|About: ChannelAdvisor Corp (ECOM)|By:, SA News Editor

ChannelAdvisor (ECOM) clients saw their Amazon (AMZN) same-store sales rise 26.5% Y/Y in September. That's better than August's 24% and July's 24.9%, albeit still down from the 30%+ rates recorded earlier this year.

EBAY same-store sales growth, on the other hand, fell to 17.4% from August's 20.4% and July's 17.7%. Fixed-price sales +19.4% vs. +20.2% in August, auctions +8.4% vs. +7.8%, Motors +14.4% vs. +18.5%.

Google's (GOOG) numbers improved: search ad-driven same-store sales +1.8% vs. +0.2% in August, sales driven by shopping engines (such as Google Shopping) +10.6% vs. +7.7%.

However, the search ad-driven sales growth was fueled almost entirely by a 17% Y/Y increase in average order value to $113.72. Ad clicks fell 6% and orders 5%, and ad prices (CPC) slipped 7% to $0.50. ChannelAdvisor speculates consumers shopping for cheaper items are relying less on search in favor of Google Shopping.

For reference, comScore estimated total U.S. e-commerce sales growth (exc. travel) was 16% in Q2.
