How to Check Website Speed Manually

In the previous article, I have explained the importance of speed of your website. Shortly, I'll explain the best way to manually check your website speed.

The purpose of website speed acceleration is to make it easier for our website visitors to make an interaction. Thus, we need to perceive the concept of speed from their perspective. Here are the tips for testing the speed of a website manually.

1. Testing With Various Devices – Desktop, Cell Phones and Tablets

In general, most visitors access the internet using mobile phones. About 80% of visitors use a cell phone, while the rest use a desktop browser.

However, it might be different with your case. Therefore, it is advisable for every website owner to perform an analysis on their visitors to identify the characteristics of their visitors.

For most websites, it is very valueable using analytics tools such Google Analytics. As a result, we can evaluate and recognize the number of people using mobile phones and desktops.

2. Testing With Various Web Browsers

We can identify not only the devices but also the browser they used if you are using analytical systems such as Google Analytics and Facebook Tracking Pixel.

The most commonly used browsers are Google Chrome, Firefox, Safari, Edge, and Internet Explorer. Therefore, we need to test the speed of our site using all of these browsers to get more accurate results, as it the browser settings are different. We need to make sure our website are capable for all kind of browser instead of chrome user only.

3. Testing In Incognito / Privacy Mode and Cache Mode

We need to test in two situations too, which is the Incognito / Privacy mode and What is the Cache Mode?

Incognito / Privacy Mode – A situation where your visitors for the first time accessing your site with no information, data or cache is stored. Every internet browser usually has special settings for privacy mode, such as Incognito Mode by Google Chrome and Firefox Privacy Browser.

Cache Mode – A situation which your visitors already have information or cache stored in their browser data. This usually happens if a visitor has accessed your site before. In this case, the data such as pictures and website information normally will be stored in the visitor's browser.

The Difference Between Cache Mode and Privacy Mode – For the reason that the website is already stored in the browser,  there is no requirement for the visitors to get the data from the server. Hence, it will make the website easier and faster to access.

4. Measuring The Loading Period With Appropriate Techniques

There are several appropriate ways to measure the time. The easiest way is to count yourself in the head, how many seconds it takes. However, this technique may not be exactly the case.

Alternatively, you can use the stopwatch or mobile phone. You may need to try several times to get used to it. You also need to use both your hands. One hand to open the website, and the other hand to start the stopwatch.

5. Retrieve The Data Speed

Make sure you are not doing the test once. It is a good idea to do multiple trials and record the displayed time. You may press the stopwatch button starting from (the first time you saw something appear) until (when all content appeared and no longer loading).

Test Sample
Browser: Chrome
Device: Phone Cell
Internet: Umobile 4G

TestContents Start TimeContents End Time
11.5 seconds2.5 seconds
21.7 seconds2.3 seconds
32.1 seconds 2.8 seconds
Average1.77 seconds 2.53 seconds

As can be seen in the example above, three tests were performed, and the average was taken for reference. Information such as the best and the worst records should be recorded too.

6. Make An Analysis

Once you have all the data, you can analyze your test results. There, you can tell the satisfaction level of your site’s speed.

7. Run An Additional Test

Manual test helps you get the speed data right. But for the normal user, you may have trouble in identifying because due to the low speed of your site. Therefore, it's a good idea to use test techniques using Chrome Dev Tool, GTMertrix, and Pingrom.


Running a speed test manually usually will take some time. However, it is important for your business. Test result from tool aid such as Dev Tool and GTMetrix does not show the exact status of your users.

Your results on GTMetrix may be good, but your website users may not feel that way. Therefore, manual testing is necessary if you are taking seriously in providing the best service for your visitors.
