The Advantages of Best Comparison Shopping Engines

Whether you're a veteran vendor or just starting out, you need to know which shopping engine is the best for your eСommerce operation. Choosing the best Shopping Engine is a very important decision for every eСommerce runner who is looking for a way to increase search rankings and online sales. A quality shopping engine is always crucial for the success of a Magento website: it can attract new customers, increase visibility and boost sales. At present, there is a broad assortment of Comparison Shopping Engines for all Magento based e-stores on the market, but how can you know which is best for you and what are the criteria you need to consider?

I conducted a study and ranked shopping engines for you based on these major metrics:

  • Revenue
  • Traffic
  • Cost of Sale (COS)
  • Conversion Rate
  • Average CPC
  • Merchant Response Ratings
  • Merchant Tools

Online merchants should make the most of this data and modify their marketing budget accordingly. The final goal is to increase the sales and product exposure on different sites.

Here is out list of the industry’s top 5 comparison shopping engines (CSE) for Magento based online merchants. All you need is to create a feed file and publish your products on your favorite platform.

1. Google Product Listing Ads

Google Product Search stole the top spot on the list in short order once it was converted into the paid Google Product Listing Ads / Google Shopping program. It has stayed in the top ever since according to nearly every noteworthy ecommerce metric. The constant increase in overall traffic has only made its ranking higher and better.


  • One of the greatest features of Google Product Listing Ads is that it has managed to maintain the lowest cost of sale while generating the most revenue and traffic compared to other search engines.
  • Likely the top advantage of this shopping engine for ecommerce merchants is that they can manually upload feeds or use an FTP to upload in bulk.
  • Google’s Merchant Center and Google’s AdWords – these are the two platforms that utilize Google's Shopping Engine. The Merchant Center is used for managing products, while AdWords is for managing Product Listing Ads (PLAs), setting a daily budget and adjusting bids. This makes your ads visible in both Google shopping sites and regular search results.
  • Google Shopping is available in various countries: the UK, France, Spain, Italy, Brazil, Netherlands, Japan, Australia, Germany and Switzerland.
