What are Comparison Shopping Engines?

Comparison shopping engines collect product information, including pricing, from participating retailers and then display that collective information on a single results page in response to a shopper's search query. In this way, shoppers can compare each retailer's price, shipping options, and service on a single page and choose the merchant that offers the best overall value.

Example: Lets say I want to buy a Rubik's Cube and want to see what my options are. I go to Google Shopping (one of the most popular CSE's around) and do a search. Here's what comes up: 

For ecommerce merchants, comparison shopping engines are an opportunity to put your products in front of very interested buyers. These are not people perusing a virtual storefront like a window shopper at the mall, rather CSE users typically have already made the decision to buy and are simply looking for the best deal.

10 Popular Comparison Shopping Engines 

1. Google Shopping

Google Shopping is probably the largest and best know comparison shopping engine. Products submitted to Google Shopping will also be displayed on standard Google search results and are integrated with Google's pay-per-click platform, Adwords.

2. Nextag

Nextag has been in operation since 1999 and has as many as 30 million visitors each month. Nextag is consistently a top performer for traffic and conversions on CPC Strategy's quarterly review of leading CSE's. You can list products, event tickets, real estate, and even travel bookings. 

3. PriceGrabber

In addition to presenting products on its site, PriceGrabber has a market research tool, Market Report, that allows retailers to track consumer purchase and product pricing trends. When you list your products on PriceGrabber, you'll also be listed on Yahoo Shopping which is a nice added bonus.

4. Shopping.com

Shopping.com is part of eBay's family of companies and is another great channel for merchants to put their products in front of perspective buyers. Shopping.com also partners with The Find, another CSE on this list.

5. Shopzilla

With about 40 million month visitors and a pedigree dating back to 1996, Shopzilla is one of the best choices for ecommerce merchants looking for some extra sales. This comparison shopping engine has an impressive 100+ million products listed. 

6. Become

Become is another leader in the CSE space, allowing thrifty shoppers to compare prices, read or write product reviews, and simply search for the best possible online shopping deals.

7. Bing Shopping (Free)

Bing Shopping offers free product listings that appear directly on Bing search results pages. Bing Shopping has earned a lot of consumer praise for doing an excellent job of providing consumer friendly results. The service does not accept new merchant feeds during high-traffic shopping seasons, so get started early with Bing in 2013.

8. Pronto

With about 70 million product listings sorted into various retail verticals and millions of visitors monthly, Pronto certainly merits consideration for any retailer's 2013 CSE campaigns.

9. The Find (Free)

In addition to showing product and price comparisons, The Find can help shoppers discover new products with personalized results.

10. Amazon Product Ads

Amazon isn't technically a comparison shopping engine, but they work in a similar fashion. When you register for Product Ads you can upload your products manually or via FTP. Amazon will then create ads for your products using the information provided in your product file. When you set your budget, your ads will go live and you'll pay-per-click.

The Cost of Comparison Shopping Engines 

Although some of the CSE's are free, most are going to charge you per click-through or per action. With pay-per-click, sellers pay a set fee or bid each time that a potential customer clicks on that merchant's link. Here's an example using Amazon:

In a pay-per-action model, retailers will pay a percentage of the value of a sale made as a result of being listed on the CSE. No one pricing model is best, so choose which works best for you. 

How to get Products Listed in Comparison Shopping Engines

Most CSE's require retailers to submit a formatted product feed. This feed must meet a CSE-defined specification and should be updated frequently. The CSE uses scripts to parse and ingest the data from the feed, displaying the included information on results pages as appropriate.

Shopify merchants have several apps available that make submitting product feeds to CSE's easier and in some cases, automatic. For example, RetailTower is a free Shopify app that can help prepare feeds for many of the top CSE's listed here. Regardless of how a feed is created, smart merchants will work to optimize descriptions and prices get the most sales possible.

    Many times I got confused about to consider many e-commerce website to searching a product and Its too difficult to differentiate among them what to consider and what to eliminate. In 2013, I think alike Google, yahoo, bing and other general Search Engine, there might be a chance to boom Shopping Search Engine as like as “Where-To_Buy.in”

    An e commerce website is what every business (big or small) will have to own and run in the not too distant future. It has already started with more and more shops closing since the supermarket and internet age. People in the 21st century now crave the convenience of shopping from their homes. Nice article!

    Very good online shopping sites.
    But I need to share my feeling here, I don’t see anything special , they all do the same thing.

    I heard about a new startup from Canada who built a genius search engine for online shopping, I think it’s called Bloompa

    I found this bloompa.com.br but this is not them…

    I will throw my 2 cents in here. Take a look at www.shopgeniusapp.com as it lets you price compare right from the page you are on without going to an additional price comparison site. Why not do it all in one step? Take a look.

    One thing I didn’t see mentioned was the value of affiliate based price comparison websites such as FindersCheapers.com. An affiliate based price comparison website will charge a merchant ONLY when a sale is made and will allow the merchant to reverse compensation when an order is not fulfilled.

    More info is available here:

    For boosting the Online Shopping traffic on your site, a few things must be kept in mind. Using comparison shopping engines for this purpose is a good option. Send as many products to each engine as possible, and then be patient. It takes some time to build enough data to identify areas of optimization.

    Mark you forgot to mention that all of these engines only compare products at standard retail prices. Online shopping is about finding the best deals and discounts. To use your rubics cube example the only time a comparison shopping engine is useful is if I can find the cube on sale for $3 with free shipping on new egg or amazon and buy it together with my whey protein for the $50 15% discount coupon.

    When do we get to that point of shopping bliss? At www.slycut.com we are trying to do just that. Connect you to your online deals and do comparison shopping in one search.
