Four Top Free Tools to Test Your Website Speed

testing website speed

Eight out of ten experts say that the biggest WordPress flaw is speed. WordPress is slow compared to the needs of its users, despite the endeavors of the brave development community behind it. You have to fix this problem by yourself until WordPress becomes faster. 

It isn’t only the WordPress core files impacting the loading speed. Your site file size, the hosting platform, the theme, the plugins, or the caching system all matter a lot. Luckily, you have at your disposal free, effective tools to test your website speed and make it load faster.  

Check out the following paragraphs to learn more about these tools and discover which one works the best for you.

How to check my website speed?

Apparently, it’s a trivial task to test your site loading speed. Yet, there are a few tricks that help you to correctly asset your site. 

First of all, make sure that your Internet connection is stable. It depends on the local infrastructure, but some connections are not stable and may skew the results. Second, use one tool at a time. The tools to test your website speed may have similar or identical metrics, but they are not the same in most instances. Don’t compare the rating of tool A and tool B! The tools might measure the same metrics—let’s say, First Contentful Paint—but the location test and type of Internet connection matter.  

Thirdly, do more than a single test. If possible, perform the test two or three times from the same testing location. Last, but not least, verify the caching plugin or the content delivery network used. Make sure that your site is cached and the delivery network is properly configured.

Now, let’s analyze each recommendation for testing the website speed!

Best Website Speed Checkers

Google PageSpeed Insights

Website loading speed is a ranking factor in the Google algorithm. A faster website means a better ranking. Hence, PageSpeed Insights should be a top priority, as a good score means that you satisfy Google’s expectations in terms of speed. There are many other reasons to use PageSpeed Insights as well.

Your site gets a grade, from 0 to 100 points, for both mobile and desktop. A 100-point grade means that your site is perfectly speed optimized, which is pretty rare on mobile. Google rates any grade above 90 as good, while any grade from 50 to 89 requires improvements. Do everything possible to avoid a grade below 49. 

The grade of your site is based on a few metrics, including First Contentful Paint, Time to Interactive, Speed Index, Total Blocking Time, Largest Contentful Paint, and Cumulative Layout Shift. You should study what these metrics represent if you want to be a speed optimization expert.

Alongside the grade and the metrics, PageSpeed Insights provides a list of things to fix on your site. Follow these recommendations, and you will certainly speed up your website.

The drawback of PageSpeed Insights is that you don’t have any control over the testing conditions. For instance, you don’t control the testing location, the agent used, or the type of Internet connection. Despite that, you should always take a look at PageSpeed Insight if you want a better rank in Google searches.


  • Free of charge, no premium version
  • A comprehensive site diagnostics + improvement suggestions 
  • User-friendly interface


  • Lack of customization options 


gtmetrix website load test

GTMetrix provides you with the most comprehensive report on your website performance. You can use it as a non-logged-in user, as a logged-in user, and as a premium user. Use it without logging in to get a complete analysis from a test location in Canada that uses a Chrome browser on an unthrottled network. By creating a free account, you can choose from more locations (including Vancouver, Hong Kong, London, Mumbai, San Antonio, Sidney, and Sao Paulo). Additionally, you can select the type of Internet connection.

Unfortunately, the desktop version of Chrome is the only browser option for all tests. The premium accounts benefit from even more testing locations, multiple types of browsers and devices to access the website, and custom Internet connections. Yet, the more important feature of the premium account is the test of the mobile version of your site.

You get a lot of actionable data by testing your site with GTMetrix, even without an account. GTMetrix Grade and Web Vitals are the strategic aspects revealed by querying your website.
