There are many free and premium WordPress caching plugins available but it is very important to know which suits your requirement the best.
It’s not W3 Total Cache or WP Super Cache
The most talked about WordPress caching plugin is W3 Total Cache. It comes loaded with so many options and features. I have shared the configuration settings for W3 Total Cache and I can tell that it is not easy to understand and setup the plugin. If you are a beginner or not so familiar with server settings and performance parameters, I will not recommend this plugin to you.
WP Super Cache is another popular caching plugin which is easy to use as compared to W3 Total Cache but is not the best. I am a big fan of WP Super Cache because of the CDN integration and Super Cache feature but I always missed the HTML, CSS and JS minification and concatenation feature. To get these things, I was forced to install Autoptimize plugin along with Super Cache.
And the Best Free WordPress Caching Plugin is: WP Fastest Cache
I installed WP Fastest Cache on WP Optimus and here is the result from GTMetrix:
WP Fastest Cache plugin is having everything that most of the WordPress sites need for performance improvement. And the most important thing is, it comes with simple UI which anyone can understand.
User Interface Makes Complex Things Simple
W3 Total Cache is having more features than Fastest Cache but still I recommend WP Fastest Cache because of it’s UI. A very simple to use panel with even powerful options appearing as a checkbox.
Minify and Combine JS, CSS
Well, if your site is loading multiple JS and CSS files, check this option on setting panel to minify the files as well as combine to reduce the number of DNS requests.
GZip and Browser Caching
To serve the pages fast, you can enable GZip option which is recommended by Google PageSpeed as well as YSlow. And to leverage the browser cache, enable the “Browser Caching” option which will again improve your site speed score on GTMetrix.
Settings page of WP Fastest Cache comes with CDN tab to allow you enable CDN services. CDN (Content Delivery Network) loads the static files like JS, CSS, Images etc. from the distributed servers to serve the pages fast. YOu can use the paid services like MaxCDN, Cloudflare or just enable the free service named Photon which comes with JetPack plugin of WordPress.
If you are not using any caching plugin on your WordPress site, check the GTMetrix report and Pingdom report. Install WP Fastest Cache plugin and re-check the same. If you see improvement in Page Load Time and Score, like and share this post with your friends and colleagues.
