As an e-commerce business, knowing where to promote your products can play a huge role in achieving your business goals. Having working knowledge of product listing ads (PLAs), marketplaces, and comparison shopping engines will help you get your products in front of more shoppers, leading to a boost in overall business and an improved return on investment.

PLAs provide your business with excellent exposure. These ads are integrated with search results on major, high-traffic sites such as Google, Bing and Amazon. They give the shopper an image, description and price of the product, as well as identification of your store by both name and URL.

Marketplaces make up nearly 35 percent of all e-commerce business. Marketplace transactions take place on the marketplace - not on your website. They run on a pay-per-action model, meaning businesses only pay when customers make a purchase.

Comparison shopping engines help businesses reach targeted shoppers, and allow shoppers to find products by price, features and selection. They run on a pay-per-click model, providing a cost-effective solution to attract more qualified impressions and traffic.

Here’s a list of 8 shopping engines you can use for your e-commerce business, courtesy of GoDataFeed:

• Google: With over 3.5 billion searches per day, Google shopping provides retailers with huge exposure for their products. They do so by channeling traffic from the world’s largest search engine based on search criteria. Google shopping can also show products on PLA’s and remarketing campaigns.
• Amazon: Amazon product ads (APAs) allow retailers to present their products to Amazon shoppers while maintaining control of the purchase process. This lets retailers merchandise related products and control the brand experience. APA costs-per-click are the lowest PLA’s in the industry, ranging between $0.10 and $1.35 on amazon.com.
