The speed of testing services appears to be a new thing for dabbing companies in their spare time – just weeks after Netflix started Fast.com, Google has announced its own tool to help you measure your site’s speed and mobile friendliness.

The site takes your URL and measures on a scale of 1-100 your mobile design and download speed. It looks at things like CSS, HTML, scripts and images to see how long it takes for your site to load on your desktop and mobile device.

If you need help though, Google links to a handful of site builders it obviously endorses to help you make your site mobile friendly and fast, including services like Wix, Duda, and Weebly. Great ouch for Squarespace and WordPress.
