Best WordPress caching plugins for speed

You will know by now the importance of speed on a website and a caching plugin is a very simple yet powerful tool that should be installed on every site. But what is a caching plugin and why do you need it? We look at some of the best WordPress caching plugins for speed and how you can use them on your website.

As Google now factors site speed as part of their algorithms to determine where to rank your site in their results pages, site loading time is more important than ever.

That’s where caching plugins step in.

So what does a cache plugin do?

A cache plugin stores data from visitors. Information such as the layout and CSS of your site means that the next time they visit, the old cached data is at hand to speed up load time. In other words, a visitors computer will remember that it was on your site previously and won’t need to load all the information from scratch.

This is where caching plugins come in. There are a vast array of plugins, in both paid and free versions. Like anything, you usually get what you pay for. However, some of the free versions are perfectly adequate and will do the job just fine. Premium plugins such as WPRocket require a yearly fee but have many extras over a free plugin.

Go through the settings, in most cases, the default settings are perfect to begin with. Its a simple matter of installing, activating and make sure the plugin is switched on.
