In the rapidly evolving landscape of digital retail, e-commerce merchants are increasingly caught between two competing forces: the high-margin potential of a direct-to-consumer (DTC) branded website and the massive, albeit restrictive, reach of the Amazon marketplace. For years, industry experts have debated whether a brand should focus on one or the other.
Sean Stone, founder of the newly rebranded consultancy Spillover Commerce, argues that this binary choice is a false dilemma. Instead, he proposes a "one-two punch" strategy: merchants should prioritize building a profitable, branded Shopify site while simultaneously leveraging Amazon as a secondary channel to capture high-intent, "spillover" traffic.
The Evolution of Spillover Commerce: A Chronology
The philosophy behind Spillover Commerce was born from years of hands-on experience in the trenches of Amazon advertising.
- 2017: Sean Stone begins his career managing Amazon advertising campaigns, gaining early insight into the mechanics of the platform’s search algorithms and the limitations of a "marketplace-only" business model.
- 2021: Stone launches "Stone’s Goods," an agency dedicated to helping brands navigate the complexities of Amazon’s ecosystem.
- 2023–2024: After observing a growing trend where successful Amazon sellers struggled to build long-term brand equity, Stone pivots his service model.
- January 2024: The firm rebrands to "Spillover Commerce," signaling a strategic shift toward a hybrid model that integrates DTC website growth with optimized Amazon presence.
The agency’s current mission is to bridge the gap between "spreadsheet-savvy" Amazon sellers, who often view products as mere commodities, and brand-focused DTC marketers who prioritize customer experience and storytelling.
The Strategic Framework: The ‘One-Two Punch’
The core premise of Stone’s strategy is that Amazon’s greatest strength—its unparalleled consumer trust—is also its greatest trap for brands. "Consumers love Amazon shipping. They trust it," Stone explains. "If something doesn’t work out, they know they’ll be made whole. That trust is insurmountable for many brands."
However, relying solely on Amazon leads to a commoditized existence where price wars are the only path to visibility. The Spillover Commerce methodology suggests a dual-channel approach:
1. The Primary Pillar: The Branded Shopify Site
The Shopify site serves as the "full solution." It is where the brand tells its story, offers complete product bundles, and captures valuable customer data. This is the platform where merchants own the customer relationship, allowing for personalized email marketing, loyalty programs, and high-margin sales.
2. The Secondary Pillar: The Amazon "Spillover" Channel
Amazon acts as a capture point for customers who are already searching for the brand by name or for products in a specific category. Stone advises that brands should not list their entire catalog or their "best" offers on Amazon. Instead, they should offer a simplified, specific version of their product. This prevents "cannibalization," where a customer who would have purchased from the brand’s site is lured away by lower prices or competitive alternatives on the marketplace.
Supporting Data: Why Brand Equity Matters on Amazon
The question often arises: Can a brand actually charge a premium on Amazon, where price-sensitive bargain hunters congregate?
Stone points to the case study of Gymreapers, a powerlifting equipment company. Despite operating in a category saturated with inexpensive, "no-name" Chinese commodities, Gymreapers successfully generates significant monthly revenue on Amazon for a basic product like wrist straps.
The secret? Their Amazon sales are a byproduct of their external marketing efforts. By utilizing Meta ads and TikTok influencers to drive traffic to their own website for high-ticket bundles (belts, knee wraps, and full lifting kits), they build brand authority. When a consumer discovers the brand through these channels, they often search for the company name on Amazon to take advantage of Prime shipping. Consequently, Gymreapers can charge 50% more for their wrist straps than their competitors, purely because they have successfully established themselves as a premium brand off-platform.
The Technical Challenges of Marketplace Success
While the strategy sounds intuitive, the execution requires a nuanced understanding of platform dynamics.
Amazon Search vs. Meta Discovery
Stone highlights a critical reality: what wins on Amazon is the opposite of what wins on Meta (Facebook/Instagram). Amazon is an intent-based search engine; shoppers are looking for a specific solution. Meta is a discovery-based environment; shoppers are looking for entertainment or inspiration.
"You don’t advertise a mop on Meta, but you do advertise a cool, innovative robot vacuum cleaner," Stone notes. Sellers who fail to understand this distinction often burn through marketing budgets by trying to force "Amazon-style" ads into social media feeds.
The Myth of Bundling for Acquisition
Many merchants mistakenly believe that creating complex product bundles on Amazon will drive new customer acquisition. Stone’s experience suggests otherwise.
"Bundling on Amazon doesn’t really work," he says. "What drives organic ranking on Amazon is the conversion rate. The best play is to have a high-converting offer on a single product detail page and drive as many organic sales as possible." According to Stone, complexity reduces conversion. A clean, singular offer that solves one problem efficiently is more likely to rank, which in turn leads to higher organic visibility.
Implications for Future E-commerce Growth
The shift toward a hybrid model has significant implications for how e-commerce brands should allocate resources and define success.
Bridging the Data Gap
A common complaint among Amazon-first sellers is the lack of customer data. Amazon keeps the customer, not the brand. Stone advises that even if a brand’s priority is Amazon, they must maintain a web presence to facilitate direct engagement. By using the website as a feedback loop—asking customers about their preferences, their pain points on Amazon, and their product suggestions—brands can gather the qualitative data necessary to iterate their product line.
Platform-Specific Offers
The future of successful e-commerce lies in "platform-specific offers." Brands that treat Amazon and Shopify as two separate storefronts with different audiences will thrive.
- On Shopify: Offer the full, premium experience, loyalty perks, and comprehensive bundles.
- On Amazon: Offer the entry-level "gateway" product that builds trust through fast shipping and reliability.
The Role of the Agency
As the digital landscape becomes more sophisticated, the role of agencies like Spillover Commerce is evolving from simple advertising management to holistic business strategy. For founders, the path forward is clear: do not be trapped by the limitations of a single platform. Instead, build a brand that is strong enough to survive off-platform, and use the "spillover" traffic from the world’s largest marketplace to subsidize that growth.
Conclusion
The "one-two punch" is not merely a marketing tactic; it is a defensive and offensive posture designed for long-term sustainability. By building a robust brand on a proprietary domain and maintaining a strategic, secondary presence on Amazon, merchants can mitigate the risks of platform algorithm changes while maximizing the reach of the world’s most powerful retail engine.
As Sean Stone puts it, the brands that will dominate the next decade are those that stop asking "Shopify or Amazon?" and start asking "How can I make them work together?"
