Selling on a marketplace — Amazon, Etsy, eBay, or any platform where the audience belongs to the platform rather than to you — is one of the fastest ways to get in front of buyers who are already looking to purchase. It's also a channel with a specific structural limitation worth understanding clearly: you're renting attention from an audience the platform owns, not building one of your own.
What Marketplaces Are Genuinely Good At
Marketplace traffic is often highly targeted by default, because the visitor arrived already searching with purchase intent, inside a platform built specifically around completing that purchase with minimal friction. This is a real advantage — it's some of the highest-intent traffic available, and it requires none of the work of building demand from scratch.
The Structural Limit
Most marketplaces are built to keep the transaction, and the customer relationship, inside their own ecosystem. Buyer contact information is often limited or withheld, repeat purchases are frequently routed back through the platform's own search rather than direct brand recall, and platform policies can change fee structures, search visibility, or seller standing with little notice. A business entirely dependent on marketplace traffic has, in effect, outsourced its customer relationships to a party whose incentives don't fully align with its own.
A Simple Framework
- Use the marketplace for what it's genuinely good at: reaching high-intent buyers who wouldn't have found you otherwise
- Where the platform allows it, use packaging, order communication, or included materials to invite customers to a direct relationship (a website, an email list, a loyalty program)
- Track what percentage of revenue depends on marketplace traffic specifically, the same way you'd track any other channel concentration risk
- Build a genuine direct channel in parallel, rather than treating the marketplace as the entire business
> Tip: Whatever a marketplace's rules allow for building a direct relationship with a customer after the sale, use it. Even a modest percentage of buyers moved into an owned channel meaningfully reduces total dependence on a platform you don't control.
Common Mistakes
- Treating marketplace traffic as guaranteed and permanent, without a plan if fees, policies, or visibility change
- Never attempting to move any portion of the customer relationship to an owned channel
- Ignoring marketplace-specific optimization (listings, reviews, platform-native search) while expecting the same results as a well-optimized independent site
- Building an entire business model with no channel outside the marketplace at all
Marketplaces are a legitimate and often highly efficient traffic channel — the mistake isn't using one, it's forgetting that the audience found there was never really yours to begin with, and building nothing outside of it as a result.
