Here is the step by step manual for setting up W3 Total Cache plugin on your WordPress blog. Access the Plugins section and click on the Settings link available with this plugin.

W3 Total Cache General Settings

First of all lets go through the General settings section of W3 Total Cache plugin.

General

You should keep preview mode as disable.

Page Cache

Page Cache: Enable
Page Cache Method: Disk Enhanced

Page Cache method can be basic or enhanced for shared hosting. Enhanced method performs much better than the basic mode. Enhanced mode use the .htaccess file while basic mode does not use that. If you are getting errors while using the Disk enhanced caching method, you should switch to basic mode.

Minify

Minify: Enable
Minify Mode: Auto
Minify Cache Method: Disk
HTML minifier: Default
JS minifier: JSMin (default)
CSS minifier: CSS Tidy (if face problems use Default)

You should use other options from Minify Cache method if you are on a virtual host or dedicated host. These settings will work for shared hosting WordPress blogs only.

Database Cache

Database Cache: Enable
Database Cache Method: Disk

Again you should opt for other options if your website is hosted on virtual or dedicated server.

Object Cache

Object Cache: Enable
Object Cache Method: Disk

You will be using other options if your website is not hosted on shared hosting.

Browser Cache

Browser Cache: Enable

CDN

You should enable CDN if you have decided to purchase a CDN. For running a normal blog, you would not need a CDN. You should go for it if your website is getting millions of visitors every month from different traffic sources.

Your WordPress website can run smoothly with a W3 Total Cache type of strong caching plugin even if you are on a shared hosting and your website is getting 10000-15000 visits per day.

Varnish

Enable varnish cache purging

You can know in detail about Varnish Cache from Wikipedia page here.

I’m leaving out the Miscellaneous and Debug options as such.

Import/Export Settings

If you want to install W3 Total Cache plugin on multiple WordPress websites that you own, then this feature will be really handy for you. Once you are finished with setting W3 Total Cache plugin for one blog, you can replicate the same settings on other WordPress blogs by downloading the W3 Total Cache plugin settings from this section. All you have to do is import this W3 Total Cache configuration on other blogs where you want to install this plugin.
