Top Website Performance & Speed Test Tools You Should be Using
Speed is a major component when it comes to your website optimization. Fast websites with modern web design will generally greatly contribute to the overall success of your online business.
With everyone being in a rush nowadays, all apps and tools also need to function as fast as possible. Your website needs to be optimized properly; otherwise, you may lose on traffic and conversions. And if your site is sluggish with low functionality, your online business could end before it even started. With that in mind, there are no alternatives that can help you go around website optimization – you just have to get on and deal with it. If you don’t have a fast-loading website, your visitors will most likely skip it, even if it’s full of great content.
Luckily, there are plenty of test tools that can help you with your website optimization. For this post, we will go over 12 of the best speed test tools on the market.

The Importance of Speed Testing a Website
Typically, your goal is a fast website. That’s why you need to know the current speed condition of that website. Here is where the speed test tools come into the scene. Testing your website is the first crucial step you have to take when aiming for an optimized website with better loading times. Speed testing will help you set a benchmark and measure all the changes you need to make to provide the best user experience (UX) in terms of speed. Overall, testing is the best starting point whenever you are about to work for improvements.
The ideal speed for your website is 1 second in the country where it’s being hosted. That minimum loading time feels like an instant. However, speed varies for several factors, such as marketing tools or other tracking software. With that, you can still aim for a loading time of 1.5 seconds, which is still quite acceptable.
When testing the loading speed of your website, consider several speed tests, and then averaging them out. That’s because results can vary from one test to another, mainly due to DNS caching, CDN caching, and WordPress caching.
Reasons Why Website Speed Matters
Website Speed is the First Thing People Experience
In life, first impressions are important. That’s the same when we talk about the web. Therefore, the first impression your site makes is crucial to your overall success. The first noticeable thing when you go on a website is how long it takes to load fully. Most viewers or customers make their quick judgment based on that first impression and decide whether they are interested in continuing browsing the website they have entered, or skip it and go to the next one. If you have done everything properly to quickly make your website load, you can be sure that you’re most likely making a great first impression. When it comes to traffic and conversions, user experience is of great importance.
Users consider fast and good-looking websites to be professional, and therefore – reliable. On the other hand, a slow website not only makes people think it’s unprofessional, but it also makes them feel unsafe, which is the main reason for them to close it as soon as possible. If you own an online shop, know that most online shoppers will not come back to your website if it loads slowly.
People Expect Fast Website Loading Times
The Internet demands quick websites, mainly because there’s a great competition that grows constantly.
Based on the feedback of 1,048 online shoppers that were surveyed, Forrester Consulting concluded the following key findings:
- 47% of consumers expect a web page to load in two seconds or less;
- 40% of consumers will wait no more than three seconds for a web page to render before abandoning the site;
- 52% of online shoppers state that quick page loading is important to their site loyalty;
- Shoppers become distracted if they have to wait for a page to load. 14% will begin shopping at another site, and 23% will stop shopping or walk away from their computer;
- Retail and travel sites that underperform lead to lost sales. 79% of online shoppers who experience a dissatisfying visit are less likely to buy from that site again. 64% would simply purchase from another online store.
Patience is something that’s not easy to find when it comes to people on the move. Everyone wants their information quickly.
We all want quick answers and immediate results. However, if an authority site like Google or Amazon is loading a bit slowly, people tend to have more patience because they know they are in the right place. That said, if you are still a small or medium-sized business, you don’t have that luxury, and you need to make sure your website is as fast as possible, right from the very beginning.
Website Speed is a Major Ranking Factor
Search engines like speed in general. Google’s mission is to improve the Internet in every way, and speed is among the most important factors. Here’s what the search engine said about speed and your Google rank back in 2010:
“While site speed is a new signal, it doesn’t carry as much weight as the relevance of a page. Currently, fewer than 1% of search queries are affected by the site speed signal. It basically means that the average websites won’t see much change. But, if your site is super slow, you will suffer.”
Keep in mind that Google will reduce the number of crawlers on your website if your loading time is below 2 seconds, which means that your newest content will need more time to get picked up for organic searches. That’s not good for you.
Better Speed Equals Better User Experience
We often mention user experience in our posts. It’s quite important if you aim for your website to be set apart from the competition. UX design is about creating an attractive yet simple environment for your visitors. There are 2 main factors to consider when it comes to positive user experience.
Basically, if someone is on your website, they are there for a specific reason. You want to give users what they want as quickly as possible, so the chance for them to come back is higher. On the other hand, people are likely to leave your site if they have to wait, and they will likely share their negative experiences with friends or on internet forums.
Faster Loading Times Lead to Greater Conversion Rates
If the sluggishness of a site drives people away, that naturally affects your sales. That has been tested multiple times. For example, Amazon’s test showed that they might lose roughly $1.5 billion a year if their website loaded just a second slower. And that’s an established online shop. Imagine what would happen with a small one.
How to Read Basic Speed Test Parameters
Before we start listing speed testing tools with their specifications, we will briefly explain the most important parameters you will often see when using those tools.
Something important to remember when it comes to your website URL – use the site’s primary web address (with the www at the beginning). People often skip the www part of a website’s URL, which can potentially add 1, even 2 seconds to the loading time. That’s because the website is actually loading its default version (with www).
This one is crucial. The “Test From” parameter stands for the location of the speed test. Most of the time, you would want to choose a country where you get the most traffic. You should also expect a bit slower loading times in places outside the country where your website’s server is located.
Load time is perhaps the most important metric. You should always try to get loading time under 1 second. However, we already mentioned that you could settle for up to 2 seconds. It’s still quick, just doesn’t feel as instant.
In this section, you will see the tested page’s total size. If a page is smaller, the loading speed should be quicker, and vice versa. Typically, a site with lots of images will be around 2mb, but it’s not unusual to see pages with even 15mb. Such pages would be very sluggish on a standard internet connection.
As with page size, lower requests are also better than higher. Websites are generally considered fast when they have between 50 and 100 requests. If you cross the 200 requests mark, your site will start to feel very slow. That’s especially noticeable on mobile devices because their CPU power is usually less than that of an average computer.
Website Speed Test and Analysis Tools
There are many website speed test and performance monitoring tools on the market, both paid and free, but we handpicked some of the best ones to consider. Each one of them has excellent features that distinguish them. You don’t need just to test your website with one tool. You can use multiple tools and run multiple tests to be thorough. However, one of the most important things for website speed optimization is to pick one tool to test your website, run analysis, and stick with it when you focus on improvements.
GTmetrix is a well-known speed testing tool and is one of the most frequently used ones on the Internet. GTmetrix is fairly easy to use by people that are not too familiar with technicalities.
GTmetrix uses results from Google PageSpeed Insights and YSlow to generate a score for your website and give you recommendations. The tool assigns a grade from A to F, with the generated reports being split into 5 sections:
- PageSpeed score
- YSlow score
- Waterfall chart
- Page Load Timings
- Report History
For more details on the last two sections and an overall understanding of how they work, go ahead and create a free GTmetrix account. Explore the tool, and you will see for yourself how helpful it can be. If you wish, you can also choose to purchase the GTmetrix Pro version. That goes, especially if your site is larger and more complex. Also, make sure to check out our in-depth tutorial section, where we dive into how to use the GTmetrix speed test tool.
Additionally, you can choose the browser you want to do your test with, Chrome or Firefox (desktop versions). You can also choose to make tests while comparing website performance according to different connection types (dial-up vs. cable). This way, you will get more thorough information about your page load times, which is always helpful. You will also find the server select option particularly useful since you can test the website’s speed globally on behalf of your visitors.
Keep in mind that GTmetrix is widely used, and many of the tool’s servers are often overloaded. That can make the speed tests seem slower than they normally should be.
Pingdom, like GTmetrix, is one of the most well-known speed test tools on the Internet. A Swedish-based company, Pingdom offers several different services, but it’s most famous for its free speed testing tool. With that said, you should consider that the performance grade doesn’t really correlate with performance. However, Pingdom is still a great speed testing tool to use.
Pingdom’s popularity is because it’s straightforward to use. Since not everyone is a web performance or web optimization expert, such tools can be overwhelming.
When using Pingdom, you will need to enter your site’s web address (URL), as well as the location you want the test to be done from. As always, it’s best to choose the location closest to where your site is being hosted.
Pingdom’s speed test reports are initially split into four sections: performance grade, total load time, total page size, and the waterfall chart.
You can find more detailed information below those four sections, meaning you get a nice overview of what’s important when you aim to improve page performance. You can easily compare your website’s CDN asset size with one of your domains and compare the number of requests by domain and the type of content on your website that had the most requests.
Google PageSpeed Insights
Google PageSpeed Insights will not provide you with lots of data that will help you optimize your website loading times. However, there are still good reasons why you should check out this tool by Google.
Google’s results matter because Google is actually the one creating the search rankings that you aim for. Therefore, when Google finds issues in website performance, you should take them seriously.
Like other tools listed in this post, PageSpeed Insights is also an easy-to-use one. It requires only your website URL (web address), and after your inputs, it quickly generates the performance for both the mobile and the desktop version of your website.
PageSpeed Insights grades your website on a scale from 1 to 100. The higher the number—the better your site has been optimized. A good benchmark is a score of 85, meaning that your website is performing quite well. Some example recommendations that the tool gives you are advice on image optimization and minifying CSS.
The PageSpeed Insights mobile report has an additional category called “User Experience.” It’s included in your score, recommending an optimal size of tap targets (buttons and links), viewport configuration, and eligible font sizes.
This speed testing tool is well suited and most used by small and middle-range businesses and independent website owners that look for a straightforward and easy way to keep up with optimal website performance.
In reality, the PageSpeed Insights score doesn’t really have too much to do with actual speed. While the tool is still pretty useful, you should be aware that it only measures speed partially.
A large part of the generated score comes from the comparison made by putting your site against a technical checklist. With that, the tool often doesn’t consider specific practical limitations of the website coding and design.

А Few Examples from FastComet
As a daily practice, we are happy to help our clients handle their optimization needs and analyze the collected data from different tools. The two most used tools our agents utilize are GTMetrix and Google PageSpeed. We use those in particular because of their comprehensive nature. While you can always consider them as suggestions for running website speed tests on your own, it’s entirely up to you to choose which one of the listed tools in this post would fit your needs best.
The examples below share a few real-life scenarios in using GTMetrix and Google PageSpeed.
Ex.1 PageSpeed uses Google’s ranking algorithm and shows the most basic information and easily grasped details on editing different website fragments for better results. The following chat scenario shows a FastComet agent analyzing the GTMetrix results for further optimizing the website speed based on the report.
Martin B.: Okay, here you can see the results : > https://gtmetrix.com/reports/… The main thing that is slowing down the loading is the homepage – 38.5 MB – this is a lot. As you can see, the PageSpeed score is 45%, which could be greatly optimized.
Client: So it’s the images only?
Martin B.: It’s mainly from the homepage, yes – but as you can see there are other things, like fonts, for example.
Ex.2 Additionally, FastComet’s Senior Technical Team offers expert help in optimizing some of the most widely used applications. The following chat case shows easy to follow steps on reaching the proper Department for this type of assistance.
Nicola R.: Here’s the result from your website’s performance test: https://gtmetrix.com/reports/… You can refer to this article when optimizing the low-performing elements you see displayed under PageSpeed and YSlow: https://www.fastcomet.com.tutorials/gtmetrix Since it is a WordPress website, we offer additional optimization, performed by our Adcanced Technical Support Team. You can do that over a ticket.
Nicola R.: If you’re interested, you can submit your ticket under “Script Installation,” via this link: https://my.fastcomet.com/submitticket.php Simply provide my colleagues with your WordPress login information on the ticket and they will update you within 15 minutes.
Ex.3 The YSlow score is using a Yahoo! algorithm for assessing the performance of a website. It can be considered as a complementary insight into the PageSpeed section. Below is another live example of a FastComet chat agent interpreting the GTMetrix report and giving suggestions based on the YSlow tab results.
Nick D.: As for your website > https://gtmetrix.com/reports/… There are some steps you can take to further optimize it. You can check them in the YSlow tab. The initial request to the servers comes between 300-400ms. It’s recommended to Reduce DNS Lookups, Avoid URL Redirects, and Make Fewer HTTP Requests.
Nick D.: You can show the report and the YSlow tab to your developer.
Ex.4 One of the most useful GTMetrix charts offers a detailed report on how fast the website resources are being loaded. Whether you use it to check if the HTTP request is successful, searching for the file size, or even reading the headers, it is a powerful tool to bring online to investigate which parts of the website can be optimized. The FastComet agent on the following chat instance uses the Waterfall section to find the culprit for a slow loading website and achieve better results.
Alexander Z.: Thank you for your patience!
Alexander Z.: I’ve tested your website, and then I have repaired and optimized its database. I have also added a few rules in the .htaccess file and I was able to improve the loading speed.
Alexander Z.: Also, after checking the Waterfall tab, I see that the website is actually loading from Cloudflare. You can confirm that by following the screenshot > http://prntscr.com/…
Alexander Z.: You can see that the “cf-cache-status” is HIT, which means that it’s loading properly through Cloudflare.
Ex.5 That same chart can also indicate the direct server response when loading your website, which clearly shows if the server performance is appropriate or should handing the resources on the actual website that needs to be corrected.
Martin B.: Thank you! Allow me a moment to run a test on the website.
Martin B.: Thank you for your patience! From what I can see the results are perfect, as you can see from this link: https://gtmetrix.com/reports/… The website is very well optimized. There is no reason for it to be slow – might be because of the internet connection. As you can see in the Waterfall section, the server response time is 500 ms, which is great.
Ex.6 A good alternative to be used for comparison is the official Google PageSpeed. It is definitely a useful tool for developers, webmasters, and all types of site owners. The following chat excerpt will demonstrate the result analysis of a client’s website.
Client: but I want you to try in Google PageSpeed
Dimitar L.: Here is the Google PageSpeed test: https://developers.google.com/speed/pagespeed/insights/url=…
Client: Because it’s also important to improve the speed on mobile.
Client: Yes, 62% is not good on mobile.
Dimitar L.: I see that your website is already optimized on your end and that you are using Cloudflare CDN.
Dimitar L.: As you can see in the Google PageSpeed report, you have some recommended things that can be done in order to further optimize the speed of your website.
A well-optimized website is crucial for the best possible experience users would get when interacting with it. As a website owner, speed is one of the most important things you need to have in mind. That’s why one of the first steps to take is making a speed test for your site.
SEO is important, and a quick loading website is better for SEO. Even that alone should be a good reason to keep your website optimized. A speedy website will get you not only a better ranking but also extra traffic and a better conversion rate.
