"The Mercent eCommerce Performance Index reflects remarkable online retail sales performance this holiday shopping season," commented Mercent CEO Eric Best. "Year-over-year same-seller GMV across all Mercent-support channels increased 34%, and sales on Amazon and Google Product Search also grew by 75% and 37% respectively. We are confident growth this year continues to be driven by value-conscious consumers. However, this value-driven shopping trend is no longer a function of a soft economy, rather a permanent change in retail shopping behavior. With purchasing information and capabilities directly at their fingertips via browsers and mobile apps, consumers are armed with real-time data on pricing and product availability, promotions and offers, member discounts, and group-buying and local offers to evaluate every purchase. The implication for retailers is the requirement to fully engage customers online and on mobile devices in deliberate and increasingly sophisticated ways in order to effectively compete, survive and thrive."
