According to Forrester Research, US online retail reached $175 billion in 2007 and is projected to grow to $335 billion by 2012. Business-to-consumer (B2C) eCommerce continues its double-digit year-over-year growth rate, in part because sales are shifting away from stores and in part because online shoppers are less sensitive to adverse economic conditions than the average US consumer. Despite the continued growth of the channel, online retailers face several challenges to growth: Online stores are broadly perceived as a second choice for shoppers, online retail is becoming increasingly seasonal, and online shoppers rarely admit to browsing, which can drive valuable incremental dollars during their Web shopping experiences.
