Google announced via their Webmaster Central blog today that they have recently updated PageSpeed Insights with mobile-specific recommendations to help site owners make their page more mobile-friendly. Page Speed Insights measures the performance of a page for mobile devices and desktop devices. It fetches the url twice, once with a mobile user-agent, and once with a desktop-user agent.

The announcement states:

Poor usability can diminish the benefits of a fast page load. We know the average mobile page takes more than 7 seconds to load, and by using the PageSpeed Insights tool and following its speed recommendations, you can make your page load much faster.

Google suggests that if mobile users have to spend additional time after your site loads to pinch-zoom and scroll through the screen in order to read the text, then your fast-loading site isn’t really all that fast after all. Google’s new PageSpeed Insights’ user experience rules can help site owners identify and correct issues that could be impeding the overall usability of the site.

For more information about these rules, please visit Google’s help pages. To see how mobile-friendly Google considers your site to be, you can test your pages and the improvements you make using the PageSpeed Insights tool.
