2013 promises to be the year of mobile marketing.

For the first time, brands and businesses are seeing mobile search outpace desktop search, and the ROI from mobile marketing efforts is higher than ever.

Indeed, mobile advertising is on track to pass $5 billion by 2015.

So what does this mean for content marketers? For one thing, it’s absolutely essential to stay tuned to consumer mobile behavior.

For example, a few key stats gleaned from the infographic below:

-There was a 300% increase in mobile open rates from October 2010 to October 2012
-Mobile doesn’t necessarily mean “on the go”; 51% of mobile users in the U.S. are at home on their phone, and 18% are at work
-Percentage of blog visits from a mobile or tablet went up 22% from December 2010 to November 2012
