What Is Caching?

Website caching is a technology that compresses your website pages to reduce its size and make your website load faster. Simply put, it creates lightweight static HTML versions of your PHP pages to allow your website visitors to load your web pages faster while also reducing your server resource usage.

There are several different types of caching technologies, including website caching, which you’re in control of. Then there’s server-side caching, which is mostly available with managed WordPress hosting platforms. And there’s also code minifications and compression technologies that help reduce page load times as well.

For a long time, many people avoided website caching because it required editing website files and editing core WordPress code. Now it’s as easy as installing a plugin and clicking a button. All thanks to WordPress plugins.

Why Is It Important?

The loading speed of your website directly affects the success of your business. If your website takes more than 3 seconds to load, you will lose most of your website traffic.

In fact, Google recently released a new search update that promotes websites based on loading speed by ranking the fastest websites higher on search results pages.

Needless to say, your website speed is a critical factor that will make or break your business website.

Installing a caching plugin is the first step you can take to speed up your website and make sure your site ranks well in search engines.
