According to very respected research, it’s estimated that approximately a lot of people browse the Web via a mobile device. When those people view your site, are they seeing your site in the best possible format for their small screen? With the new Mobile Theme in Jetpack, you can be sure that they are.
Jetpack’s Mobile Theme displays your content in a clean, uncluttered interface, making it easy for mobile visitors to scan your site. We took special care to make the mobile theme as lightweight as possible to ensure quick navigation and fast loading times for those sometimes spotty mobile connections.
