The document summarizes mobile usage statistics from a financial publisher. It shows that in 2013, the majority (62.9%) of mobile users on the publisher's sites used Apple iPhones, followed by Android (30.1%) and Apple iPads (6.2%). Most mobile users were between the ages of 18-34. While mobile and tablet traffic accounted for over 15% of total traffic and clicks for the publisher, their revenue contribution was only 11.9% due to lower click-through and revenue per mille (RPM) rates compared to desktop. Users also spent less time on mobile and tablet sites than desktop.
