How to Do a Website Speed Test

If you run a WordPress website – either for yourself or a client – it’s important to regularly run website speed tests.

Website speed is a significant ranking factor in Google’s algorithm which means that the faster your site is, the better it will rank in SERPs. This means that website speed is important for SEO. Aside from that, website speed also impacts the user experience your site delivers. People are more likely to stay on your website if the pages and blog posts on it load fast.

From a business standpoint, an unavailable, slow, or broken website can hurt your brand. This, in turn, negatively affects your conversion rates.

So, checking out your WordPress website’s speed is important because it helps you identify areas of improvement. This way, you can take steps to speed up your website for your visitors.

However, if you’d like to take the DIY approach, you can run website speed tests on your own. Because the testing tools available on the Internet measure website speed in different ways, you shouldn’t be concerned if you get different results from Pingdom than you do from GTmetrix or PageSpeed Insights.

What is important is that you pick one tool and stick with it. This will give you a clearer picture over time about your WordPress website’s speed and make it easier to compare results. As a result, you’ll know how different technologies (themes, plugins, add-ons, and integrations) affect your site’s speed.


GTmetrix is one of the most popular website speed test tools that you can use for free. It’s easy to use and gives you a wealth of information in each speed test you run.

This includes website speed metrics like page load time, total page size, the number of requests, and performance score.

GTmetrix also displays a list of requests in a waterfall chart. This makes it easy to identify individual problem areas and take steps to correct them. You can also filter requests in the waterfall chart by HTML, CSS, JS, XHR, fonts, and images.


Monitoring your website’s performance is critical for ensuring your website is loading the way you expect it to. Even the best-performing sites experience occasional blips. So, it’s important to regularly monitor your website to make sure its performance is top-notch.

For example, the Speed Visualization is an “intervaled capture of your page load”. This helps users gain deeper insight into their website visitors’ experience.

Similarly, the Waterfall Chart provides a request-by-request visualization of the page load.

When you re-test your website, you’ll be able to see even more graphs under the History tab. It provides graphs for page metrics, page sizes and request counts, and page scores.
