PriceGrabber is one of the top-tier Comparison Shopping Engines, they command 5 million unique monthly visitors (it jumps up to about 8 million during the holiday season). Out of all the different shopping engines, I have seen the best ROI from PriceGrabber. Here are some ideas on how to boost your performance on PriceGrabber.

Product Categorization
The hardest part about syndicating products to all the Comparison Shopping Engines (CSE), is categorizing products properly according to each individual taxonomy. When you invest the extra time and categorize everything correctly, you will definitely see a boost in your click-through rate and conversions. If you have a large data feed you should consider mapping your categories to the corresponding category on PriceGrabber.
Merchant Logos
When a customer comes to a page comparing product prices from 10 sellers, the merchant logo option will help your listing stick out. Logos are not free though, PriceGrabber charges an additional $0.10 per click logo listings. However, like everything else in life: you get what you pay for. Logo listings have historically show higher conversion rates than products listed without them.
Merchant Reviews
It is imperative to maintain a positive rating on PriceGrabber as well as all CSEs. Not all customers shop by price only, sometimes a customer will pay a few dollars more to purchase from someone with a higher rating than you. The best idea is to push your customers to review their purchase.
Featured Sellers
PriceGrabber is one of the few CSEs that offer the ability to have your products listed with a Featured Seller status. You will need to talk to your PriceGrabber account representative to get pricing information and sign up for it. In the categories that I have tried Featured Seller product listings I have seen a boost in conversions, although I’m not sure what kind of performance it would have in a heavily saturated category such as digital cameras and iPods.
