Best Website Speed Testing Tools in 2024

Speed is everything!

Web page load time is a critical component that determines online success or failure. Desktop sites have between 4 and 9 seconds to grab interest before the customer moves on to another site. Advancing technologies have shortened the attention spans of consumers. 53% of mobile websites have less than three seconds to capture the eye of a customer. If these numbers are not startling enough, every second in the delay of a page load yields 11% fewer visitors.

Website speed testing tools are essential methods for discovering and monitoring page loads of a website. Here are 13 of the best tools for testing website speed.

1. SE Ranking

This comprehensive SEO platform has its website speed analysis tool. You can see it in the Website Audit section, which has a dedicated Core Web Vitals category.

The advantage of SE Ranking is that it is not just a page speed checker. After receiving data about the problems, you can granularize the report and see the specific pages that require your attention. The service will provide you with both the best website speed test and tools to improve the current situation:

  • Detection of unoptimized JavaScript and CSS code in the Issue Report section;
  • Evaluation of the Text-to-HTML ratio, which shows the efficiency of the code;
  • Search for unoptimized multimedia in the Found Resources section;
  • Evaluation of hosting capabilities;
  • Detection of problems with the CMS, individual plugins, and other elements of the program base;
  • Search for redirects that slow down page loading. 

Website load speed test is included in the list of regular checks that can be run manually or automatically. If the system detects a significant deterioration in performance, it will send you an email warning. By taking the necessary measures in time, you minimize the impact of such problems on the effectiveness of SEO. 

The Website Audit module is available as part of a basic SE Ranking subscription starting at $44 per month.

At first glance, it may seem that ContentSquare Speed Analysis exactly replicates the functionality of Google’s standard page speed testing tool. It also focuses on the Core Web Vitals metrics and displays the test results in a simple, intuitive graph. 

However, just one click on the indicator you need makes a big difference. ContentSquare Speed Analysis provides as much detail as possible, allowing you to find problems in the rendering of a particular image or the poor optimization of a certain code fragment.
