Google launched a new tool today called “Test My Site” at testmysite.thinkwithgoogle.com. The tool helps you find out how well your site works across mobile and desktop devices, but its primary purpose is to make the mobile web experience faster.

The new tool is part of the ‘think with Google‘ website that Google uses to announce studies and trends aimed in industry and to help webmasters and businesses make decisions. Google’s describes the site as a take on fresh marketing and a look at what’s next. It’s the place to go to find insights, trends and research in digital media and marketing. Google describes it as creative inspiration, industry intelligence and best practices for marketing leaders.

The new site testing tool provides 3 categories of measurement, MOBILE FRIENDLINESS, MOBILE SPEED and DESKTOP SPEED. Each of these areas receive a score of 1-100 and a link to view ways to improve. Here is an example from the Drudge Report, a site known not to be mobile friendly:

Here’s what Google says your scores say about your site

• Mobile-friendliness: This is the quality of the experience customers have when they’re browsing your site on their phones. To be mobile-friendly, your site should have tappable buttons, be easy to navigate from a small screen, and have the most important information up front and center.
• Mobile speed: This is how long it takes your site to load on mobile devices. If customers are kept waiting for too long, they’ll move on to the next site.
• Desktop speed: This is how long it takes your site to load on desktop computers. It’s not just the strength of your customers’ web connection that determines speed, but also the elements of your website.
