When it comes to the speed of a website, this feature alone can make or break a website’s success. Faster loading websites tend to benefit from higher SEO rankings and lower bounce rates which leads to an overall user experience. This is why it is important you take advantage of useful tools to enhance your site’s speed. Running a website speed test can help you analyze a lot of things such as checking minification of your scripts or for analyzing HTTP headers and verify assets that are loading correctly from the CDN.

Before running a speed test, there are two terminologies that you should be aware of. The first one is time to first Byte (TTFB). This measures the responsiveness of a web server and talks about the time it takes a browser to start receiving information after it must have requested it from the server. The second terminology refers to Render-Blocking Javascript & CSS. These are files that are preventing or keeping your pages from loading as quickly as possible.



Google PageSpeed Insights

This is one of the most popular tools used by millions to test the speed of their website. It grades a website on a scale of 1 to 100 – with the higher number reflecting how optimized the site is. Based on industry standards, anything above 85 means your website is performing really well. Google PageSpeed insights give insights for both desktop and mobile versions of your site and you can also view recommendations on how to improve your sites such as what you need to do to the images and the type of content you need to remove or change to reduce page load speed. With this free tool, you can improve the performance on time to above the fold load and time to full page load.

Pingdom Speed Test

Another useful tool for measuring the speed of your site is Pingdom. It is well known too. This tool creates reports divided into different sections which include a breakdown of your page analysis, history, devices and performance grade. With the analysis gleaned from Pingdom, you can easily compare your asset size against your domain, check out the request per domain and the type of content that gets the most requests. Another cool feature about Pingdom is that it allows you test your website from different locations from Texas to Melbourne to Stockholm so you can have a feel of what other customers go through when they try to visit your site.

GTmetrix goes a step further by creating reports on your site’s Page Speed and YSlow metrics. With this tool, you will be able to see the PageSpeed. Once you register on GTmetrix, you can test your site speed from seven different locations and chose different browsers as well as compare and contrast your website performance against various connection types such as cable as against dial-up to see how they all affect your page loads.

KeyCDN Website Speed Test

This is a website speed test tool created by KeyCDN which allows you to gain insights into how your website performs and it offers 14 locations where you can choose from to test your website performance as well as the option for making your test private or public. There is a waterfall feature and a visual website preview at the bottom where you can see how many HTTP requests were made to your site and the load time.

WebPage Test

This is quite similar to some of the tools already reviewed here but it has more locations where you can test from and more browsers as well. WebPageTest offers 40 locations where you can test your site speed performance from and 25 browsers to choose from. It uses a grade from F to A based on performance test on key areas of your site such as the FTTB, caching and effective use of CDN. WebPageTest has a different approach to the rest of the tools in this article as it uses a unique approach to its speed test. It has what it calls a ‘first view’ and a ‘repeat view’ which is great for diagnosing the 1st time DNS lookup delay.
