Final thoughts

The above plugins are some of the best speed optimization WordPress plugins available. However, it is difficult to determine the best one as every website is different and it may need a different range of caching.

So simply install the plugins you are considering and test how they affect the speed of your website using all these tools - GTmetrix, Webpagetest, Pingdom, Google PageSpeed Insights, and Think With Google Mobile Speed Test. Additionally, do read the documentation guide for each plugin to get a better understanding of all the features at your disposal.

Sometimes a major reason for slow loading websites is because of hosts. So make sure you choose a good one. Remember, you usually get what you pay for. If you want to learn more about some of the top WordPress hosts, click here.

Hosting providers like WPEngine do not support speed enhancing plugins such as WP Super Cache, WP File Cache, W3 Total Cache and WordFence as they do not work together with their custom caching environment. WPEngine’s official page states that they take care of speed-related issues and that users of their hosting service needn’t worry about it. But WP Rocket is compatible with WP Engine. It is now part of WP Engine’s preferred marketing program.

Whichever plugin you choose, make sure that the settings are supported by your web host, and don’t make any changes without backing up. To find out more about how to optimize your website, take a look at our article on Website Speed Optimization Hacks for WordPress
