PageSpeed and Usability Recommendations
The Web is becoming increasingly mobile and developers and webmasters need to be at their digital best to ensure an optimal user experience. To provide some support, Google recently announced that it has added more mobile usability recommendations in its PageSpeed Insights tool.
What PageSpeed Insights new User Experience rules provide are insights into issues that may be negatively impacting mobile usability. For example, your mobile site may be lightning fast (loading quickly), but if users are forced to spend an excessive amount of time scrolling or using the "pinch-zoom" functionality of most modern smartphones, an optimal experience isn't being provided. Google's PageSpeed Insights tool not only identifies the barriers, but also provides recommendations for creating a more usable experience for mobile visitors.
For example, webmasters will be able to determine if they successfully configured the viewport, make sure page content fits the width of that viewport, whether legible font sizes are being used, if tag targets are sized appropriately (see below for an example), and ensuring that the mobile sites doesn't rely - at least not excessively - on plugins to operate.
