That’s why we came up with this guide to help you navigate the noise and zero in on the online selling platforms that actually match your business goals. Let’s dive into the top 20 online marketplaces for you.

What is an online marketplace?

Selling online doesn’t necessarily require building everything an ecommerce website from scratch. 

With online selling platforms like Amazon, eBay, and Alibaba, which are nothing but a digital space where you tap into a bustling marketplace while being exposed to millions of high-intent shoppers.

These platforms bring you more than just customers; they offer powerful tools for listing products, managing orders, and handling customer questions. What’s more, online selling platforms give your brand a seat at the same table as the big players. 

Whether it’s a household name or an emerging brand, every product appears side by side in search results, leveling the playing field and giving you visibility you’d never get on your own.

Top 20 online selling platforms

Taking your business up to a global level sounds lucrative. Whether you’re a seasoned seller or just exploring an international online marketplace to sell, choosing the right portal can make or break your cross-border success.

With more than dozens of online marketplaces catering to different niches, audiences, and regions, the key lies in understanding where your products will thrive best.

These international online selling platforms come with a variety of tools to help sellers manage their listings, track performance, and ultimately increase sales, much like a Magento Hosting solution that offers a robust ecommerce infrastructure for businesses aiming for success.

To help you navigate this dynamic landscape, we’ve curated a list of the top 15 online selling platforms, each offering unique advantages to power up your global ecommerce game.

1. Amazon

Let’s talk about the king of online selling platforms, Amazon. Think of it as the ecommerce equivalent of the Amazon rainforest: massive, layered, competitive, and alive with opportunity. 

It is also your answer to “Which platform is best for ecommerce?”. With over 310 million global customers, it’s a marketplace where adaptability isn’t just nice to have, it’s non-negotiable.

To thrive in this best online selling platform, you’ll need sharp listings with high-resolution images, copy aligned with Amazon’s guidelines, and keywords that are well researched. 

Amazon’s built-in ad tools (like Sponsored Products) help boost early visibility, but without a clear strategy or a pro PPC agency like SellerApp you could burn through budget fast. 

With integrations for automation and access to a global audience, Amazon doesn’t just open doors, it opens runways for ambitious sellers.
