Before we get to the W3 Total Cache features, let us take a look at What actually is caching and how it helps in improving a site’s speed. Should we?

What is Caching?

Now, when a user visits your WordPress website, what happens in the backend is the server your website is hosted on receives a request from the user’s browser. Then, WordPress processes the request and generates static files to fulfill the request and build the webpage in the user’s browser. Now, depending upon certain factors like the theme, plugins you are using, type of content you have. The requests might be a lot which makes the webpage speed slower.

Caching does a great job in this regard by grabbing the static webpage files and storing them on the web server, sending a copy to a content delivery network (CDN), and even storing a copy on the website visitor’s browser. This way, when the visitor accesses the webpage again, the static webpage files are loaded directly from the web server which results in faster loading of the page since the web server didn’t have to process the files again.

Now, let us take a look at How to Install W3 Total Cache on your WordPress Website.

How to Install W3 Total Cache?

In order to install the W3 Total Cache on your WordPress Website, you need to follow these steps carefully:

  • First of all, you need to login to your WordPress Dashboard.
  • Now, go to Plugins >> Add New from the sidebar.
  • Here, search for W3 Total Cache.
  • Install the one by Frederick Townes having over 1 million Installs.
  • Now, click on Activate button to activate the Plugin.

That’s it! You have successfully installed W3 Total Cache on your WordPress Website. Now, it’s time to get to the real job and speed up your slow WordPress site using the W3 Total Cache.

How to speed up your WordPress Website using W3 Total Cache

Now, there are some settings which do work for most of the people out there and would make your WordPress website faster. Makes some sense? Great! So let us now take a look at options that the W3 Total Cache has to offer and what it does. This way, you’ll get a better understanding of what would work for you. We would also be sharing some settings with you guys.

The very first thing you should do after installing the plugin is to just click on the Compatibility check button to check whether or not the W3 Total Cache is even compatible with your server or not. There is something that the W3 Total Cache requires in order to work properly. For instance, you need a minimum WordPress version 2.8 with PHP 5.3.

Now, let us take a look at the W3 Total Cache options and what they are about. Should we?

General Settings

General

Here, you will find an option for Preview which will create a separate container for site settings and would not save the settings straight off. You can play around with the settings in the Preview Mode and over the top, you would be able to see three different options:

The first one is for Disable which pushes the changes made and disable the preview mode.

The second option is for Deploy which pushes the changes made.

And the third option for Preview which opens your site with the preview settings so that you can take a look at What your site would be like if you save the changes made under preview mode.

Page Cache

The next sub-menu under the General Settings menu is Page Cache. It is indeed the most important option of the W3 Total Cache. You should definitely enable this option to enable caching. Now, there are some methods to cache static copies of your site’s pages and posts:

Disk: Enhanced: If you using a Shared Hosting, then you should go with this method.

Disk: Basic: Shared Server Users should go with this option.

If you are using Dedicated or virtual private server, you can select one of Opcode Caching method.

Opcode: WinCache: If you are using a Windows Machine as a Server, then you should opt for this option.

Memcache: If you are hosting your website on a multi-server, then you should go with this caching option.

Minify

What is Minification? Let’s say your WordPress theme is using a CSS file that has unwanted tabs and white spaces and the size of the file is 150KB. Now, What minification does, removes all the white space in order to decrease the size of the CSS/JS file. For instance, A file with size 150KB would become a file with size 100KB after minification.

The other benefit of minification is you don’t have to worry about bad people reading your CSS/JS files because they can’t really understand anything as there are no white spaces, all they would see is some random code dumped on the screen.

Now, we would not be going in too much deep about the Minify as it would make this post a lot longer. For beginners, we can say that this option will combine and minimize the size of the HTML, CSS, and JS files of your website. Please do note that this enabling this might result in the visually broken site, so go ahead with precaution.

Database Cache

Now, if you are hosting your WordPress Website on a shared server, then you should leave this option disabled. This is simply because this utilizes more resources and most of the times, a shared server is not powerful enough to use database caching.

For those of our users who have a VPS or a Dedicated Server and are making things easier with the Server Avatar, you can go ahead and try enabling this option. Once you enable this option, take a look at the site’s speed and if it becomes slower afterward, then disable the Database Caching.

Object Cache

Object Cache is something which is built into the WordPress Core. This caches objects from Object Cache API to minimize the number of complex database queries. It is quite easy to set up. Now, some of you might get benefits from this option while others not so much. How. you ask? Well, for instance, if you have BuddyPress sites, bbPress sites, and so forth. This option would really help you.

On the other hand, if you have a blog or business website from a shared server, then in most of the cases, this option won’t help you at all.

Browser Cache

Now, this is one of the most important features of the W3 Total Cache. Enabling this option is quite simple and is not a difficult job at all. All you gotta do is simply click on the checkbox to turn it on. When this option is enabled, the website resources will be cached by website visitor browsers. That way, when a visitor comes back to your website, it would be a lot faster than before since some of the resources were loaded locally from the browser’s cache.

CDN

This is a pretty forward option. If you are using any Content Delivery Network or the CDN, then you should enable and set this option up. Setting up a CDN for your blog is not a difficult job at all. Once you enable this option, a new menu named CDN will be added. In this menu, you can configure caching and CDN at the same time for your WordPress website which might improve your site’s speed a lot.

Reverse Proxy

If you are someone who has installed Varnish on your server. If you are someone who does not have any idea about what is varnish, then you should definitely leave this option. You would need to have the root access for your server and will have to go through some advanced server configuration steps to make this option work.

Miscellaneous

Here, you can enable a Google PageSpeed widget in the W3TC dashboard. All you need to do is just enter the PageSpeed API and you are good to go. Other options include Verify rewrite rules, Enable file locking, Optimize disk enhanced page and minify disk caching for NFS, and Enable Edge Mode.

Import/Export Settings

As the name suggests, you can Import/Export Settings using this option. Let’s say you wanna use the same set of settings on some other WordPress Website. All you need to do is simply export the settings and download the settings file. Then, go to other site and import file to use the same set of settings. Also, if you think you have messed up with the settings and wanna rollback to default settings then, you can simply press Restore Default Settings button.

Page cache

General

Configure the General settings according to the settings below. Do note that you should enable SSL option only if you have an SSL installed on your website.

Cache Preload

Now, as the name suggests, this option generates a cache file automatically even before a visitor requests the page. This will drastically increase the speed of your WordPress Website.

Purge Policy

This option lets you select pages are to be purged whenever a new post is published or updated.

Advanced

Here, you can dig a bit deeper and can exclude some browsers from receiving cached versions, enable the Compatibility mode, create exceptions and more. We won’t really recommend you play with other options rather than enabling the Compatibility mode.

Minify

General

Here, you can Rewrite URL Structure which is also known as “Fancy Links”. Also, you can also enable minify error notifications which would help you in taking a look at errors due to minifying, so you can fix them.

HTML & XML

Now, this would minify (minimize requests) the HTML & XML files of your WordPress website. This option really helps in improving the page speed score and overall page speed of your WordPress Website.

JS And CSS

This option would minify (minimize requests) the JS & CSS files of your WordPress website. This option also helps in improving the page speed score and overall page speed of your WordPress Website.

Advanced

Here, you can set the update interval and when to delete expired cache data. Also, you can exclude specific pages and files from minification.

Browser cache
