How a Supplement Brand Increased Amazon Traffic 522% with Google to Amazon

This immune support brand sells a focused range of mushroom-based supplements designed for both adults and children. Operating in a competitive category with strong seasonal demand, the brand relies on Amazon as its primary sales channel and competes through differentiated formulations and targeted health positioning.

The Challenge

The brand wasn’t struggling with conversion—it was struggling with reach.

Performance Max campaigns were effective at capturing existing demand, but growth had stalled. Traffic levels remained flat, and engagement metrics plateaued over multiple months.

The limitation was structural. The account was optimized to harvest demand, not create it.

Previous attempts to drive traffic outside of Amazon had failed to deliver sustainable results. Without a reliable way to educate new customers and introduce the product earlier in the journey, the brand remained dependent on a fixed pool of in-market shoppers.

To grow, the brand needed a way to expand demand—while still driving that demand back into Amazon where conversion happens.

Why Quartile

Quartile identified that the missing piece was not more optimization within Amazon—but a stronger connection between external discovery and Amazon conversion.

Through its Google to Amazon solution, Quartile enables brands to create demand off-Amazon while controlling how that traffic flows into product detail pages. This ensures that external traffic is not wasted, but instead becomes a measurable and scalable driver of Amazon performance.

For this brand, that meant building a system where Google campaigns didn’t just generate clicks—they generated qualified shoppers who were guided directly into Amazon with clear purchase intent.

This closed the loop between demand creation and demand capture.

The Solution

Quartile implemented a structured Google to Amazon framework designed to layer demand generation on top of existing performance campaigns.

The first phase established a baseline using Performance Max and Search campaigns directing traffic to Amazon. This created a clear view of existing demand capture and engagement levels.

Then, Demand Gen was introduced as the growth engine.

A dedicated Demand Gen campaign was launched to expand reach beyond in-market audiences, targeting users earlier in the journey. Instead of replacing the existing structure, this campaign was layered on top—adding incremental discovery while maintaining conversion efficiency.

Budgets were scaled gradually as performance validated, ensuring that growth remained controlled and sustainable.

Together, this created a full-funnel system:

• Demand Gen generated awareness and new traffic  

• Performance Max captured intent  

• Amazon converted demand  

This is the core of Quartile’s Google to Amazon approach—connecting external demand directly to Amazon outcomes.

Results & Impact

The impact extended across both Google and Amazon performance:

• 522% increase in product detail page views, significantly expanding Amazon engagement  

• 509% increase in click-throughs to Amazon, driving deeper traffic volume  

• 219% increase in Google clicks, with improved engagement efficiency  

These gains translated into meaningful business impact. The brand achieved its highest monthly sales on record, demonstrating that increased discovery directly fueled revenue growth.

The key takeaway: when demand creation is directly connected to Amazon conversion, growth becomes both scalable and measurable.

Ongoing Value & Future State

With Quartile’s Google to Amazon solution in place, the brand now operates with a connected acquisition strategy. External traffic is no longer experimental—it is a reliable growth lever.

Quartile continues to refine targeting, optimize campaign performance, and scale demand generation, ensuring the brand can sustain growth across peak seasonal periods and beyond.
