The 10 best free tools to test website speed

Spread the love

In the mobile age, it is imperative to know the 10 best free tools to test website speed.

This will ensure a pleasant browsing experience for users, without having to wait too long for a page to load.

You see it for yourself every time you do an online search: you want immediate answers otherwise you get bored and leave the site on duty….

Myself when I search for something on the web and find a slow site it makes me nervous and consequently I look elsewhere …

If you have recently approached the world of SEO, don’t worry …

… Although the speed factor is essential for optimizing a website on search engines, it is easy to check its performance!

But how?

Take 5 minutes and read the article! 😉


Some data on the user experience

According to some statistics, more than 50% of visitors leave a site that takes more than 3 seconds to load from a mobile device.

For this it is essential to know these tools, which I will list shortly, to test the speed of your website.

Keep in mind that in these 10 you can choose both the simplest ones and those with more advanced functions.


1. GTmetrix


A great tool for easily determining your website performance is GTmetrix.

It allows you to quickly obtain fairly complete information on the technical state of the site.

More importantly, you can see the order and time taken, in which assets are loaded on each page.

This way you will easily understand which elements you need to improve.

It will only take you a few minutes to get an idea of ​​the loading time, the data size of a page, resized images, etc.

Technically GTmetrix is ​​composed of two tools: which will elaborate a score from 0 to 100:

  1. Google Page Speed ​​Insights
  2. YSlow Yahoo.

The first is calculated using the Google Page Speed ​​algorithm and the second using Yahoo’s YSlow which takes into account, in addition to other factors, the number of HTTP requests made and the use (or non-use) of a CDN. (Content Delivery Network)



A CDN is a geographically distributed server system that makes content accessible more quickly by users around the world.

In other words, it allows you to load Internet content in moments, including videos, images, style sheets, HTML pages, javascript files.


You can also see if there are any anomalies via warning messages, which will be displayed on the screen.


How to interpret the results in Gtmetrix

Keep in mind that not all of them will be easy for a beginner to interpret and in this case, you will need some time to understand them.

However, each error is “clickable” and consequently, you will be explained more precisely what it consists of.

Based on the anomaly that presents itself to you, you can also write it on Google so that you can understand how to fix it.

Remember, it is not necessary to go crazy to correct everything perfectly, in the end, it is enough that the 2 scores that appear to you are green, which means that your site is performing.



As you can see in the image you will find these parameters:

  • Page loading time.
  • Total page size in KB.
  • Requests: Contains the number of resources, HTTP requests present in HTML pages.

You have to pay attention to the numerous resources within your site:

  • Images
  • Javascript
  • HTML
  • CSS

If there are too many of these elements, the pages will take longer to load.

Therefore, it is likely that some errors that you will find in the GTmetrix scan are due to these.

To correct these hitches, which slow down the site, the simplest solution can be, for example, to install a plugin to optimize images, CSS codes, JavaScript, etc.

Remember that site theme also affects loading speed and SEO score.


A personal opinion on the free version of the tool

In my opinion, this plan is more than enough to test your site’s performance.

You also have the option to access other options if you create an account.

For example, you can analyze your site URL from the location you want.

Also, you can choose which search engine to use.


GTmetrix is ​​also suitable for beginners

The use is very simple, enter the URL of your site and in a few seconds, you will see all the performance scores.

GTmetrix is ​​very popular even among beginners I used it too, as the first tool to check the efficiency of my blog.

Other functions of the instrument


  • Next, we can review the scans we’ve already done. This can come in handy to see if we have been able to improve website performance over time.
  • You can upgrade to the paid version (PRO), to set the analysis every hour. (You must not)
  • You also have the option to receive an email containing the various factors that influence the scores obtained with GTmetrix.
  • It is also possible to analyze the performance of the site from Android
  • Videos, containing the recordings of those elements that slow down the loading speed of the Blog.



As you can see from the image, here you will find all the tips to improve the loading speed.


You can investigate every single detail, so you know for sure what you need to replace or resize, for example, it often happens that the problems that arise are uncompressed images.


2. LightHouse and PageSpeed ​​Insight


This is certainly another great tool among the best known and most useful for site owners to test their performance.

Again, don’t get obsessed with the test score, but try to focus on the platform’s recommendations for improving loading speed.

To use Google PageSpeed ​​Insights you have to enter the URL of the site or a related page in the appropriate bar and then start the crawl.

Next, Google will give you a score from 1 to 100 based on various performance optimization factors.


In addition, you will also find some tips that will make you understand how to improve in those “poorer” areas to get a higher PageSpeed ​​Insights score.


PageSpeed ​​Insights scores are calculated through Lighthouse since 2018.

The latter is an automated open-source tool from Google that will be of great help in improving the overall quality of your web pages.

Through Lighthouse various factors that affect the performance of a website, progressive web applications, and more are analyzed …

Progressive Web App What are they?

It’s a site template that gives people a better experience by making sure they’re using a quality app.

Google in this case gives you results related to loading times and other factors, such as splash screens.


The combination of Lighthouse Pagespeed Insights is the result of a platform that more effectively processes data and various metrics to measure the performance of web pages.


Some truths, you need to know about the Google PageSpeed ​​Insights Score

As I said at the beginning of this article, you don’t have to put too much emphasis on getting a perfect score, but rather follow the recommendations that will appear at the end of the scan.

The key factor is being able to identify the problematic points of your site so that you can optimize it by reducing loading times.

Many aspiring webmasters know that PageSpeed ​​Insights is run by Google, the largest search engine in the world and they think the score may have some effect on the ranking of the search engine results page. (SERP)

In reality, Google takes into account the speed factor and consequently, if you get a high score on PageSpeed ​​Insights it could facilitate the ranking…

However, that’s not all …


…because if you have a super-fast blog, but with poor content, Google will never position you high in the rankings….

Speed ​​is just one of the many factors that search engines take into consideration.



Once you enter the URL in this tool, you will immediately receive a detailed evaluation on the following aspects (for both mobile and desktop devices):

  • Performance
  • Accessibility
  • SEO
  • Best practices
  • Progressive web

When PageSpeed ​​analyzes a page, several sections and performance indicators are returned:

  • Field data: This is data based on the real experience of users who have used Chrome in the last 30 days. They include First Contentful Paint and First Input Delay. This is a historical report on the performance of a given URL that can be analyzed by different users in the real world on a variety of devices.
  • Lab Data: based on a Lighthouse analysis, (an open-source technology from Google) carried out through scientific metrics, on a mobile device and the network.


  • Opportunities: These are important tips on performance metrics that could improve the load time of the analyzed web page.
  • Diagnostics: it is a section where you can take advantage of valuable advice on which best practices for web developers to adopt …


3. Pingdom


Pingdom is another great tool for evaluating loading speed factors via a score between 0 and 100.

You can use the free version where a test will be performed on your website, based on 7 criteria.

This tool also stores all the tests you have done previously, so you will realize the improvements made over time.

Pingdom is very simple to use, ideal even for beginners.

When you analyze a site’s data via the tool, it generates a performance rating, total load time, overall page size, and number of HTTPS requests


PINGDOM: WHAT IT’S GOOD FOR & WHEN TO USE ITSOURCE: https://reviews.financesonline.com/p/pingdom/


An example of scanning with Pingdom

As you can see in the example below, they are visible:

  • Scores
  • Size of the page
  • The overall loading time
  • Several HTTP requests: greatly affect the loading time; so the more files there are on your site, the more HTTP requests will be needed to navigate.


Note that all scores are based on Google PageSpeed ​​Insight rules.

Therefore, if you manage to improve these factors, your overall loading times will decrease accordingly.


Slow loading affects the user experience and this could lead to very high bounce rates.




To achieve this you must first have a good hosting service, otherwise, all your efforts will be in vain.

4. WebPageTest


This is an open-source project developed in recent years by Google that allows you to perform a speed test of the site by selecting some parameters including:

  • The server to test: For example for a blog with predominantly German readers, this means that you should choose a server in Germany.
  • Browsers including Chrome and Internet Explorer: I recommend that you choose the browser your audience uses most often.
  • Different countries around the world
  • Advanced test settings: for example, it is possible to define that some values ​​should be output, or that the measurements should stop automatically after a certain time.


Final thoughts on this tool

With WebPageTest you can perform simple or advanced tests which include several test repetitions, blocking of content such as javascript, video upload, etc…

This tool uses a score ranging from the letter A through the letter F and the colors belonging to each.

Green indicates a good degree of optimization, orange indicates poor optimization potential, and red indicates an urgent need for action.


You will get the speed test results in great detail, which you can dig deeper into to optimize those factors that slow down your website.

WebPageTest provides much more extensive test results than GTmetrix.

Remember I told you in the beginning that I would show you tools with more advanced features?

Well, WebPageTest is one of them because it allows you to reliably determine the absolute and perceived loading time of your site.


WebPageTest belongs to the category of the best and most complete free tools to measure the loading time of a page.

In my opinion, it provides a lot of data, but also quite complex to interpret, but if you know how to understand and analyze it in the right way you get excellent optimization results.


5. Google tests my site


It is a free tool provided by Google that evaluates the speed of a website from mobile devices and provides recommendations for improving the browsing experience.
