What are price comparison engines?
Comparison shopping engines are channels for collecting product information, including pricing, from participating retailers and then displaying that collective information on a single results page in response to a shopper’s search query. This lets shoppers compare prices, shipping options, and service from multiple retailers on a single page and choose the merchant that offers the best overall value.
For example, let’s say I’m looking for a Rubik’s Cube and want to see what my options are, or maybe find the best price. I can go to Google Shopping (one of the most popular CSEs around) and initiate a search. Here’s what comes up:
For ecommerce merchants, price comparison shopping engines are an opportunity to put your products in front of very interested buyers. These aren’t people glancing at a virtual storefront like a window shopper at the mall. Price comparison site users typically have already made the decision to buy and are simply looking for the lowest price. With their high intent to purchase, comparison shoppers often are an ideal audience for promoting your products.
How do price comparison sites work?
On the consumer side, price comparison sites work much like a search engine—the difference being price comparison engines will show products side-by-side and how they stack up against one another in terms of pricing. Typical search engines generally serve up straightforward results without sorting by price or showing comparisons.
On the business side, each price comparison site is a little different. Essentially, you pay a certain fee, submit the required content (product photos, URL, price, description, etc.), and list your products. Your products will then show up for relevant searches along with comparable products, ranked by price.
This is helpful for informing your pricing strategy. You don’t want to be priced too much above similar products, but you need to make sure you charge enough to turn a profit.

1. Google Shopping
Google Shopping is probably the largest and best-known comparison shopping engine. Products submitted to Google Shopping will also be displayed in standard Google search results and are integrated with Google Ads, the pay-per-click platform.
Google also launched a beta benchmarking tool for product prices on Shopping ads. This tool displays three specific metrics to help you see where you stack up against the competition:
- Average product price: the average price of a product when your ad showed or when your ad was competitive in an auction.
- Benchmark product price: the average click-weighted price for a product across all businesses that advertise that product with Shopping ads
- Benchmark product price difference: the percentage difference between your product’s average product price and the benchmark product price

Listing your products on this platform grants you access to Connexity’s retail performance marketing network, which provides hands-on help with campaign setup and maintenance. Plus, there are no long-term contracts or sign-up fees, so you can pull a product at any time if it’s not generating any revenue.
When you list your products on PriceGrabber, you’ll also be listed on Yahoo Shopping, which is a nice bonus.

6. Bing Shopping Campaigns
With tens of millions of product listings sorted into various retail verticals, and millions of visitors monthly, Pronto certainly merits consideration for any retailer’s CSE campaigns.
In addition to showing product and price comparisons, Bizrate allows customers to set price alerts for products they’re interested in. Bizrate is also a Connexity company, so merchants get those added benefits.
9. Amazon Sponsored Products
Amazon isn’t technically a comparison shopping engine, but it works in a similar fashion. When you register for Sponsored Products 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.

Idealo is a German CSE with a companion Shopify app. When you connect the Idealo Shopify app so it can generate a CSV file or data feed of all your products, it will then list those products on its site, according to the data you have in the backend of Shopify.
The cost of price comparison shopping engines
Most CSEs are going to charge you per click-through or per action. With pay-per-click, sellers pay a set fee or bid each time a potential customer clicks on that merchant’s link. ShopMania uses PPC for its pricing model.
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 a fit for all businesses, so choose the one that works best for you.
Unfortunately, not all price comparison engines are transparent about pricing information, so you’ll need to find out what the going rates are on each platform for your particular industry.
Getting products listed on price comparison websites
Most CSEs 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 CSEs easier and in some cases, automatic. Regardless of how a feed is created, smart merchants will work to optimize descriptions and product prices to get the most sales possible.
What is the best price comparison app?
The Shopify App Store offers a variety of price comparison apps, each with different features. While some connect with your store and list products on CSEs, others add product comparison features directly to your website. Some of the best include:
- Price Comparison by Vishal
- Compare It!
- Product Compare
- Compare Products by Omega
- Kudobuzz Multichannel
- SmartFeed Product Feed Manager
1. Price Comparison by Vishal
The Price Comparison By Vishal app pulls in competitor pricing and displays it on your Shopify site, letting you promote how low your prices are and how expensive the items are elsewhere. Though you don’t want users to click away from your site, this app is unique in that those click-throughs turn into earned affiliate sales—so it’s not a complete loss.
Prisync is a backend tool that lets Shopify store owners spy on competitor pricing. Adjust your own pricing strategy accordingly or use the app’s dynamic pricing feature to automatically change yours based on the competitive landscape. You can also see stock availability, set email notifications, and export data in Excel.
Similar to Prisync, PriceMole tracks competitor pricing to inform your strategy. It also tracks stock levels, has dynamic pricing, and includes email alerts.
4. Compare It!
Compare It! displays a pop-up on your site that shows product comparisons for your own products. The pop-up is customizable, so you can change the colors, fields, and labels. You can also move around where the pop-up is displayed on the page so you don’t distract from the shopping experience.
5. Product Compare
Like Compare It!, Product Compare lets you stack up your own products against each other. Product Compare also makes these lists shareable, so shoppers can send them to friends and family for their opinions. It also aids in product discovery, suggesting similar products to compare.
6. Compare Products by Omega
The Compare Products by Omega app is similar to Compare It! and Product Compare in that it helps customers put your products side by side to choose which is the best for them. Each product page has a detailed chart depicting price, ratings, stock level, and variants.

Another Shopify app to list your products on third-party CSEs and marketplaces is Lengow. Lengow also incorporates social commerce, affiliate platforms, and ad retargeting. The tool comes with analytics reporting so you can optimize product listings to increase sales.
What’s the best price comparison site?
The best price comparison site really boils down to your ecommerce strategy. Different retailers need different things. What are you selling? Who are you selling to? Where do those shoppers look to compare prices? And what specific features are they looking for in that product?
You also have budget considerations. While CSEs aren’t the most transparent or straightforward with pricing information, you can test a few and see which generates a better ROI. Then you can focus your efforts there.
Grow your business with price comparison sites
If you have a competitive price point and a quality product to boot, price comparison engines are an effective customer acquisition tool.
Whether you compare your own products to one another or put them up against the competition, CSEs can be a great way to ease buyer hesitation and instill confidence in their purchase.
