A fast website speed is always good for SEO and the user experience.

Bounce rate increases with a long page load time, which is the rate at which the users tend to exit the site before they click through any other page of the same website. is among the best all-purpose website performance plugins.

How To Properly Run A Website Speed Test

How is a website speed test done?

In order to get started with a website speed test, you need to make sure that you have Caching and Content Delivery Network (CDN) running on your site. Sometimes, there is traffic on the internet that may slow you down, while other times, you can run through it quickly.

There are numerous factors responsible for affecting the quality and accuracy of your website speed test online. Therefore, these tests should be run in a thorough manner with the help of the website speed testing tools before you begin to analyze your data.

  • Choose the location of your test

When you are running a website speed test, you need to select the location that is nearest to your site server. This is because your website speed test tools offer multiple locations from where they are able to test the site. It is worth noting that your site location and the test can impact the results to a great extent.

If your website takes around two seconds to load and your server is in New York, USA, then it may take nearly five seconds to load from any other location, say Australia. This all happens because of the server latency. When you keep the exact location, you can manage the factors constantly, and therefore, you can get consistent website test speed results.


  • Run multiple tests

When you are optimizing and testing your website in order to get the best speed, then you have to make sure to run the tests many times so that you can build up a cache. When one runs the test for the first time with a website speed test online after configuring your site, then there are chances that the content isn’t cached on your web host, and the site will already appear relatively slow.

The test result values will also be varying most of the time because the tools might have some noise between the measurements. One should never be hung up on these metrics and only investigate if the website is taking more than 20 seconds of time to load. It will probably be fine if the difference is of just a few milliseconds.

With the help of the website speed test tools, you can run the test in a number of browsers on both your desktop and mobile devices to check if the website’s speed is constant across each of the platforms.


  • Configure your site in a proper way

The most common of the issues faced by the majority of the slow sites are hosting, images, plugins or themes, JavaScript rendering, redirects, and large files. You have to make sure that the website caching is turned on before you start running the website speed test with the help of the website speed test tools.

This will surely be helpful for you to test website caching and how effective it can be to improve your site’s performance. You have to keep in mind that some of the caching solutions store the cache when the user requests the page. Therefore, the cache may take some time to build and can get expired by the time you are able to run the tests.

Many experts recommend to be the best plugin as it is helpful for you to set up the cache with just a few clicks and without going into details regarding any of the technical stuff. The best thing about Pagespeedy is that your website’s cache is built in a proactive manner that is helpful to improve the performance of your website.


  • Test the internal pages also

The site owners tend to forget to run the website speed test of the internal pages of the site most of the time, including the homepage, product pages, blog posts, etc. The speed of the website varies between the pages because every page contains a different set of resources like HTML/CSS, images, and JS.

Therefore, it is necessary to always run a website speed test on a few of your website’s internal pages. As far as the website speed test tools are concerned, some offer website speed test for free while others are paid versions. You have to makes sure that the pages are always consistent and have an acceptable page speed.

Understanding the results of your website speed test

The time it takes to load your website is considered the most critical parameter that you should be looking into. This is a significant parameter as it affects the users the most, and if your website is taking a little longer time to load, then there are chances that your users or customers may have a wrong impression of your brand and think of your website to be of low quality.

You need to look at the drill-down reports if your website is taking longer than two seconds to load and find out the resources that are taking a long time to load. Typically, these are the scripts loading from the third-party websites, stylesheets, images, video embeds, and much more. As a user, you should be making sure that the images are served from your CDN service or the cache.

The second most important parameter that needs to be tested is the TTFB or Time to the first byte. If your web server is showing a slow time to the first byte continuously, then it is time for you to talk to your web hosting company.


Best tools for running a website speed test online

It is not necessary to try your website with just one tool. In fact, you can use various tools and run a number of tests in order to be thorough.

However, it is always recommended for the users to use the tools to improve the website’s performance.
