GTmetrix is a website performance analytics tool that you can use to check your website's speed and performance. In this article, we will go through all of the sections of GTmetrix to get a better understanding of this tool.

Before you start

It is highly recommended to create a GTmetrix account as that allows you to choose the test location and device (and enable many more options).

Why is it important? Because the physical distance between the server and the visitor is important for the speed, so if for example your server and your visitors are located in Europe, you will get much more accurate data if you run the test from the UK rather than from Canada (default location).

Having an account will also allow you to avoid the queue 😉
