5 Best WordPress Caching Plugins to Speed Up Your Website (2018)

Published on 24. August, 2018

Are you looking for the best WordPress caching plugins? Caching helps you speed up your WordPress site and boost performance. In this guide, we will share the best WordPress caching plugins for your site.

What is Cache?

Cache is a collection of temporarily stored data for quick access upon request. In computers, information is usually stored on hard disk. When it is requested, a computer needs to run several processes before the information can be presented.

Caching solves this issue by processing the frequently requested information and then storing it in a temporary storage or memory. This allows computers to access it the file quickly.

The same caching concept can also be used by WordPress websites to improve performance and make your website load faster.

You see, WordPress is a dynamic content management system. This means that each time a user visits your website, WordPress fetches information from the database and then runs several other steps before the web page is sent to the user’s browser. For details, see our article on how WordPress actually works.

This makes your website load slower when a lot of users are visiting it at the same time.

Caching allows your WordPress site to skip a lot of steps. Instead of going through the whole page generation process every time, your caching plugin makes a copy of the page after the first load, and then serves that cached version to every subsequent user.

How caching works?

Why is Caching Important

Caching is important because it reduces the load on your WordPress hosting servers and makes your website run faster. You need proper caching set up to improve your WordPress speed and performance.

A faster website improves user experience and encourages users to visit more pages. This also helps you boost engagement and the time users spend on your website.

A faster website helps you drive even more traffic to your website from organic search. Google gives a significant SEO advantage to faster websites which helps you rank higher in search results.
