Macy's Ranked No. 1 Online Retailer of 2012

Think tank L2 has released its annual Digital IQ Index, which ranks 76 specialty retail brands on factors including website, e-commerce experience, digital marketing, social media and mobile. This year, L2 says the real game changer in digital retail is mobile. According to the report, "82 percent of users report using their mobile devices in-store, leading to a showrooming effect, where users experience product in-store but purchase via mobile." L2 predicts m-commerce will grow at a rate of 30 percent to 40 percent a year compared to online and brick-and-mortar retail.
