Google has announced a speed testing tool called Think With Google to help you measure your website’s speed and mobile-friendliness.
The site takes your URL and measures on a scale of 1-100 your mobile design and loading speed. It looks at things like CSS, HTML, scripts and images to see how long it takes for your website to load on both a desktop and mobile device.
There are three rating categories: Mobile Speed rating where Google says an average user leaves the site if it doesn’t load on mobile within three seconds, so if your site takes much longer than that, your lower will appear lower; Mobile Friendliness rating where Google says people are five times more likely to leave a mobile site that isn’t mobile-friendly; and Desktop Speed rating where Google says 9 out of 10 people say they use multiple screens for such tasks as booking a flight online or managing their personal finances.
On carrying out the test for Techloy.com we had this report:

The site tool also tells you what to fix in order to get a better rating on any poor scores, plus you can choose from a list of platforms that simplify site building.
