The 10 Best Comparison Shopping Engines (and How To Use Them)

As an eCommerce business owner, your primary goal is to increase revenue while reducing expenses — and utilizing comparison shopping engines can help you reach these goals. In this guide, we’ll address some of the most common comparison shopping questions, including what are comparison shopping engines and how to use them. We’ll also cover:

What Are Comparison Shopping Engines?

Comparison shopping engines (CSE) or comparison shopping websites are avenues for accumulating information on products, including prices, from various eCommerce companies. A single page then displays this information based on the search information entered by a potential buyer. Buyers can compare details such as shipping options, service, and price from various eCommerce retailers. They can then select the one that best meets their needs.

Utilizing comparison shopping engines allows you to put products and services you are offering directly in front of buyers searching for those items. Potential customers are not using comparison shopping websites to window-shop. They have most likely already made up their minds as to what they want to purchase; they are now looking for the best deal. This creates an ideal audience for promoting your eCommerce store.

Why Use Comparison Shopping Engines? 

There are a number of reasons to use CSEs, including:

  • Visitors to comparison shopping websites are qualified leads, as they have already decided to search out the product they are looking up. This results in a higher probability they will complete a purchase.
  • Comparison shopping engines have mastered SEO and are generally near the top of Google rankings. By utilizing these websites, you benefit from their high visibility and placement.
  • Many comparison shopping websites also have loyal followers, which introduces you to a broader audience.

The Impact of Comparison Shopping Engines on Sales

It’s important to understand what comparison shopping engines are so you can decide if using them will benefit your business model. For instance, they will most likely force you to lower your prices. There are three critical factors you need to understand before deciding to use comparison shopping engines.

  • Becoming the “Low Price Leader:” Price is a key factor for potential buyers when browsing comparison shopping websites. If you are continuously lowering prices for your products while other eCommerce retailers are doing the same, you might end up restricting your overall cash flow.

  • Not standing out: You might experience difficulties standing out among your competitors, as you are more likely to be offering similar products at similar pricing.

  • No customer loyalty: Buyers looking for bargains are the primary types of consumers using comparison shopping websites. This means if you are not offering the lowest price, you will most likely lose that customer.

By selecting specific items to feed to comparison shopping engines, you can benefit from them without focusing solely on having the cheapest product. There are two types of products that are best to do this with:

  1. Unique-to-you items: If you sell a product that no one else currently does, you will be able to include it on your product feed without having to lower its price.

  2. Alternating products: By selecting a few products that you feel comfortable lowering prices on and then rotating these items frequently, you can attract new customers that will hopefully remain loyal to you.

Amazon then creates ads for the products based on the information you provide in the product file. Once you establish a budget, the ads featuring your products will go live and you will pay per click.

How To Choose Which Comparison Shopping Engines To Use

Once you understand what comparison shopping engines are, you will need to select the ones that will work best for your eCommerce business. They are not all the same, and some will produce a better ROI (return on investment) than others for your eCommerce business.

If several of your competitors are using a certain comparison shopping engine, then the targeted traffic you desire will already be in place, but the competition for the sale will be high. If there are no competitors on a comparison shopping website, the traffic might be lower, but you are more likely to get potential buyers. The more comfortable you become working with comparison shopping engines, the more you will develop and fine-tune the skills required to price and market your products effectively.

To further narrow down which CSE is right for your business, you can ask yourself the following questions:

  • What type of channel do you want to utilize?
  • What kind of products do you sell?
  • Are your competitors using a CSE? If so, what kind?

CSE Pricing Models and Costs

Generally, comparison shopping engines charge eCommerce retailers either per action or per click-through. You will need to research an individual provider or contact them to determine which pricing model works best for your eCommerce business while fitting your budget. Here's a quick breakdown of the two pricing models we just mentioned in the meantime:

  • Pay-Per-Action: You will pay a certain percentage from any sale that results from a click-through on the comparison shopping website. With this model, you only pay when you sell a product as a direct result of it being on the comparison shopping website.
  • Pay-Per-Click: You pay a bid or set fee any time a potential buyer clicks on one of your product links. This is regardless of whether that person completes a purchase.

How To Get Listed & Optimize Your Products

Here are a few tips to help your products get listed on CSEs:

  • Create Merchant Accounts: Sign up for merchant accounts on popular CSEs like Google Shopping, Shopzilla, or PriceGrabber.
  • Product Feeds: Provide product data feeds to the CSEs. These feeds should include information like product title, description, price, and availability.
  • Data Feed Format: Ensure your data feed is in the correct format and adheres to the specific requirements of each CSE.
  • Optimize Data Feeds: Regularly update and optimize your data feeds to keep product information accurate and up to date.
  • Product Images: Include high-quality images of your products in your data feed. Images play a crucial role in attracting potential customers.
  • Pricing and Shipping Information: Clearly specify pricing, shipping costs, and delivery times in your data feed.

When it comes to optimizing your products, here are some things to keep in mind:

  • Keywords: Use relevant keywords in product titles and descriptions to improve visibility and search rankings on CSEs.
  • Product Reviews and Ratings: Encourage customer reviews and maintain high product ratings, as this can impact your CSE rankings and trustworthiness.
  • Category and Attribute Selection: Place products in the most relevant categories and provide accurate attributes to improve search accuracy.
  • Landing Pages: Ensure that the landing pages for your products are user-friendly and provide essential information for customers.
  • Inventory Management: Keep track of inventory and update your data feeds accordingly to prevent displaying out-of-stock items.
  • Promotions and Discounts: If applicable, advertise promotions or discounts to attract more buyers.
  • Competitor Analysis: Keep an eye on what your competitors are doing on CSEs and adjust your strategies accordingly.
  • Quality Scores: Some CSEs use quality scores to rank products. Work on factors like click-through rates and conversion rates to improve your scores.
  • Mobile Optimization: Ensure that your product listings are mobile-friendly, as many shoppers use mobile devices to compare prices and products.

Remember that optimizing your products on comparison shopping engines is an ongoing process, and regular monitoring and adjustments are essential for success.

A Warning on CSEs Before Listing Your Products

While there are benefits to using comparison shopping engines, they are not good fits for everyone. Certain components of comparison shopping campaigns might create difficulties for eCommerce businesses that don’t have technically fluent individuals or departments. Having fewer than 100 products available on comparison shopping engines will make it challenging for an eCommerce company to gain traction within the platform, as well.

There are, of course, exceptions. Asking yourself these questions can help you determine if comparison shopping campaigns will work for your eCommerce business:

  • What is your technical ability? How easily are you able to create new shopping or data feeds and export them?
  • Do you have a large number of products? Best practice recommends you have a minimum of 500 products; you should also take into consideration your average order value (AOV).
  • Are you pricing your products correctly? Buyers searching comparison shopping websites are getting increasingly savvy at comparing competing products and locating the best deal; offering products priced too high or products that buyers are not looking for will create a barrier to sales.

Understanding what comparison shopping engines are, determining which ones best fit your eCommerce business, and learning how to get products listed on price comparison websites are important components of being an eCommerce business owner — use this guide to do all the above with ease.
