Caching can be a complex topic, but it doesn’t have to be. This ultimate guide to WordPress caching for beginners will explain everything you need to know in simple, easy-to-understand terms.

Introduction: what is caching and why should you care?

Caching is a technique used to speed up the loading of web pages by storing frequently accessed data in a temporary location. This means a web browser doesn’t have to make a request for the same data over and over again. The most common pieces of code that get saved to users’ browser is the HTML, CSS, and in some cases even JS.

Depending on the caching plugin you choose and how your WordPress site is built it can have significant speed improvements. For most WordPress sites the improvement is around 1-2s in loading speed but some have even reported going from 4s to 1s or even under with their web pages’ load speed.

What is Cloudflare and how does it work?

Cloudflare is a content delivery network (CDN) and distributed domain name server (DNS) service that helps improve website performance and security. It works by caching static content on its edge servers located around the world, which reduces the load on the origin server and speeds up delivery. Cloudflare also provides security features such as DDoS protection and SSL/TLS encryption.

Cloudflare’s services use a global network of data centers, which are located in 120 cities in 30 countries around the world. Cloudflare offers a range of security features to limit the availability of cached content to an IP address.

Cloudflare also includes a free content delivery network (CDN) and distributed domain name server (DNS). Cloudflare’s CDN is similar to other commercial offerings, but Cloudflare’s CDN is free of charge.

On the other hand, if you want even more speed and want something that works perfectly with your WP Rocket, consider trying the RocketCDN which integrates quickly and easily with WP Rocket. Simply go to the RocketCDN tab and activate your subscription. If you’re not using WP Rocket you can simply install the plugin and activate the product there.

Varnish: another popular caching solution

Varnish is another popular caching solution that is often used in conjunction with WordPress. Varnish can speed up your website by caching static content and eliminating the need to send requests to the server for each page load.

Varnish is a great option for websites that receive a lot of traffic, as it can significantly reduce the load on your server. However, it is important to note that Varnish does not cache dynamic content, so you will still need to use a WordPress caching plugin for this purpose.

If you are considering using Varnish, be sure to consult with your web hosting provider to see if it is compatible with your setup. You should also consider using a caching plugin for any future WordPress websites that you build. There are several options available, so be sure to research which one is best for your needs.

How to set up caching on your WordPress site

Assuming you have a WordPress site that’s already up and running, there are only a few steps you need to follow in order to set up caching.
