A company called Sellathon recently launched a product called ViewTracker, and they say on their Web site that ViewTracker "tells you ... in real-time ... exactly how each auction visitor found you, what words they searched for, what categories they browsed, how they sorted their search results... even where they live."
Up to now sellers have not been able to get in-depth visitor data on their auctions. Sellathon's solution should give eBay merchants the kind of detailed market intelligence they need to increase sales and improve results.
