Web Performance Analysis with Google’s “Test My Site”

Does your website load in under 3 seconds on a phone, tablet or PC? If your site does not load in 3 seconds, then you have immediately lost 50% of your customers. Performance is critical to the success of your website, and Google is stepping up and providing you a great tool to test your site: https://testmysite.withgoogle.com

Using Google’s Test My Site

The world is going mobile first. Google has a tool you can use to help test your website. The device is called Test My Site and has the friendly URL of https://testmysite.withgoogle.com

The test is easy to do. Enter your web address and select “Test Now.” The test takes about 60 seconds to run. When the test is complete, you have a report that you can use to drive direction to improve your site’s performance. The goal, as always, is to stop people from leaving your site.

Analyzing the Test My Site report

The report you receive back from Google highlights three main sections:

  • Mobile Friendliness
  • Mobile Speed
  • Desktop Speed

What is interesting is that the focus of the report is not “how does your website respond on a mobile device” but “how does your app react in a Mobile First world” where Mobile is the primary device by there are many secondary devices, too.

As you might expect, the Mobile Friendliness section looks to see how your site behaves with responsive design. There should be no excuse for having a site that is not responsive. Everyone should get a 99/100.

The second two sections focus on performance. How fast does your site load? Google will provide you details on the areas you need to tighten up such as image compression, JavaScript compression, re-writing how you use CSS and leveraging modern Web Server tools such as an HTTP/2. The goal is simple: speed up your site.

As a frame of reference, the first time I ran the tool I was running my site with no compression tools and my result was a meager 24/100 for speed. I added an image compression tool and dramatically increased the performance of the site.

The goal is for you to speed up your website. Run the test and analyze the results.
