Comparison Shopping Engines (CSEs) are also called comparison shopping websites or price comparison websites. Let's take a look at the top comparison shopping engines, which drive most of the product sales and revenue through search engine listings and web ads.
What are Comparison Shopping Engines?Comparison Shopping Engines are websites that push the sales of e-tailers and other online sellers interested in getting a sales boost.
Comparison shopping engines list down products based on their price, and also lets the user filter them out based on features, shipping, and other options. CSEs list the products vertically, and hence, belong to the category of vertical search engines. To get listed, a seller must sign-up with them and then submit a desired product feed format. These websites can then automatically source and list data from these feeds into different listings.
It was launched as Froogle in 2002, and is now the most popular CSE around, driving maximum clicks and revenue to the e-tailers listed on it. Advertisers not only benefit from the huge traffic that it receives, but also get enrolled in Google AdWords―a PPC advertising program―and their products get more exposure when they show up in the search engine results page (SERP).

This was launched in 1999, and was the first CSE to include tax and shipping cost information, thus giving a shopper a complete idea about the final price.

Merchants like PriceGrabber, as they can set the CPC to as low as USD 0.01, and also get the added benefit of being listed on Yahoo Shopping.

Amazon Product Ads work on the PPC (pay-per-click) model. After signing up, merchants have to upload the information about their products via FTP, and then allocate the budget to be spent on ads. The ads show up on detail pages, search results, and even in the 'buy box' on Amazon.com, and thus provide more exposure to the items listed by the merchant on their own websites.
