Best Tools to Test Website Performance in 2024

Improving your website speed and web performance is no longer optional, especially for ecommerce businesses. A slow-loading, unresponsive website can lead to frustrated users, low retention, high bounce rates, and ultimately, lost revenue. But before you start optimizing, you need to know what you should work on – this is where you need a tool to test website performance.

In this comprehensive article, we’ll provide a detailed comparison of the top tools to test website performance in 2024. By the end of this post, you should have a clear understanding of which tool is the best for your business and how to leverage it to optimize your website’s performance. Let’s get started!


What is the best way to test website performance?

When it comes to testing website performance, there are several key metrics that you should focus on. These metrics provide a comprehensive view of your site’s speed, interactivity and responsiveness, all of which are key factors contributing to the overall user experience.

Page load time: This is the time it takes for a web page to fully load, from the initial request to the moment when all resources (such as images, scripts, and stylesheets) have finished downloading. Ideally, your page load time should be under 3 seconds, as studies have shown that longer load times can lead to increased bounce rates.

Core Web Vitals: Introduced by Google, Core Web Vitals are a set of three key user-centric web performance metrics. These include Largest Contentful Paint (LCP), which measures the time it takes for the main content of a page to load, Interaction to Next Paint (INP), which measures the time it takes for a page to become interactive, and Cumulative Layout Shift (CLS), which measures the visual stability of a page.

Resource timing: This area provides detailed information about the loading times of individual resources (such as images, scripts, and stylesheets) on a web page. By analyzing resource timing, you can identify specific assets that are slowing down your page’s load time and take steps to optimize them.

Hence, there are website performance testing tools which are able to evaluate some, or all, of these metrics. Also, it is essential for your tool of choice to be able to test across different devices, locations, and browsers. This will help you identify any inconsistencies or issues that may only be present on certain platforms or in specific regions.
