The Best WordPress Speed Testing Tools (Free and Paid) of 2022

Check out our post about the best tools to check the speed of your website and other important metrics.

The speed of your website is extremely important. If it loads slowly, visitors will leave before reading much – or any – of your content. If it loads quickly, visitors are more likely to stick around and convert.

This is also why website speed is a major factor in Google’s algorithm. Websites that load quickly are almost always favored by Google and thus rank higher in search results (SERPs).

As such, fast loading websites benefit from higher SEO rankings, increased conversion rates, lower bounce rates, longer visitor retainment time and engagements, and better user experience. Which means it’s really important to have a fast website!

Likewise, the reverse is true for a slow website. Slow websites give your visitors a bad user experience and drive them away, negatively affecting your Google ranking. To avoid this, you need to learn how to test your site’s speed, in order to determine if you are losing potential traffic.

In this article, you’ll learn how to check your website’s speed with a variety of different free tools.

Metrics to Analyze

Speed testing tools analyze a number of parameters to determine your “score”, or the overall website’s speed. But fundamentally, they help you answer two questions:

  • How fast is my website?
  • If it’s slow, how do I make it faster?

Speed testing tools can tell you a variety of useful things, including:

  • how long the first text and image on your website take to appear on your website visitor’s screen
  • how long other pieces of content take to load
  • how long it takes your website page to become interactive

…and so on.

Website speed testing tools calculate this information by determining the Time to First Byte, usually known as TTFB. TTFB is the measurement of the time it takes for a web server to connect to a web browser and download the first byte of data.

Most tools have a “tips” area that suggests improvements depending on your particular situation.

A typical speed tool will perform the following actions:

  • Analyze HTTP headers/requests
  • Analyze total load time, page size and request counts
  • Identify the site assets that are causing slow pages
  • Check if the scripts on your website are minified
  • Identify large images that should be compressed to reduce their sizes
  • Detect render-blocking JavaScript/CSS
  • Check load speed using servers from different countries
  • Testing for Time to First Byte (TTFB)
  • Testing certain Core Vital Scores like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS)
  • Measure performance of your CDN (if you’re using one)

List of Website Speed Test Tools

There are a number of reliable free and paid website speed testing tools available, each with their own strengths and weaknesses. As such, we recommend using more than one.

That said, don’t spend too much time trying to get a perfect score. This is essentially impossible, no matter how many changes you make. Instead, just improve as much as you can in a reasonable amount of time.

The goal is to have your website load in two seconds or less.

 

Pingdom Speed Test

Pingdom has one of the most popular free website speed testing tools on the Internet.  It’s easy to use and allows you to simulate the loading time from more than 70 locations around the world.

After running the test, you’ll receive a score out of 100 possible points. Other data is shown in a waterfall view. It lists the total requests made to your website, load time and page size. You can filter the result by load order, file size, and load times. It helps you identify which files may be slowing your website such as CSS, JavaScript, or even the external domains these are loaded from.

Pingdom usually stores the results of all speed tests carried out for your website, allowing you to historically track any or all the speed improvements you have made overtime.

Price: While Pingdom is free, there are premium plans starting at $10 per month for those who need help monitoring the website’s performance on a regular basis.

Google Pagespeed Insights

Google Pagespeed Insights is a free website speed testing tool created by Google. Because Google takes into account page speed when ranking websites and displaying them on search results (SERPs), they created their own website speed testing tool. It can help website owners measure the performance of a page on both mobile devices and desktop devices.

A Google Pagespeed Insights score ranges from 0 to 100 points. The higher your pagespeed score, the better. As a general rule of thumb, you will want to achieve a score of 85 and above to have a “pass” mark.

The tool also provides you a report of each issue affecting your website loading speed, along with a detailed breakdown of recommended steps. Some core web vitals reported by Google Pagespeed Insights include Largest Contentful Paint (LCP), First Contentful Paint (FCP), and Cumulative Layout Shift (CLS).

If you care about ranking higher in SERPs, then you want to take this tool very seriously when optimizing your website speed.
