Best and Free Website Speed Testing Tools

We all know how critical is the speed of a website for it to be successful. As a developer, I like to use some of the standard free website speed testing tools to help me with my web development.

Moreover, website speed improves the overall user experience. I have emphasized a lot about speed on my traffic building article as well as in the WordPress SEO checklist.

It is universally true that a fast loading site or blog has an advantage in SEO rankings. Search engines prefer sites with a better speed index. Such a website or blogs get high conversions, lower bounce rates, and excellent engagement.

There’s a long list of benefits of fast loading websites. The problem is how to attain a good speed in the midst of using Adsense and other third-party scripts.

What are the available tools to test site speed and make changes? In short, what to analyze in a site speed test and how to improve the red flags in it.

I use and recommend these free website speed test tools.

Before we get on to the list of site speed testing tools, it is essential to know what to analyze. Yeah, if you don’t know what you must look for after a test, then what’s the purpose of testing in the first place. Hence, let’s first see what a speed test tool helps you analyze.

Things I Analyze for Website Speed Testing

There are certain things that I analyze when testing a website for speed. Remember, the aim is not to get a complete score of 100 on Google speed test but to make sure the site provides a good user experience.

So let me share what data I look at when analyzing a website speed:

• Scripts issues causing slower load time. Moreover, I also check if the scripts are minified, combined, etc.
• Are all images in the WebP next-gen format. I use Imagify to reduce image size as well as get the WebP version. Finding large images resulting in bottlenecks.
• Validated HTML, which isn’t totally for speed, but then it also helps with better user experience. So I use W3Validator to optimize and correct the HTML.
• Ideally, I never load any custom fonts on my site. I like to keep them with all system fonts and Arial. However, for clients, I recommend them not to use many customs or Google fonts.
• Avoid render-blocking JavaScript or CSS. However, in some cases, if there is a jQuery needed to load right at the top, I load it via Google CDN to make full use of the cache.
• Testing Time to First Byte (TTFB)
• Analyzing total load times, page sizes, and the number of requests.
• HTTP Header checks when doing 301 redirects.
• Verify assets are loading correctly from CDN, especially the images loading inside the CSS file.

Now that you know what you should be looking at in site speed test results check out the list of tools below. Each tool is unique and offers a basic understanding of the concept of website speed and performance.

So here are the website speed testing tools I go with:
