AERS has launched Terapeak 5.0, a subscription-based market research service for the eBay platform. Terapeak allows eBay sellers to research item pricing information (average pricing, sell-through rates, and more); the best keywords and categories to use; how to determine when customers are shopping; and two years' worth of category trends to track individual item seasonality. The new version includes information on what shoppers are searching for on the eBay platform and what products and titles are experiencing the most sales activity. Version 5.0 also has an easy-to-use interface that is welcoming to new users and existing subscribers.
