Google has updated PageSpeed Insights and added additional recommendations for mobile usability.... Making your site more mobile-friendly with PageSpeed Insights Monday, May 19, 2014
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.
Key recommendations are to...
- configure the viewport
- size your content to the viewport
- use legible font sizes
- make touchscreen tap targets large enough to use
- and avoid plug -ins.
