Google PageSpeed is the definitive tool to analyze mobile, laptop, and desktop web page download speeds. This free Google service gives you a quick view of how your site looks on a smartphone and non-mobile screens.
In our cloud computing, social media, and mobilized age, content may be king. But loading blog and website pages quickly are Queen. Viewers, we’re told, leave slow sites within 3-4 seconds if displays aren’t mobile-friendly. Worse yet, they’ll probably not return. 
Web page speed is one of the most critical factors for business success as technology improves. Mobile Web page performance is even more important since 60%+ users use mobile phones to visit websites.
Facebook and other social network site mobile visitor rates are even higher.
