The 15 Best Online Marketplaces for Ecommerce Retailers (2023)

What is an online marketplace?

An online marketplace is an ecommerce site where multiple third-party sellers list their products. On online marketplaces, transactions are processed by the marketplace, not the sellers.

How do online marketplaces work?

Here’s a simplified explanation of what happens when a shopper makes a purchase from an ecommerce marketplace.

1. Shopper makes a purchase on an ecommerce marketplace

Let’s say shoppers get to the Amazon Marketplace (directly or via another site such as Google), browse, and ultimately select an item(s) via a product page. When the shopper goes to check out on Amazon, their order will be submitted through the Amazon marketplace.

2. The marketplace passes the order details along to the seller

When a shopper makes a purchase, the marketplace (in this example, Amazon) lets the third-party seller (in this example, Sony) know by sending the order details from the marketplace to the seller.

3. The third-party seller sends the customer the product

The third-party seller then handles fulfillment for that purchase. Different marketplaces have different fulfillment policies, but this is the basic structure of how online marketplaces work with third-party sellers.

Benefits of selling on an online marketplace

Why should you sell on an online marketplace?

One of the biggest benefits: pre-existing customer bases. Online marketplaces are already trusted by hundreds of millions of shoppers who check those marketplaces first when they need to buy something.

Selling on an online marketplace can also be easier and faster than building your own ecommerce website because the interface is built for you — which often makes it a better experience for shoppers who are already familiar with the site. Once you’re approved as a third-party seller on an online marketplace, you can simply create your product listings, then you’re ready to sell!

Many online marketplaces also offer third-party sellers opportunities to promote their products to shoppers, such as Amazon Advertising, and options to outsource order fulfillment, such as FBA (Fulfilled by Amazon).

How to sell on Alibaba: Alibaba can be an excellent marketing engine for suppliers, but new vendors should keep in mind that it can take years to rise to the top of Alibaba’s search results and account for the expense — so make sure that it’s worthwhile for your business before you get started.

If you do decide to sell your products on Alibaba, you’ll need to register for an account, establish your company profile, and list your products.

Pricing depends on the type of product you sell and the individual Alibaba portal you sell it on (there are many — including some that are even fee-free). There are also subscription and transaction fees in some cases.

While sellers can join for free, basic membership on Alibaba severely limits the number of products displayed as well as access to promotional tools, rendering it functionally useless to most companies hoping to expand.

Alibaba best practices:

• Given that Alibaba is a B2B website, their best-sellers are generally items that can be mass-produced and sold wholesale to replenish inventory for companies
