The Simple Configuration interface is correspondingly simple. You can choose whether to use a Desktop or Mobile configuration, using 3G, 4G, or Cable. By default, the site chooses a 4G Mobile configuration, testing from Virginia, USA. You can also include a repeat view of the site, and run a Lighthouse audit, but that’s where your options stop. For a simple test though, this is still a great starting point.
And not only can you run a Site Performace Test, you can also choose just to run one of the other tests WebPageTest offers, like Core Web Vitals, Lighthouse, Visual Comparison or Traceroute. By default, it runs a Site Performace test which includes the Core Web Vitals anyway.
There are simply too many options in the Advanced Testing section to cover, as this is designed to be a powerful tool for developers. But there are choices here not available in the Simple Testing section that can be very useful, even to beginners.
To start with, there are a huge number of Test Locations to choose from, and in the default location, also a huge variety of devices to use. Virginia is the default location, and with that location, you can choose from a large number of browsers and browser dimensions, which to run your test. If you prefer, you can even select your testing location from a map.
The diversity of testing options on offer make this a very powerful tool for developers. There is the ability to run up to 9 consecutive tests, and you can show results for the first view only or also the repeat views, and you can capturing video of the page load as well. Going into the other tabs would only be useful for developers, but there are a huge range of options to customize your tests as much as you want.
