Mobile and social channels may be the key drivers of e-commerce growth this year, according to Monetate. The firm notes that mobile commerce, in particular, experienced a period of healthy growth and activity during the 2014 holiday season. During this time, mobile purchases increased by 45% over what they had been during the time period of 2013. Approximately 16% of all e-commerce traffic came from mobile devices as well, making mobile a valuable channel for the larger digital commerce space. Monetate notes that mobile experiences are improving, which is making it more likely for consumers to participate in mobile payments in some way.
