The One-Two Punch Strategy: How Ecommerce Merchants Use Spillover Traffic to Scale Beyond Amazon
The landscape of modern digital commerce is increasingly defined by a complex tug-of-war between independent brand identity and the sheer logistical dominance of marketplace giants. Sean Stone, a veteran ecommerce strategist and founder of the agency Spillover Commerce, has proposed a tactical framework designed to navigate this tension. Stone argues that the most sustainable path to growth for contemporary merchants is not to choose between a dedicated brand domain and Amazon, but to employ a "one-two punch" strategy: building a profitable, branded Direct-to-Consumer (DTC) site while simultaneously capturing the inevitable "spillover" traffic that migrates to Amazon.
This strategic pivot comes at a time when the ecommerce sector is grappling with rising customer acquisition costs (CAC) on social media platforms and a saturated marketplace environment. Stone, who has spent years managing Amazon advertising campaigns, suggests that the traditional "Amazon-only" or "DTC-only" models are becoming increasingly fragile. Instead, he advocates for a symbiotic relationship where the branded site serves as the primary engine for storytelling and high-margin sales, while Amazon functions as a high-trust fulfillment and conversion secondary channel.
The Evolution of the Spillover Strategy
The methodology championed by Stone is rooted in nearly a decade of high-level marketplace management. The chronology of his professional trajectory mirrors the broader shifts in the ecommerce industry. Stone began his career in 2017, managing Amazon advertising campaigns as an agency employee during a period when the platform’s advertising console was still in its relative infancy. In 2021, he transitioned to entrepreneurship, launching his own firm under the name Stone’s Goods.
By January 2024, the firm underwent a significant rebranding to Spillover Commerce. This name change was more than aesthetic; it reflected a fundamental shift in how successful brands interact with the Amazon ecosystem. The "spillover" concept acknowledges a well-documented consumer behavior: shoppers often discover a brand through social media or a dedicated website but choose to finalize the purchase on Amazon to take advantage of Prime shipping, existing payment credentials, and a perceived guarantee of customer service.
Stone’s agency now focuses on two primary client profiles: Shopify-based brands that find Amazon difficult to navigate but recognize its market share is too significant to ignore, and Amazon-native sellers looking to diversify their revenue streams and build long-term brand equity off-platform.
The Consumer Trust Factor and Market Reality
The rationale behind the spillover strategy is supported by significant market data regarding consumer behavior. Amazon currently accounts for approximately 40% of all US ecommerce sales, and its Prime membership program boasts over 200 million members globally. For these consumers, the friction of purchasing from an unknown third-party website—entering credit card details, creating an account, and paying for shipping—is often a deterrent.
"Consumers love Amazon shipping. They trust it," Stone noted during a recent industry discussion with Eric Bandholz. This trust is often insurmountable for emerging brands. Even if a brand’s website offers a superior aesthetic experience, the consumer’s priority often lies in the reliability of the "last mile" delivery. By maintaining a presence on Amazon, brands can capture the sales that would otherwise be lost to competitors when a shopper leaves the brand’s primary site to search for the product on the marketplace.
However, this strategy requires a nuanced approach to brand management. Eric Bandholz, a prominent figure in the DTC space, raised concerns that many merchants feel Amazon "trashes" their brand by surrounding high-quality products with "cheap, junk products" and data-driven sellers who prioritize spreadsheets over brand storytelling. Stone acknowledges this gap, suggesting that the skill sets required to win on Amazon—which favors conversion rate and price competitiveness—are often the opposite of those required to win on Shopify and Meta, where emotional resonance and brand identity are paramount.
Platform-Specific Offers: A Tactical Deep Dive
To maintain brand integrity while leveraging Amazon’s reach, Stone recommends the implementation of platform-specific offers. Rather than offering an identical catalog across all channels, merchants should differentiate their value propositions.
A strategic framework for this "one-two punch" includes:
- The Flagship Experience (Shopify): The branded domain should offer the "full solution." This includes product bundles, exclusive items, loyalty programs, and the comprehensive brand narrative. This is where the merchant maintains the highest margins and owns the customer data.
- The Entry-Level or "Spillover" Offer (Amazon): The Amazon presence should feature a version of the product, perhaps a single item rather than a bundle, or a specific SKU designed for the marketplace environment. This ensures that when a customer searches for the brand on Amazon, they find a legitimate listing rather than a competitor’s "knock-off," but they are still incentivized to visit the main site for the premium experience.
A notable case study in this approach is the fitness equipment brand Gymreapers. Despite competing in the highly commoditized "wrist strap" category, Gymreapers generates significant revenue on Amazon—upwards of $10,000 per month on a single item—even when competitors offer similar products at half the price.
Analysis of Gymreapers’ strategy reveals that they use Meta (Facebook and Instagram) and TikTok to drive traffic not necessarily to Amazon, but to their own domain where they sell high-priced powerlifting bundles. The "spillover" occurs when consumers, influenced by the brand’s social media presence, search for "Gymreapers" directly on Amazon to purchase individual items. By maintaining a strong brand identity off-platform, they are able to command a 50% price premium on the marketplace compared to generic competitors.
The Limitations of Amazon Bundling and Organic Ranking
A common misconception among marketplace sellers is that the same marketing tactics used on DTC sites—such as complex bundling—will translate to Amazon success. Stone argues the opposite. On Amazon, the algorithm is heavily weighted toward organic ranking, which is driven primarily by the conversion rate of a specific Product Detail Page (PDP).
Because a single, clearly defined item typically has a higher conversion rate than a complex bundle, Stone advises sellers to focus on high-converting, single-product offers to maintain organic visibility. While bundling is possible on Amazon, it often fails to perform as well as the "hero" products that drive the majority of the traffic. This reinforces the need for the branded site to be the home of the "full experience," while Amazon serves as the high-velocity distribution point for individual SKUs.
Strategic Diversification for Amazon-First Sellers
For sellers who began their journey on Amazon, the transition to a branded website is often fraught with difficulty. Stone identifies three pillars necessary for a successful transition:
- Amazon Product-Market Fit: The product must already have a proven track record of sales and positive reviews on the marketplace.
- Meta Market Fit: Not all products are suitable for social media advertising. While a standard household mop might sell well via Amazon search, a "cool robot vacuum" or a lifestyle-oriented fitness product is more likely to capture attention on Meta’s visual platforms.
- Platform-Specific Offers: Transitioning sellers must create a reason for the customer to buy from their website rather than returning to the convenience of Amazon.
Furthermore, Stone emphasizes the importance of data ownership. Amazon famously restricts seller access to customer information, making it difficult to build long-term relationships. By maintaining even a low-volume Shopify site, sellers can engage directly with their most loyal customers, solicit feedback, and test new product concepts before a full-scale marketplace launch.
Broader Implications and Industry Outlook
The "spillover" model represents a maturation of the ecommerce industry. The era of "easy" growth on Amazon through basic SEO and arbitrage is largely over, as is the era of "cheap" customer acquisition for DTC brands. The future belongs to "omnichannel" merchants who understand that the modern consumer journey is non-linear.
By accepting that Amazon is a "secondary channel" for brand building but a "primary channel" for fulfillment and trust, merchants can protect their margins while maximizing their reach. This strategy mitigates the risk of platform dependency—where a single algorithm change or account suspension could bankrupt a business—while leveraging the massive infrastructure that Amazon has built.
As the digital marketplace continues to evolve, the integration of high-level brand storytelling with ruthless marketplace efficiency will likely become the standard operating procedure for the next generation of successful ecommerce entrepreneurs. Stone’s "one-two punch" provides a blueprint for this integration, suggesting that the most powerful tool a merchant has is not a single platform, but the ability to meet the customer wherever they choose to shop.
