Why Do You Need a Cache Plugin On WordPress?

There are many ways to optimize your WordPress website, and caching is one of them. Caching plays an important role in website optimization. Things like images, videos, scripts, and fonts can drastically improve your website’s looks and appearance, but at the same time, they increase the website size as well. This thing increases the website’s load time, and users can leave the website if it’s not loaded fastly.

Thankfully, using a caching plugin in your WordPress website can improve the site speed. In this post, I will cover everything related to caching and why you need Caching Plugin for your WordPress website. Here’s an overview:

What Is Caching?

Caching creates a static version of your website and serves it to the visitor. Static pages load quickly in web browsers, which drastically improves the performance of the website.

Whenever someone visited your website, then his/her web browser contacts your Web server. After that, your WordPress installation contacts the database to fetch your posts and other data on your website. In the end, the Web server instantly compiles the data and returns it to the web browsers in an HTML page form.

We can say that your website data travels around three computers to send the information back to the user. Caching can significantly speed up the data transfer between these computers by taking some abbreviations.

When a user visits your website, some of the files like the banner image and static page will get saved on his local drive until you changed something on your website. When that user visits the website, the static page and images that were saved in his browser render, and the website loads up too quickly. This way, the user’s web browsers didn’t re-request each file to load the website, which reduces the server load.

After reading the above statements, you probably get an idea about Caching, and it is important for your Website. Caching is all about reusing the saved data from last requests to speed the rendering of your WordPress website. It minimizes the data that flows between the user’s web Browers and your Website server, which boosts the site speed.
