Selling online is simple. But choosing where determines your profit margins, brand control, and stress levels 12 months from now.
The fundamental question isn't "Can I sell online?" It's "Who owns the customer relationship?" When you sell on a marketplace like Etsy or Amazon, you rent space in someone else's shop. When you build your own website, you own the land—but you need to drive your own traffic.
This decision affects everything: your profit per sale, your ability to build a recognisable brand, your access to customer data, and your long-term scalability. Get it wrong, and you'll spend months fighting algorithm changes or haemorrhaging money to platform fees. Get it right, and you'll build a sustainable sales channel that compounds over time.
Most micro-businesses don't need both channels immediately. You need clarity on which one serves your goals, then the discipline to execute it properly.
What You'll Have When Done:
A finalized decision on your primary sales channel, supported by core trade-off analysis.
Time Needed: 25 minutes
Difficulty: Beginner
Prerequisites:
Decided Who You Actually Want as a Customer; Choose Your Website Platform.

Before you start, make sure you have:
Step 1: Confirm your primary product category.
Are you selling physical products, digital downloads, or services? Marketplaces work best for standardised physical and digital products. Services typically require a website for credibility and customisation.
Step 2: Assess your current audience size.
Do you have an existing email list, social media following, or customer base? If yes, a website makes sense—you already have traffic. If no, a marketplace provides immediate access to buyers.
Step 3: Calculate the percentage taken by fees.
Marketplaces typically take 10-20% per transaction plus payment processing fees. Website hosting costs £10-50/month regardless of sales volume. Run the numbers: at what monthly revenue does the marketplace become more expensive?
Step 4: Apply the Three-Question Test.
Step 5: Document your final choice.
Write down: "My primary selling channel is [Website/Marketplace/Hybrid] because [specific reason]." This becomes your reference point for the next 90 days.
You've completed this step when:
You have a documented decision on your primary channel and understand the core trade-off you've accepted (control vs. traffic).

Every online selling channel forces you to choose between two competing advantages:
Control means you own the customer relationship, set your own rules, control your branding, and keep your profit margins. This is the website path.
Traffic means you get immediate access to millions of active buyers without spending months on SEO or advertising. This is the marketplace path.
You cannot maximise both simultaneously when you're starting out.
A website gives you complete control over design, messaging, pricing, and customer data. You can build an email list, run retargeting campaigns, and create a brand experience that differentiates you from competitors. But you start with zero traffic. Every visitor must be earned through SEO, paid ads, social media, or word-of-mouth.
A marketplace gives you instant access to buyers actively searching for products like yours. Etsy has 96 million active buyers. Amazon has over 300 million. You don't need to drive traffic—the platform does it for you. But you pay for that traffic through fees (typically 10-20% per sale), you follow their rules, and you don't own the customer relationship. If the platform changes its algorithm or policies, your business can collapse overnight.

The fundamental trade-off between control (Website) and immediate traffic (Marketplace).
The question isn't which is "better." The question is which trade-off aligns with your business model, resources, and timeline.

Choose a website as your primary channel when:
The advantages:
You own everything. Customer data, email addresses, purchase history—it's all yours. You can build automated email sequences, create loyalty programmes, and develop repeat customer relationships without paying a platform fee on every transaction.
You control the brand experience. From the homepage design to the checkout flow, everything reflects your brand. You're not competing with 47 other sellers on the same product page.
You keep the profit. After hosting costs (£10-50/month) and payment processing fees (1.5-3%), the rest is yours. As you scale, your costs stay relatively flat while marketplace fees scale with revenue.
You build long-term SEO equity. Every blog post, product page, and customer review strengthens your domain authority. This compounds over years.
The disadvantages:
You start with zero traffic. Unless you already have an audience, you'll need to invest time and money into SEO, content marketing, paid advertising, or social media to drive visitors.
You're responsible for everything. Setting up your own ecommerce means handling hosting, security, payment processing, and technical maintenance. This requires either technical skill or budget to hire help.
Results take longer. Building organic traffic through SEO typically takes 6-12 months. Paid advertising requires budget and testing.
When to choose this path:
If you can answer "yes" to two or more of these, prioritise a website:

Choose a marketplace as your primary channel when:
The advantages:
Immediate access to buyers. List a product today, make a sale tomorrow. The platform's existing traffic and trust infrastructure do the heavy lifting.
Lower barrier to entry. Most marketplaces require minimal setup—upload photos, write descriptions, set prices. No need to choose a website platform or learn technical skills.
Built-in trust. Buyers trust established marketplaces. They're more likely to purchase from an unknown seller on Etsy than from a brand-new website they've never heard of.
Platform handles technical infrastructure. Payment processing, security, hosting, and (often) shipping logistics are managed by the platform.
The disadvantages:
You pay for every sale. Marketplace fees typically range from 10-20% per transaction, plus payment processing fees (another 2-3%). On a £50 sale, you might pay £8-12 in fees. Calculate your true take-home profit before committing.
You don't own the customer. The platform owns the relationship. You can't build an email list, run retargeting campaigns, or contact customers directly for repeat sales (policies vary by platform, but all restrict direct marketing).
You're subject to algorithm changes. Platforms constantly adjust their search algorithms and ranking factors. What works today might not work next month. Your visibility is never guaranteed.
You compete on the same page. On Amazon, your product listing appears alongside 20+ competitors, often in a race to the bottom on price.
Limited branding. Your storefront exists within the platform's design constraints. You can't fully control the customer experience or differentiate through design.
When to choose this path:
If you can answer "yes" to two or more of these, prioritise a marketplace:
The biggest downside of a Marketplace is lack of control over technical SEO and site speed. This is one of the pillars NetNav audits automatically across your whole site, ensuring that if you do build a standalone site, the foundations are solid.

Use this framework to evaluate your specific situation:
1. Cost Structure
Calculate the break-even point where marketplace fees exceed website costs.
Example: If marketplace fees are 15% and website costs are £30/month, you break even at £200/month in sales. Above that, the website is cheaper per transaction.
| Monthly Revenue | Marketplace Fees (15%) | Website Costs | Winner |
|----------------|----------------------|---------------|---------|
| £500 | £75 | £30 | Website |
| £1,000 | £150 | £30 | Website |
| £5,000 | £750 | £30 | Website |
2. Customer Ownership
Who owns the ability to contact the customer for future sales?
If your business model depends on repeat purchases or upsells, customer ownership is critical.
3. Branding Freedom
How much control do you need over the customer experience?
If you're building a premium or distinctive brand, branding freedom matters.
4. Scalability
What happens as you grow?
If you plan to scale beyond £5,000/month, website economics become significantly more attractive.

The most successful micro-businesses don't choose one channel forever. They use a Hybrid Strategy: start where you need to start, then migrate strategically.
The Hybrid Model works like this:

Common Problems and Fixes:
Problem: I sell services, not products, so marketplaces don't apply.
Fix: Focus the decision entirely on "Website" and use the criteria (cost, control) to select the best platform/builder instead. Services require credibility and customisation that marketplaces can't provide. Your decision becomes "which website platform" rather than "website vs marketplace."
Problem: The fees feel too high on the marketplace, but I need the built-in traffic.
Fix: Adopt the Hybrid Strategy where the Marketplace is treated as a lead generation channel, with the long-term goal of migrating customers to your website for repeat, higher-margin sales. Accept the first-sale fees as customer acquisition costs, then optimise for repeat purchases on owned channels.
Problem: I'm worried I won't be able to manage two platforms.
Fix: Choose only ONE channel to focus on for the first 90 days. Treat the secondary channel as a simple storefront, not a growth engine. You don't need to optimise both simultaneously. Master one channel first, then expand strategically.
