Install & configure W3 Total Cache settings
W3 Total Cache Install
To increase our WordPress site speed, we will absolutely want to install W3 Total Cache. W3 Total Cache is by far most comprehensive and effective plug-in you can install to increase your site speed. It's a little tricky to configure the first time around, so we will handle one step at a time.
W3 Total Cache Browser Cache
We now want to configure the browser cache settings. The browser cache tells browsers, like Chrome and Firefox, not to download content and files that they've already downloaded and saved. It can reduce the load on your server, especially for returning visitors and users that click around the site a lot or visit multiple pages, or are returning visitors.
W3 Total Cache Page Cache
Now that we have W3 Total Cache installed and activated, we want to optimize a few settings. From the Performance menu select the "page cache" section.
How to clear caches and finish installing
When you make changes to W3 Total Cache, site-wide settings, or other plugins, you will want to make sure to empty caches. W3 Total Cache will remind you of this with a warning at the top of the page to empty caches when you make relevant changes.
