What Is Marketplace?
Website
Updated 18 September 2026
Quick Answer
A marketplace is a third-party platform (like Amazon, Etsy, or Not On The High Street) where multiple sellers list products, offering built-in traffic and trust in exchange for fees and less control than your own store.
Marketplace vs. E-commerce (Your Own Store) — What's the Difference?
| Marketplace | E | |
|---|---|---|
| Traffic | Built-in, from the platform's existing customer base | You must generate your own traffic entirely |
| Control | Limited — subject to the platform's rules and fees | Full control over branding, pricing, and customer relationship |
Why It Matters
- It offers immediate access to an existing customer base, which would otherwise take significant time and effort to build independently.
- The tradeoff is reduced control, ongoing fees, and often more direct competition on price with similar sellers.
How It Works
- A seller creates a listing on the marketplace platform.
- The platform's existing traffic discovers and potentially purchases the product.
- The seller pays fees (listing, transaction, or subscription) in exchange for this access.
Key Takeaways
- A marketplace offers built-in traffic and trust, in exchange for fees and reduced control.
- Many businesses use marketplaces alongside their own store, not instead of it.
- Building a distinct brand is harder within a marketplace's constraints.
Frequently Asked Questions
Should I sell on a marketplace or build my own online store?
Many businesses do both — a marketplace for built-in traffic and discovery, alongside an own store for more control and direct customer relationships.
Are marketplace fees worth it?
It depends on your margins and how much the built-in traffic is genuinely worth relative to building your own audience from scratch.
Can I build a brand on a marketplace alone?
It's more difficult, since the platform typically limits customization and controls the customer relationship — many businesses use marketplaces as one channel alongside their own branded store.
