my WordPress hosting blog

How To Install W3 Total Cache

Search for “W3 Total Cache” from the “Add new plugin” section in the WordPress dashboard. Or you can download the plugin from here and manually upload it to your server.

Note: Make sure to uninstall the WP Super Cache plugin or any other WordPress cache plugin.

How To Configure W3 Total Cache

The setup options in W3 Total Cache are much more advanced than those in WP Super Cache. But don’t get confused! I’ll show you how I’ve set it up on my blog, and you can review and copy the settings for your own site.


Once you have installed and activated W3 Total Cache, go to Performance > General and enable everything you want to cache. Later on, you can make changes to individual settings and fine tune your W3TC configuration.

When you are done, click on “Save all settings”.

After making changes, click on “Preview” to check if everything is OK. If everything looks good, click on “Deploy” to make these settings live.

By default, all of the essential settings are checked. Review them, and move on to the next setting.


All of the settings in “Minify” are also plug and play.

But if you are not using a CDN, you might want to disable “Automatically upload modified files”.

One cool thing about W3 Total Cache is the support for extensions.

It offers extensions for a few popular WordPress plugins & themes such as Yoast SEO, Genesis, CloudFlare & Feedburner.

How To Integrate Google Page Speed with W3 Total Cache

Earlier I wrote about how to configure W3 Total Cache and also a little about Google Page Speed.

The latest version of W3 Total Cache allows you to integrate with Google Page Speed to see the performance of your site. The faster your site is, the better it is for search engine ranking.

In this guide, I will be sharing how to enable Google Page Speed inside of W3 Total Cache.

Once you have installed W3 Total Cache, go to the plugin settings and click on the tab “Miscellaneous”.

Click on “Enable Google Page Speed dashboard widget”.

You need to enter a Page Speed API to enable this feature.

How to get a Google Page Speed API?

Go to the Google API homepage and login with your Google ID. Look for the option “Page Speed Online API” and switch it ON.

Now click on the “API Access” tab on the left sidebar and you will see your API key.
