ChannelAdvisor (ECOM) clients saw a 23% Y/Y increase in their Amazon (AMZN) same-store sales in February. That's up from January's 14% clip, albeit down from the growth seen over much of 2013. ChannelAdvisor thinks improving weather contributed to the M/M growth pickup.
Clients saw a 15% EBAY same-store sales increase, up from 12.7% in January. Auctions fell 8.5% Y/Y, but fixed-price and Motors sales respectively rose 15.5% and 22.3%.
Search ad-driven same-store sales, dominated by traffic from Google (GOOG) AdWords placements, rose only 4.3%, down from January's 10.3%. Clicks fell 9% and cost per click (pressured by lower smartphone ad prices) 7%, while click rates rose 4%.
On the other hand, same-store sales driven by Google's increasingly popular product listing ads (PLAs) rose 48% Y/Y. That figure is down from January's 62.8%, but it's worth noting PLAs were only launched in late 2012. Average order value fell 8%, but click rates rose 17%.
