Spikes & Dips April 2016: State of E-commerce in the US

What is our Spikes & Dips Series?

Intelligence Node’s Spikes & Dips series tracks the retail price change of a basket of products spread across online retailers using our real-time retail analytics software. ‘Spikes & Dips’ covers the top 1000+ leading North American e-commerce retailers and is continuously monitored by proprietary market-monitoring algorithms. Intelligence Node’s algorithm processes approximately 750mn products daily and are taken from real-time, live data. All benchmark indexes are tracked in real-time, however, updates will be published in our monthly State of E-commerce newsletter.

The goal of our Spikes and Dips series is to put online retail price movements in the context of macroeconomic factors thus enabling retailers to understand how these macroeconomic factors influence their day-to-day retail pricing strategies.
