Performance Matters!

Statistics show that nearly half of all web users have encountered slow page load times or worse, a website that crashes their browser. And over 53% of mobile users aborted websites after 3 seconds if they fail to load. Consumers want a speedy and error free experience. Giving the viewer anything less and you’ll risk them moving on to your competitors.

Website Speed

How does your site stack up?

Not all devices handle data the exact same way. Using the History of Performance you can compare metrics by speed, time and requests between different device viewports.

Having the ability to look at the page from different scan dates and device viewports will aid you in determining if the changes you have made are doing well (or not so well).

Site Stack Up

Analyze data on any viewport

Site loading speeds can vary greatly across device types. One of the biggest causes of this are high-resolution images. While these types of files might be perfect for desktop users who’ll have access to faster downloading speeds, these data-munching images are not so ideal for mobile users.

Review how your images load across devices and determine if any viewports would benefits from smaller lightweight alternatives. You can even compare multiple viewports at the same time, providing an even larger overview of your site!

Customizable Viewports

There are several default viewports to start off with. These come from a few of the most used devices such as the iPhone, iPad and Nexus. But not all websites are the same dimensions. With customizable settings, you can easily adjust them to fit your website needs.

The ability to customize viewports you are interested in is paramount, which is why we included the option to edit them.
