Steps to Run a Website Speed Test in a Right Way

Now that we have accessed the 15 best website speed test tools, it’s time to understand how to properly test the speed of your website.

Step 1: Turn on Website Caching

Whenever you check the speed test of your website, make sure caching is turned on. Website cache helps the server to find out the requests from the repeating users, which will then allow them to get a faster loading site when they visit again.

Step 2: Enable Content Delivery Network (CDN)

Turning on your website's CDN is another great way to increase load times. It delivers the content from a server location that is closer to the user.

Step 3: Use Multiple Test Locations

Depending on the website that you are testing and where the speed test will be run, it could affect the results significantly. And, the above list of website speed test tools allows you to test from different locations worldwide.

Step 4: Run Test Multiple Times

It is a great idea to run the test multiple times. If you're testing your website once then you are not checking the speed from a cached version of the site. So, it is recommended that you make sure both the cached and un-cached versions of your site have a fast loading speed.

Step 5: Run the Test on Multiple Devices and in Different Browsers

It is also a great way to run the speed test on multiple devices and in different browsers because the website loading time varies depending on the device or browser your visitors are trying to access your site.


In the above list, we have listed down the best website speed test tools. Now it depends on your requirements and preferences. For example, if you are a beginner then we recommend you to use Pingdom for checking the website speed which is simply easy to use. And, if you want to test your site using Google's official website speed test tool then Google PageSpeed Insights will be your best bet. But, if you're a professional user then best to go with the WebPageTest tool.
