Factors to Consider While Measuring Your Website Speed
Before you start using Gtmetrix and run a site speed performance test, you need to make sure that you get accurate results.
The primary purpose of testing is to get precise information about your site’s performance. An accurate result will further help you in decision-making about what needs to change.
Therefore, let’s look at the parameters you need to consider while running your website speed test.
- Multiple tests: Making changes based on the results of one test does not make sense because the results can vary due to various factors, including traffic. Therefore, we recommend conducting multiple tests at different intervals for better accuracy.
- Location of the test: Location plays a vital role in the test results. Therefore, if your website has a local audience, you should set the nearest location for conducting the GTmetrix speed test. However, if you have a global audience, you must perform the test with various regions around the world near your visitors. This will ensure that you get accurate results.
- Test subjects: Undoubtedly, testing your entire site is excellent. However, you must test multiple pages and posts for the greatest accuracy. Testing individual posts and product pages will give you an in-depth analysis of which pages or posts need to be optimized.
- Test device: Most site owners only test their desktop site and ignore mobile users. Your site is accessed by a large amount of mobile traffic. Additionally, the site’s connection speed varies on mobile devices compared to the desktop version. Many mobile devices take longer to load the JavaScript, which might result in slower load times. If you want accurate data of how your site will load to mobile, you must conduct speed tests for the same. With the premium version of GTmetrix, you can test your site on mobile devices.
All the factors mentioned above are crucial to get accurate data. However, your primary purpose should be to improve your site’s performance rather than focusing on the test’s score. To make a positive impact, consider the above factors.
How to Easily Run a Speed Test With GTmetrix
Using the GTmetrix tool is no rocket science. The easiest and quickest way to run a GTmetrix speed test is by visiting the GTmetrix homepage and pasting in the URL of your site.
Once you have pasted the URL, click on the Test your site option.

However, we would suggest that you register for a free GTmetrix account before doing the test. Doing this will allow you to configure settings.
If you run a test using the public version, your speed test will use different configuration settings such as from different tests from various test locations, for example from Vancouver, Canada using a desktop Chrome browser and an unthrottled connection.
Therefore, we recommend signing up for an account, or else you won’t be able to change the location. Once you sign in to the account, you get the option to choose between six various test locations, which are:
- Dallas, USA
- Mumbai, India
- London, UK
- Sao Paulo, Brazil
- Hong Kong, China
- Sydney, Australia
Besides changing the location, you also get the option to change the connection speed and mobile test device. Additionally, you can explore the analysis options to understand the functionalities of your GTmetrix speed test.

GTmetrix also gives you the chance to present a video of your homepage loads and options to avoid ads on the testing pages.
When you are done changing the configurations, you can run the test by clicking on Analyze. Once the test is done, you will see the results on your screen for page loading time and a performance score.

Below the score and page load time, you will see a detailed result with six different tabs that we will learn about in the next section.
A Detailed Guide to the Advanced Analysis Options of GTmetrix
Getting a basic snapshot of your site’s performance is excellent. However, the six tabs give in-depth insights into your website.
All six tabs contain crucial information about your site’s performance. Additionally, each of these tabs comes with multiple suggestions to improve performance. Let’s have a look at these six tabs.
PageSpeed
PageSpeed is a default tab after the GTmetrix speed test. The tab offers suggestions using Google’s PageSpeed rules including image dimensions, leverage browser caching, and minifying HTML. For each of the 26 rules, your score ranges from 0-100.
These individual scores are then added up to generate an overall score for your site. You can click on the arrow to provide additional details about the element causing trouble to your website’s performance.
Remember, some of the suggestions are more crucial than others, which you can assess quickly using the priority column.
One of the most vital things to remember is not to chase the percentage. Sometimes they can be misleading. Instead, you need to focus on the load speed given in seconds.
Your main goal is to reduce the seconds rather than going after the percentage. Another critical point to remember is that you can have a blazing-fast website speed without getting the perfect score.
Besides, some of the common PageSpeed problems you will come across are optimizing images, leverage browser caching, server scaled images, specify image dimensions, Minify HTML, CSS, JavaScript, landing page redirects, and more.
YSlow Tab
YSlow is similar to PageSpeed as it provides various recommendations to improve the website’s speed. However, the suggestions provided by the YSlow tabs are different than for PageSpeed. The set of rules is shorter and different.
YSlow tab uses 19 sets of rules, and similar to PageSpeed, you get scored based on each role. These scores are then weighed out on the average of each score. Similarly, you can click on the arrow to learn the details of each rule.
The most common recommendations in the YSlow tab you will encounter is Compress Components, Avoid URL directs, using a CDN, fewer HTTP requests, use cookie-free domains, reduce cookie size, configure entity tags, Minify JavaScript and CSS, Make AJAZ cacheable, avoid CSS expressions, and more.
Remember, once again, your website can provide 100% faster loading times yet face low scores. This should not be a concern for you; therefore, we highly recommend focusing on the page loading time seconds.
The Waterfall
The Waterfall is one of the most useful tools that can help you understand your website’s speed. The waterfall chart gives you insights on how long every resource on your website took to load and on every HTTP request.

When you examine this tab, you can better understand which resource needs to be optimized.
Consider this example: if your image file is taking a little longer to load, you can optimize your images using an image optimizer tool to reduce the size and improve loading time.
Additionally, if the test summary box says 25 requests, you will have 25 different waterfall entries, and it needs to load 25 different assets.
Every bar on the website displays how long each asset took and all the steps involved. The possible steps each asset goes through are DNS lookup, connecting, blocking, sending, waiting, and receiving.
Depending on this information, you can make assumptions about the workings of your website. Although the waterfall chart is the most technical aspect of the test section, it is one of the most helpful ones.
Timing
The timing tab is another crucial tab that gives you detailed insights into how and when your page loads. The timing tab makes it easier to visualize compared to the waterfall tab.
While most users think of page load time as a single metric, there are various definitions for when you can determine your page ‘fully-loaded’.
With this tab, you can investigate various performance metrics such as First Paint, DOM interactive, onload, TTFB, First Contentful Paint, and DOM loaded.
Additionally, the tab also gives you detailed information for each metric, which is exceptionally helpful. However, you won’t be able to get this report if you do not register for the free GTmetrix account.
Video
The video tab is another essential tab that enables you to understand how your site loads for your users. With the video tab’s help, you will be able to see the entire page loading process.
This enables you to understand which page is taking more loading time visually.
You can slow down the video speed to ¼ to quickly see how the content shifts. You can also see if there are glitches when the page loads.
To take the video recording of the process, all you need to do is register for the free GTmetrix account and enable the Create Video setting when running the test.
This feature is useful to optimize the performance of your website. Additionally, the video feature allows you to immediately catch various issues that won’t be possible if you do not visually see the process.
Moreover, GTmetrix also gives you the option to download the video.
History
As we mentioned previously, you need to test your site multiple times rather than relying on just one test. Therefore, the history tab comes in handy to see previous results so you can analyze how your site’s performance has changed over the tests.

The tests are stored for 30 days and deleted after that. For example, if you are making any changes to optimize your website’s performance, you can easily view it.
Additionally, you can see the history in a graphical representation. The history tab shows the YSlow score, PageSpeed score, size, change in page load times, and more.
Another excellent feature is that it lets you add notes. If you switch to a new host, you can add notes to GTmetrix to see how it has affected your website’s performance.
The history tab is essential to analyze the improvements your site has made over time.
