Marketplaces like Amazon capture 56% of e-commerce sales, but sellers keep only 70-85% after fees (Marketplace Pulse). Should you sell on marketplaces, build your own website, or both? The answer depends on your margins, brand ambitions, and growth stage. Here's the honest comparison — with real numbers.
In this guide, we cover marketplace vs own site economics, when each model works best, the hybrid approach used by successful brands, major marketplace platforms, migration strategies, and frequently asked questions.
Marketplace vs Own Website: Full Comparison
| Factor | Marketplace | Own Website | Winner |
|---|---|---|---|
| Traffic | Built-in (millions of visitors) | You must generate it (SEO, ads) | Marketplace |
| Margins | 15-30% commission per sale | 2-3% payment processing only | Own site |
| Brand building | Limited (marketplace brand dominates) | Full control over brand experience | Own site |
| Customer data | Marketplace owns it | You own everything | Own site |
| Competition | Listed next to competitors | You control the environment | Own site |
| Setup time | Days | Weeks to months | Marketplace |
| Customer loyalty | To the marketplace, not you | Email list, CRM, retention | Own site |
| Risk | Account suspension can kill business | You control everything | Own site |
The Economics: A Real Comparison
Let's compare a product sold at €50 with a €20 cost:
| Expense | Amazon | Your Own Site |
|---|---|---|
| Sale price | €50 | €50 |
| Product cost | -€20 | -€20 |
| Platform commission | -€7.50 (15%) | €0 |
| Payment processing | Included | -€1.50 (Stripe 3%) |
| Monthly subscription | -€1.30 (€39/30 orders) | -€1 (hosting amortized) |
| Marketing cost | €0 (built-in traffic) | -€5 (ad cost per sale) |
| Net profit per sale | €21.20 | €22.50 |
| Profit on repeat order | €21.20 (same) | €27.50 (no ad cost) |
When to Use a Marketplace
- Testing product-market fit — Low risk, quick feedback, validate demand before investing in a site
- High-volume, low-margin products — Built-in traffic compensates the commission on commodity items
- Starting out — Generate initial sales, reviews, and cash flow while building your brand
- International expansion — Access new markets without local marketing or infrastructure
- Seasonal products — Leverage marketplace traffic for holiday spikes without year-round marketing spend
When to Build Your Own Site
- Brand-driven products — Your story, experience, and community matter to customers
- High margins — Keep the 15-30% you'd lose in marketplace commissions
- Repeat business — Build an email list, loyalty programs, and direct customer relationships
- Complex products — Products that need education, configuration, or customization
- Niche authority — Position yourself as the expert in your specific category
The Hybrid Strategy
The smartest sellers use both channels strategically:
| Phase | Marketplace Role | Own Site Role | Revenue Split |
|---|---|---|---|
| Launch (0-6 months) | Main sales channel, validation | Brand presence, email collection | 80/20 |
| Growth (6-18 months) | Acquisition channel | Retention, higher margins | 50/50 |
| Maturity (18+ months) | Volume & discovery | Primary revenue, brand loyalty | 30/70 |

"We started selling our handmade candles on Etsy. Within 6 months, we had 200 5-star reviews and understood exactly what customers wanted. Then we launched our own site and included a card in every Etsy order: 'Order directly from us, get 15% off.' Today, 70% of our revenue comes from our own site with 25% higher margins. Etsy was the launchpad, our site is the business." — Illustrative example

Migrating from Marketplace to Own Site
- Build your email list first — Collect emails through package inserts, social media, and blog content before launching your site
- Don't abandon the marketplace — Keep it running while your site gains traction. Cutting off marketplace revenue too early is the #1 migration mistake
- Offer exclusive products on your site — Give customers a reason to visit your website instead of the marketplace
- Set up retargeting — Use Facebook/Google ads to remind marketplace customers about your brand and website
- Match the experience — Your site must be as easy to buy from as Amazon. Fast loading, simple checkout, clear shipping info
The Hybrid Strategy: Marketplace + Own Site
The question isn't always "marketplace OR own site" — the hybrid strategy combines the best of both worlds. Use marketplaces (Amazon, Etsy, eBay) to acquire new customers and test products, while gradually directing your audience to your own site where margins are higher.
The key is creating a differentiating experience on your site that marketplaces can't offer: personalized packaging, expert content, loyalty programs, premium after-sales service. Customers who experience this superior service become loyal direct buyers — no more paying marketplace commissions.
Beware the marketplace dependency trap. Sellers who generate over 80% of their revenue on a single platform are extremely vulnerable. An algorithm change, commission increase, or account suspension can destroy your business overnight. Diversify your sales channels as soon as possible — your own website is the only channel you control 100%.
Budget the transition smartly: invest the saved marketplace commissions into SEO and content marketing for your own site. Within 12 months, organic traffic can replace marketplace visibility — with 20-40% higher margins on every sale.
Making the Right Choice: Marketplace or Own Website
The marketplace-vs-own-website decision isn't binary — the most successful e-commerce brands use both channels strategically, understanding the strengths and weaknesses of each. Marketplaces (Amazon, Etsy, eBay) offer immediate access to millions of buyers but charge commissions of 15-30%, control the customer relationship, and can change the rules at any moment. Your own website gives you complete control, higher margins, and direct customer relationships — but requires you to generate your own traffic.
Start with the two-stage strategy: use marketplaces to validate product-market fit and generate initial revenue (Stage 1), then invest marketplace profits into building your own website and driving direct traffic through SEO, content marketing, and paid advertising (Stage 2). Never become more than 50% dependent on any single marketplace — diversification is not just smart business, it's survival insurance. Brands that depended entirely on Amazon have lost their businesses overnight when their account was suspended for policy violations.
Your own website should offer something marketplaces cannot: brand storytelling (your history, values, and manufacturing process), exclusive products or bundles, loyalty programs, personalized experiences (saved preferences, wish lists, custom recommendations), and direct customer support. These differentiators justify why a customer should buy directly from you instead of through a marketplace. Track customer acquisition cost and lifetime value per channel to make data-driven allocation decisions about where to invest your marketing budget.
Frequently Asked Questions
Can I sell on both platforms?
Absolutely — and you should. Start on a marketplace for visibility, then build your own site for brand building and better margins. Use the marketplace as an acquisition channel, your site as a retention channel.
How do I compete with Amazon on my own site?
Don't compete on price or selection. Compete on brand experience, storytelling, expertise, customer service, and community. Amazon can't replicate a personal brand. Your superpower is the relationship you build with each customer.
What about Etsy for artisans?
Etsy is excellent for initial visibility and validation. But commissions + listing fees eat profits over time. Many artisans start on Etsy, build a following and collect reviews, then transition customers to their own site where margins are 20%+ higher.
What if my marketplace account gets suspended?
This is the biggest risk of marketplace dependency. Amazon suspends accounts with little warning and opaque appeal processes. If 100% of your revenue comes from a marketplace, you're one algorithm change away from losing everything. Always build your own channel in parallel.
What's the best platform for my own site?
For e-commerce: Shopify for the easiest setup, WooCommerce for maximum flexibility on WordPress, or a custom-built site for maximum performance and brand differentiation. The right choice depends on your volume, technical skills, and growth ambitions.
Marketplaces rent you customers. Your own site builds an asset you own. The smartest strategy uses both: marketplaces for discovery and new customer acquisition, your website for relationships, repeat business, and building long-term brand equity.
