A marketplace is a platform where many independent sellers list products for sale to the platform's own buyer base, versus a DTC (direct-to-consumer) website where you own the storefront and are responsible for bringing your own traffic. Amazon, Walmart Marketplace, eBay, Etsy, and TikTok Shop are all marketplaces in this sense — the platform owns the audience and the checkout, and you are one of many sellers competing for that audience's attention.

The core trade-off

Marketplace: you get access to a large, already-searching buyer base and built-in trust (buyers trust "Amazon" or "Walmart" more readily than an unfamiliar new website), in exchange for a referral fee on every sale, less control over the customer experience and data, and — on marketplaces like Amazon and Walmart — the possibility of sharing a single product page with other sellers of the same item (see Buy Box / Featured Offer, Explained).

Your own website: full control over branding, customer data, and pricing, in exchange for having to generate all your own traffic from zero, and full responsibility for the technical and trust infrastructure a marketplace provides for free (payment processing, buyer trust, mobile-optimized checkout, fraud screening).

The two marketplace models you'll encounter

Not all marketplaces work the same way underneath, and it's worth knowing the difference before you assume "listing a product" means the same thing everywhere:

  • Shared-catalog marketplaces (Amazon, Walmart): one product page can exist per unique item, and multiple sellers "offer" against that same page. Whoever wins the Buy Box/Featured Offer gets the sale by default. You may not control the title, images, or description if another seller created the listing first.
  • Individual-listing marketplaces (eBay, Etsy, TikTok Shop): each seller's listing is its own separate page, even if ten other sellers sell an identical or near-identical item. Visibility is driven by search ranking and paid promotion rather than winning a shared offer slot.

This distinction matters enormously for strategy. On a shared-catalog marketplace, a new seller can be technically "live" with zero visibility because a more established seller is winning the Buy Box on every relevant page. On an individual-listing marketplace, your listing is always visible somewhere in search — the question is only how far down the results it sits.

Why marketplaces exist at all

A marketplace solves a two-sided matching problem: buyers want a wide selection without visiting a hundred different websites, and sellers want access to buyers without having to acquire every single one themselves. The marketplace's whole business model is charging sellers a fee (see How Do Marketplaces Make Money?) for solving that matching problem — providing traffic, trust, payment processing, and often fulfillment, all bundled into one place.

A worked example: the same product, two channels

Imagine a $25 kitchen gadget you're launching for the first time.

On a marketplace: you create a listing, and within days it can start appearing in search results to buyers who are already typing "garlic press" or a similar query into the search bar. Some of those buyers convert on day one, because the platform already has their saved payment method and their trust. Your job is almost entirely about the product page (title, images, price) and inventory — not about generating demand from nothing.

On your own website: the identical product, on a Shopify store you just launched, gets zero organic visitors on day one. No one is searching "yoursitename.com/garlic-press" because no one knows the site exists yet. You have to run paid ads, build an email list, or use social media to manufacture the same discovery a marketplace gives you automatically — and every one of those visitors has to independently decide to trust a brand-new website with their payment details.

This is the single biggest reason almost every new ecommerce seller starts on a marketplace rather than a standalone site: it compresses months of audience-building into a listing that can be searchable in days.

Why most sellers use both eventually

Marketplaces are usually the faster path to real sales and reviews for a new product because they solve the "how do buyers find me" problem you'd otherwise have to solve yourself. A DTC site becomes more valuable as a complementary channel once you have some brand recognition and want a lower-fee, higher-control channel alongside marketplace sales — see Marketplace vs. DTC: A Full Comparison.

Common misconceptions

  • "A marketplace listing is basically a free storefront." It isn't free — the referral fee (commonly in the 8-15%+ range depending on category and platform) plus, in most competitive categories, some level of advertising spend are the real cost of the traffic you're renting.
  • "I own my listing the way I'd own my own website." On shared-catalog marketplaces especially, you often don't fully own the page — the marketplace can change policies, other sellers can offer against your listing, and the platform can suspend your selling privileges at its discretion.
  • "Once I'm approved, the hard part is over." Approval is the beginning, not the end — winning visibility (search ranking, Buy Box, ad placement) is an ongoing, competitive effort, not a one-time setup task.

FAQs

Do I need my own website before I can sell on a marketplace? No. Most marketplaces let you apply and sell without ever having a standalone website. Many successful sellers launch on a marketplace first and build a DTC site later, if at all.

Can I sell the exact same product on multiple marketplaces at once? Yes, and most growing sellers eventually do (see Multichannel Inventory Allocation once you're managing stock across more than one channel). Just be aware that pricing consistency across channels matters — see MAP Policies, Explained and general price-parity expectations.

Is it cheaper to sell on my own site than on a marketplace? Not necessarily — the marketplace's referral fee often replaces costs (paid traffic, payment processing, fraud tooling) you'd otherwise pay for separately on your own site. The real difference is usually about who owns the customer relationship, not which is cheaper in isolation.
