Comparison Shopping Engines (AKA Price comparison sites) have been around for long time and they started in the US back in the late "90s. Although they do generate a lot of traffic and sales they still tend to be neglected by e-commerce websites!Below we have listed 13 comparison shopping engines that every eCommerce website should (at least) give a try. Google Merchant is actually free to join and very easy to set up. The great advantage is that you get free traffic but also have you products feartured on the top of the search page results. For the other price comparison sites the cost varies and it really depends on the category. Usually the charges start from about £0.05 and it could go about to a £1. The main challenge for the price comparison sites is to actually set up a product feed that will list all your products. Unfortunately most of the sites have their own requirements which make it a time consuming exercise. Currently there are a few companies offering a managed feed service where you provide them with a feed and they adapt it for each site.Our advice on price comparison sites is to start with Google Base as a test and a one more paid one. Test it for a few weeks in order to see the results and then do a full launch. Unfortunately a lot of companies still don't fully utilise this channel.
