A number of people have asked me about the CPC rates on the shopping comparison engines. While the chart below isn’t perfect (please let me know if you identify a mistake), it will give you some idea of the price floors on Shopping.com, Shopzilla, NexTag, and Yahoo! Product Submit (YPS). Merchants can use this data to figure out unique opportunities. Analysts will most likely just be interested in tracking the minimum per click rate over time.
Zeros indicate no match for that particular category (for instance, SDC has a category for Vacuums and NexTag doesn’t. I’m not saying that NexTag doesn’t sell Vacuums, they just put it in a broader category that I couldn’t immediately identify). The bottom row is the average CPC rate.
Remember, these are just price floors. As with Google Adwords and Yahoo! Search Marketing, merchants on many shopping comparison engines are allowed to bid up their prices for featured placement.
