In the high-stakes world of ecommerce, where a single pixel shift or a slight tweak in copy can mean the difference between a record-breaking quarter and a stagnant bottom line, Nate Lagos has emerged as a practitioner of the unconventional. A seasoned performance marketer with a decade of experience in the trenches of brands like Adapt Naturals and Original Grain, Lagos recently made waves by challenging one of the industry’s most entrenched habits: the "all-caps" headline.
His recent A/B test, which saw a 25% surge in conversions simply by shifting from aggressive uppercase headers to standard title-case formatting, serves as a microcosm of his broader philosophy. Lagos argues that for too many brands, the path to growth isn’t found in expensive, top-of-funnel ad spend, but in the granular, "bottoms-up" optimization of the user experience.
The Evolution of a Performance Marketer: A Chronology
Lagos’s journey into the heart of conversion rate optimization (CRO) was born from necessity and a keen analytical eye. His career trajectory reflects the modern shift in digital marketing—from broad-spectrum advertising to precision-engineered psychological messaging.
From In-House Strategist to Independent Founder
Lagos spent the better part of a decade sharpening his skills as an in-house marketer. During his five-year tenure at Original Grain, a brand specializing in wooden watches, Lagos faced a classic ecommerce conundrum: how do you sell a product that technically has no utility? In an age where smartphones serve as universal timekeepers, a watch is a luxury, a statement piece, and a symbol of status.
By pivoting the brand’s messaging to emphasize "accomplishment" rather than "timekeeping," Lagos helped drive a fivefold increase in revenue. This period defined his approach to copywriting: identifying the psychological "why" behind the purchase.
In 2024, Lagos launched his own passion project, Shootin’ Doubles, a brand catering to the whiskey-enthusiast demographic. The success of this side venture provided the catalyst for his next move. In May 2025, he founded Bottoms Up: Performance Copywriting & CRO, a boutique agency dedicated to testing brand copy across landing pages, emails, and ad platforms.
The Philosophy of "Bottoms-Up" Testing
The core of Lagos’s methodology lies in the inversion of the traditional marketing funnel. While many creative strategists prioritize "top-of-funnel" (ToF) activities—such as broad awareness campaigns and viral ad creative—Lagos contends that this approach is often disconnected from the actual point of purchase.
Defining the Bottoms-Up Approach
Lagos defines a "bottoms-up" strategy as testing copy as close to the "Add to Cart" button as possible. By focusing on product detail pages (PDPs), home page headlines, and the initial blocks of copy that a customer encounters, he aims to identify exactly what triggers a conversion or causes a bounce.
"Top-of-funnel is typically far from an actual purchase decision," Lagos explains. "Often, it’s not even related to the products. I want to know what entices someone to buy. Once we know that, we understand what buyers are really after. And once we understand that, we can go right to top-of-funnel ideas that attract the right kind of intent."
The Data-Driven Threshold
For testing to be meaningful, Lagos emphasizes that vanity metrics are insufficient. He advocates for high-volume testing—tens or even hundreds of thousands of site visitors—to reach statistical significance. His benchmark is an 80% or higher likelihood of a variant outperforming the control. Using tools like Intelligems to facilitate rigorous A/B testing, Lagos ensures that every change is backed by hard data rather than intuition.
Surprising Revelations: The All-Caps Phenomenon
The most striking example of Lagos’s "bottoms-up" efficacy involves the recent A/B test that yielded a 25% conversion lift. Like many marketers, Lagos had experimented with various formatting styles to draw attention to key headlines. However, the data suggested that the industry-standard use of all-caps—often used to signal urgency or importance—was actually hindering readability.
By testing a variant that utilized standard title-case capitalization, Lagos discovered that the improved legibility significantly reduced the friction for the visitor. "I recently tested it for a client who used all caps in headlines. I ran an alternative test that capitalized only the first letter of every word. It produced a 25% increase in conversions… I was surprised," he notes.
This finding aligns with broader UX research suggesting that while users scan quickly, their brains process "natural" sentence structures more efficiently than the jarring cadence of all-caps. It reinforces a fundamental truth in CRO: the best copy is invisible, allowing the value proposition to be absorbed without cognitive load.
Scaling Through Audience Expansion
When a brand reaches a point of saturation, where the core audience has been thoroughly captured, Lagos advises against the reflexive urge to launch new, capital-intensive products. Instead, he suggests looking at the existing product through the lens of a new demographic.
The Case for Gender-Inclusive Marketing
Lagos cites his experience at Original Grain as the gold standard for this strategy. When he discovered that 50% of the customer base was female, despite the marketing being exclusively targeted at men, he realized they were missing a massive opportunity. The strategy shifted: they began marketing the watches as premium gifts for men, crafted by women.
Within a short period, women accounted for 80% of the customer base. "Hire a woman," Lagos advises those looking to break into new demographic markets. He credits his colleague, Sarah Levinger, with coaching him on the nuances of gift-giving psychology. Understanding that women were purchasing these watches as a gesture of appreciation for their partners allowed the brand to tailor its messaging specifically to the pre-Father’s Day and holiday seasons, effectively expanding the brand’s reach without altering the core product.
Implications for the Future of Ecommerce
The implications of Lagos’s work are clear: the future of high-performance ecommerce lies in the marriage of psychological insight and rigorous scientific testing. As the digital landscape becomes increasingly crowded and the cost of advertising continues to climb, the brands that survive will be those that master the art of the "small win."
The Call to Action for Brands
For brands struggling to scale, the takeaway is twofold:
- Prioritize the "Bottom" of the Funnel: Before spending more on ads, ensure that your landing pages and product descriptions are mathematically optimized to convert the traffic you already have.
- Audit Your Assumptions: Whether it is the use of all-caps, the tone of your voice, or the demographic you are targeting, challenge the "standard practice." If a 25% lift can be found in a simple capitalization change, imagine the growth potential hidden in your current copy.
Final Thoughts
Nate Lagos’s approach is a reminder that in an industry obsessed with the next "big thing" in AI or algorithmic ad bidding, the most effective tool in a marketer’s arsenal remains the clear, human-centric message. By focusing on the "bottoms-up," brands can build a foundation that not only converts but resonates.
