The 15 Best Online Marketplaces for Ecommerce Retailers

By Tinuiti Team

As an ecommerce seller, your success relies heavily on the online marketplaces where you choose to list your products 

Your marketplace determines your audience, your reach, a good chunk of your overhead costs, and the policies and rules you have to abide by as a seller — and all of these can have a big impact on your reputation and your bottom line.

In this article, we’ll cover everything you need to know about the top 15 online marketplaces, how they work, and how to get set up on them.

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).
