How Automotive Brand Valvomax Grew Sales 94% by Focusing on What Converts

Valvomax is an automotive accessories brand built around a simple but powerful idea: make oil changes easier.

Its core product—a precision-engineered oil drain valve—removes the mess and complexity from a routine task, giving everyday drivers a cleaner, faster way to maintain their vehicles. That clarity of purpose has helped Valvomax stand out in a highly functional category and grow into a top-ranked brand on Amazon.

With a focused product ecosystem and strong customer demand, Valvomax had already proven product-market fit. The opportunity wasn’t to reinvent the business—it was to unlock the next phase of growth by aligning advertising with what was already working.

The Challenge

Valvomax had done the hard part right.

The product resonated. Demand was strong. The brand had earned a leading position in a competitive category. But as the catalog expanded, the advertising strategy began to drift away from that core strength.

Budget was spread across many SKUs, including many with limited conversion volume. For a category where fitment matters, this created friction—customers often needed multiple clicks to find the right product, and performance signals became diluted across too many touchpoints.

The result wasn’t poor performance—it was constrained potential.

Scaling spend became difficult because efficiency would drop as investment spread further into lower-performing areas. The brand wasn’t lacking demand—it needed sharper alignment between where demand existed and where budget was being deployed.

Why Quartile

To scale efficiently, the brand needed to concentrate investment around the products that were already winning—and build a structure that could support that focus at scale.

Quartile brought a disciplined approach to doing exactly that.

By combining campaign restructuring with continuous optimization, Quartile enabled Valvomax to move from fragmented performance to a system where every dollar had a clear role. This wasn’t about reducing complexity for its own sake—it was about removing what didn’t contribute to growth.

The Solution

Quartile started by making a deliberate shift: less coverage, more focus.

Sponsored Products campaigns for long-tail SKUs were paused, and over 90% of spend was reallocated to the three best-selling valve products. This immediately concentrated investment where conversion rates and demand were strongest.

But focus alone wasn’t enough—the structure had to support it.

Campaigns were rebuilt to clearly separate branded and non-branded traffic, enabling more precise bidding and budget control. This allowed Valvomax to protect high-intent demand while expanding into new customer acquisition through non-branded queries.

At the same time, Quartile worked directly alongside the Valvomax team to improve the shopping experience itself. By consolidating valve variations under a single parent listing, the brand reduced friction in the buying journey—making it easier for customers to find the right fit and convert.

This combination—media focus and retail readiness—created a system where performance could scale naturally. Traffic was cleaner. Conversion was higher. And optimization became faster and more reliable.

Results & Impact

The impact was immediate—and sustained over time:

• 60% month-over-month increase in total sales following the strategic shift  

• 94% year-over-year growth in total sales, demonstrating scalable momentum  

• 310% increase in ad-attributed sales, reflecting stronger demand capture  

• 32% improvement in Advertising Cost of Sales (ACOS), improving efficiency while scaling  

• Total Advertising Cost of Sale (TACoS) remained stable, confirming profitable growth  

Even as volume increased significantly, efficiency held steady—proving that growth was not coming from increased spend alone, but from better allocation.

These results reinforce a simple principle: when structure matches how customers actually shop, performance follows.

Ongoing Value & Future State

With a streamlined, high-performing structure in place, Valvomax is now positioned to scale efficiently as inventory allows.

Even during periods of constrained supply, the account has maintained stable performance—demonstrating the durability of a focused approach. As inventory stabilizes, the same framework can be extended to capture additional demand without reintroducing inefficiencies.

Quartile continues to support this growth, ensuring that performance remains disciplined as the business expands.
