The Marketplace Trap: 83% Volume, 95% Merchant Death

"60 % in Europe, 83 % globally." These figures from the latest Marktplatz Update by Michael Frontzek and Marcus Mokros^[1] have stirred up the e-commerce bubble. The message echoing through LinkedIn for days: Anyone not selling on Amazon, Otto, Kaufland, and Zalando no longer exists digitally.

The numbers are correct. But they only tell half the story. In this article, I'll show you why the marketplace euphoria is distorted, why 95 % of new Amazon sellers are gone after 12 months – and why brand SEO and your own owned audience are worth not less, but significantly more in 2026 than they were three years ago.

Core thesis: Marketplace volume is not the same as profit. Anyone building 100 % on rented ground doesn't have a business – they have a dependent sales package. Brand SEO + your own shop are the insurance policy against the algorithm.

1. The Data: Marketplaces Dominate Volume

Let's start with the facts. The eCommerce Data Base (ECDB) regularly publishes market share figures between marketplaces and standalone shops. Wortfilter and Händlerbund have picked up the numbers for 2025/2026^[2][3]:

The message is clear: Online marketplaces are the new infrastructure of digital commerce. Anyone seeking reach can hardly avoid platforms anymore. But this is precisely where the honest diagnosis of most marketplace consultants ends.

2. The Uncomfortable Truth: 95 % Seller Mortality

What most reports fail to mention: the brutal churn rate on Amazon. Every year, around 1 million new sellers worldwide launch on Amazon – roughly 2,500 to 3,700 per day. Yet after 12 months, almost nothing remains of this wave^[4][5]:

This means: the loud message "Get on Amazon, that's where the money is" is statistically speaking a lottery ticket, not a business model. The professional heavyweights win. Mid-sized businesses and small brands get ground up by the algorithm.

Important: These figures don't contradict Frontzek and Mokros. They refine them. The marketplace share of volume is growing because a few large players are consolidating the market – not because the average seller makes money more easily there.

3. The Margin Reality: Volume ≠ Profit

Let's look at what actually ends up in your account. Net margins differ structurally between marketplaces and your own shop (DTC, e.g. Shopify)^[6]:

The critical point: On a marketplace, you pay for every single sale. Commission (8 %–15 %, in fashion up to 45 %), FBA fees, advertising. In total, 30 %–50 % of gross revenue often goes directly to the platform. In your own shop, a repeat buyer costs you practically nothing.

Cost Structure: A Direct Comparison

4. The Bias Factor: Who Is Pushing the Marketplace Recommendation?

This is where it gets political. The current wave of recommendations toward marketplaces is massively distorted. Let's look at who is driving the narrative:

• Amazon consultants and agencies. Their business model is built on the platform's complexity. The deeper a seller is locked into Amazon, the longer they need external help for PPC, listings, and account management.
• Influencers and trade portals. Many are directly or indirectly funded by marketplace ecosystems – advertising, affiliate programs, data licenses.
• The data sources themselves. When reports come from platforms or from providers who license their API/data, caution is warranted. The incentive to portray "growth as inevitable" is built right in.

Key insight: The 83 % is evidence of the market power of the infrastructure – not of the success of the sellers on it. Reach is not the same as profitability.

5. Owned vs. Rented Audience: The Strategic Framework

This is the core of the matter. Every brand today has two types of audiences:

The test is simple: If your platform doubles its fees tomorrow – what happens to your cash flow? Anyone 100 % dependent on a marketplace isn't running a business in any real sense. They're a managed department head for a tech corporation, bearing full entrepreneurial risk but without access to their own customers.

6. Brand SEO: Why Classic Search Is Worth More Now, Not Less

Here comes the SEO twist that most marketplace consultants overlook: the more e-commerce concentrates on platforms, the more valuable visibility on your own domain becomes.

Three reasons why brand SEO won't die in 2026 – it will appreciate:

1. Google is the brand discovery stage. Even buyers who ultimately purchase on Amazon research on Google first: reviews, comparisons, explanations, Q&A. Anyone visible here influences the marketplace search via the brand name ("Brand X on Amazon").
2. AI search is becoming the new discovery layer. Google AI Overviews, ChatGPT, Perplexity, and Gemini cite brand domains that are well-structured and documented – not Amazon listings at random. Anyone without their own brand site with a clear architecture simply won't be mentioned in AI answers.
3. Direct brand searches are free traffic. Brand search volume is the only SEO channel that compounds with brand awareness – not with ad spend.

In practical terms: Anyone selling exclusively on marketplaces in 2026 is giving up brand control in two worlds – in platform search and in AI search. The free brand visibility that brand SEO delivers is the insurance policy against both dependencies.

7. The Hybrid Approach: Feed the Marketplace, Build Your Own Brand

The most successful brands combine both worlds. Marketplace and own shop are not an either/or question, but a question of role allocation:

Anyone who deliberately moves marketplace customers into their own ecosystem – via insert cards, QR code incentives, brand communications, brand search queries – converts expensive marketplace volume into profitable owned audience.

8. Diagnostic Checklist: Am I Too Dependent?

Seven questions you should answer honestly:

1. What percentage of my revenue comes from just one platform (Amazon, Otto, Zalando)?
2. What happens to my cash flow if that platform raises its fees by 20 % tomorrow?
3. Do I have my own domain that ranks in Google for my brand terms?
4. How many of my customers' email addresses do I actually own (not just Amazon order emails)?
5. Am I visible in AI Overviews / ChatGPT answers for my product category – or is it only Amazon?
6. How much direct brand traffic does my own domain receive?
7. If I were to sell my business today – what would the asset value be without the marketplace account?

Anyone who finds three or more of these questions uncomfortable has a concentration risk, not growth.

9. Conclusion: Profit Is Substance, Not Reach

The figures from Frontzek and Mokros are not a lie. They are evidence that the infrastructure of commerce is being centralized. But drawing the conclusion that every seller should go 100 % to marketplaces is precisely the distortion that the consulting industry lives off.

Revenue is visibility. Profit is substance.

In the long run, you only own what you control yourself: your own shop, your own data, your own brand relationship. Brand SEO in 2026 is not a hobby for marketing romantics – it is the structural insurance policy against the algorithm. Marketplace and owned audience are not a contradiction. But anyone who stops cultivating their own ground will eventually be evicted by the landlord.
