Do you know that 46% of people say the thing they hate the most about browsing the web is waiting for pages to load? The conversion rate drops by 7% when load times are delayed by 100 milliseconds.

As a result, page speed is essential, and you want to boost it as much as possible. So you’re searching for the best caching plugins to help you improve the speed of your website even more.

It’s not a problem.In this post, I’ll test the best caching plugins so that you can figure out which one is right for you. But before we get into the root of the matter, let’s take a quick look at what a caching plugin is and why it’s important for your website.

What is Cache?

The cache is a collection of data that is stored immediately for fast access when needed. We cached data in the hard disk on our local computer, and when the information is required, it is displayed after performing various processes.
Caching works by processing frequently requested data and storing it in temporary memory. As a result, computers can easily access the file when it is needed.

The same things happen in WordPress. Each time a visitor visits your website, WordPress fetches data from the database. So here it comes to caching plugin when visitors first visit your site, Caching plugin saves the data. Then again, the viewer visits your website, WordPress does not fetch the data from the database from temporary memory that is what the cache plugin collected.

Caching helps you to skip several measures on your WordPress account. Instead of collecting data from a database, your caching plugin creates a copy of the website after the first load and then serves the cached version to your user every time.

Why is Caching Important?

It lessens the load time on your WordPress hosting servers and makes your website run a lot quicker. Your website’s speed and performance will increase if you set up your cache carefully.Websites that load faster boost the user experience, increase conversions, and enable users to visit more pages. It eventually raises the number of people who visit your website.

The speed of a website is a significant ranking factor. If you make your website quicker, Google will pay attention to it and offer you an advantage in terms of ranking. Mr. Google will still ignore you if your site is slow to load, regardless of how great your content is.
