8 Best WordPress Cache Plugin to Boost Site’s Performance

Are you seeking the best WordPress cache plugin to boost your website’s speed?

Fast-loading websites greatly impact your site’s user experience, improve the site’s SEO, and get a better conversion rate.

It’s the most important factor that no site owner can overlook if they seriously want to boost their site’s ranking on SERPs because Google considers site speed as one of their ranking factors to measure the ranking position.

In this article, I will share the best WordPress cache plugins to speed up your website and improve its performance to help you boost your site’s ranking and drive more organic traffic from Google.

Are you ready to get started?

What Is Website Caching and How Does It Work?

A caching plugin creates an HTML (static) version of your web page to make it easier for future visitors to access. Usually, a page request takes many steps to fetch the requested data, such as PHP processing, fetching the data from the database, and many more resource-consuming tasks on the server side.

But thanks to a caching plugin, you can eliminate these unnecessary roundtrip data processes and improve page loading times.

What A Cache Plugin Does?

A caching plugin makes it easy for future visitors to get faster access to your website content by eliminating the steps the browsers take to generate dynamic pages. It generates a cache version copy of your webpage content and stores the data so future requests can be delivered faster and prevent your server from overloading.

This process makes your site load faster by reducing your server load from unnecessary requests to the database and saving your content to HTML files. Page caching saves some loading times for the next user request.

Why Do You Need a Caching Plugin?

A cache plugin is a must-have WordPress plugin to enhance your site’s performance. Using a cache plugin is the best way to make your site’s loading faster, improve the site’s user experience, reduce server loads, increase the site’s ranking, and boost your conversion rate.

Let’s look at each benefit, and you’ll understand why you need a cache plugin.

Benefits #1: Optimize Performance and SEO

When someone visits your website, many processes start automatically behind the scenes, such as reading the CSS files, loading and executing the JavaScript, fetching data from the database, etc.

All of these tasks are necessary to display a web page correctly. However, it requires a certain amount of time for the user to wait for the process to get the correct web page display. 

If your site takes a long time to load, it hurts your website, Core Web Vital, and your page ranking on Google.

Here is an example: When SmartFurniture decided to speed up its website, the company noticed that they’d gained three benefits:

  • A 20% increase in organic traffic.
  • 14% increase in page views
  • Improving the search engine ranking by an average of 2 positions.

Benefits: #2 Improve Conversion Rate

Caching not only makes your website load faster but can also lead to sales and conversions. An interesting case study by mPulse Mobile shows that a website with an average 2.4s loading time can lead to almost a 2% conversion rate.

As you can see below, the faster the loading, the better the conversion rate.

Benefits: #3 Improve User Experience (UX)

Caching is one of the most effective speed optimization techniques to speed up your WordPress website and have a fast-loading page. The infographic also shows that 67% of smartphone users are expected to load pages in less than 4 seconds.

Caching can also help reduce server load and bandwidth consumption by optimizing database queries. These can save some of your server memory and improve the time to the first byte (TTB).
