It is series time! One topic that we haven’t really talked much about in our blog are comparison-shopping engine sites. I have worked with multiple online retailers that have seen great success with this type of online advertising. So I want to take this series as an opportunity to dive deeper into the mystery of comparison-shopping.

In my first blog post of this series I tried to give an overview of what comparison-shopping engines are, why it can be important for online retailers and how to get started. Today I want to look at the top 10 shopping platforms and how your business could benefit from them. This related article shows an overview of CSE rankings for the first quarter of 2013.

Google PLAs (CPC)

Once a free service, Google Product Search is now transitioning to Google Shopping. We have already put together some material on how to sign up for Google PLAs as well as how to optimize. In terms of traffic volume, revenue numbers and conversion rates, Google PLAs continue to dominate the market. They are also in the top spot when it comes to cost of sale statistics. Google PLAs are integrated with Google’s pay-per-click platform AdWords and can therefore also be shown on standard Google search results. You need to sign up for Merchant Center and upload your product feed either manually or by using a FTP to upload in bulk. Here is an example of what a data feed needs to contain as well as what the data feed specifications for Google PLAs are.

Nevertheless, retailers still need to consider this CSE as it currently lists around 70 million products of various retail verticals and millions of visitors are reviewing the site on a monthly basis. Shoppers tend to use Pronto to look for low pricing of products as well as search the top performing merchants of different verticals. Whole feed processing can be done via FTP.

Bing Shopping (CPC)

Just as Google does, Bing Shopping offers a comparison-shopping platform with product listings appearing on Bing search results pages. As with the other CSEs, Bing compares product information, prices and reviews of consumers as shoppers are searching for specific products. In order to be able to use Bing Shopping, merchants need to sign up for a Microsoft Advertising adCenter account (here). While Bing Shopping received great feedback on providing customers with friendly results, it is important to know for merchants, that product feeds won’t be accepted during high-traffic shopping seasons. Here is a link for a sample data feed as well as further data feed specifications.

TheFind (Free)

As opposed to the other comparison-shopping engines in this post, setup and display of product listings on TheFind is free of charge. There is no feed submission, but merchants can allow TheFind bot to crawl product pages for their products to be showcased on TheFind. This CSE exhibits product details, coupons as well as local searches for merchant listings. Additionally, shoppers benefit from personalized results which can provide new product discoveries to them.

All in all, there is a great variety of comparison-shopping engines on the internet and it is only a matter of fact of establishing the goals merchants want to achieve with this online marketing channel. In one of my next articles, I want to focus on three comparison-shopping engines and how merchants can use them for their own benefits. Please feel free to leave me a comment with which CSE you want to hear more about. Otherwise, I will have to choose!
