How to Improve WordPress Website Performance by Removing Unused JavaScript

As a WordPress website owner, have you ever noticed that your website speed is slow or that some pages take forever to load? The chances are that the problem may be due to the presence of unused JavaScript on your website. In this article, we will discuss the impact of unused JavaScript on your website’s performance and how to remove them to improve user experience.

Why Do Unused JavaScript Scripts Affect Site Performance?

Unused JavaScript is a common issue on WordPress websites, and it can significantly slow down your website’s speed. While JavaScript contributes to creating an interactive user experience on your website, it can also lead to performance issues when the scripts are not optimized correctly. The problem with unused JavaScript is that it adds unnecessary code, which increases the site’s loading time, leading to a poor user experience.

How to Remove Unused JavaScript in WordPress

Removing unused JavaScript scripts may seem daunting, but it is a straightforward process when you have the right tools and procedures in place. Here are the steps you can take to remove unused JavaScript in WordPress:

Step 1: Evaluate Your Website’s JavaScript Scripts

The first step is to evaluate your website’s scripts to identify any unused JavaScript. You can use a website auditing tool such as Google’s Lighthouse or GTmetrix to scan your website and provide detailed reports on issues affecting your website’s performance. Alternatively, you can go through your code manually and identify the scripts that are not being used, although this is a time-consuming process.

Step 2: Remove Unused JavaScript Scripts

Once you have identified the unused JavaScript scripts, the next step is to remove them from your WordPress website’s code. This process can be done by using a plugin, such as Asset CleanUp or WP Minify, to remove unused JavaScript scripts automatically. If you are comfortable with coding, you can remove unused JavaScript scripts from your WordPress theme or plugins. Ensure you keep track of the scripts you remove to avoid breaking any website functionality. It is also advisable to create a website backup before making any changes to your code.

Step 3: Optimize Your Website’s JavaScript

Removing unused JavaScript scripts is one step in optimizing your website’s speed and performance. Optimize the remaining scripts to improve your website’s functionality and reduce loading time. Here are some tips for optimizing your website’s JavaScript:
  • Minify Your JavaScript
  • Load JavaScript Asynchronously
  • Use a Content Delivery Network (CDN)
A content delivery network (CDN) can help improve your website’s loading speed by delivering your JavaScript files from servers closer to the user, reducing latency.


Removing unused JavaScript scripts is essential in enhancing your WordPress website’s speed and functionality. By evaluating your website’s JavaScript, removing unused scripts, and optimizing your remaining scripts, you can significantly improve your website’s performance. Ensure you employ other optimization techniques, such as image optimization and caching, to enhance your website’s performance further.
