How a Pet Nutrition Brand Restored Amazon Ad Efficiency with Quartile

This premium pet nutrition brand produces natural treats for dogs and cats using simple, minimally processed ingredients. As both the brand owner and manufacturer, the company sells directly on Amazon and competes in a category defined by intense competition and high advertising pressure.

For the brand, advertising is not simply about generating traffic. It must translate into efficient, profitable revenue while supporting long-term growth across a large and diverse product catalog.

Maintaining that balance requires constant alignment between retail conditions and advertising investment.

The Challenge

In late 2025, advertising performance across the account began to deteriorate.

At first, the signals looked familiar: rising costs, weakening efficiency, and advertising returns drifting away from target levels.

But the deeper issue wasn’t media performance.

It was retail readiness.

Across a significant portion of the catalog, Buy Box ownership had become unstable. Products that historically converted reliably were now intermittently losing eligibility to capture the sale.

Advertising continued to generate traffic and shopper engagement. But when customers clicked, the brand was not always the seller positioned to complete the purchase.

The result was a subtle but damaging disconnect: advertising was still doing its job, but the retail environment had changed.

Without realizing it, the brand was increasingly paying to drive traffic to products it could not consistently convert.

What looked like a media efficiency problem was actually a retail readiness problem.

Why Quartile

Solving the issue required more than adjusting bids or budgets.

The brand needed a partner capable of understanding how retail conditions and advertising performance interact on Amazon—and more importantly, how to operationalize that insight at scale.

Quartile approached the problem differently.

Instead of asking how campaigns could generate more traffic, Quartile focused on a more fundamental question:

Where is advertising actually able to convert demand?

By analyzing the relationship between Buy Box ownership and advertising performance across the catalog, Quartile identified the core structural issue: media investment was not consistently aligned with the brand’s ability to capture the sale.

The opportunity was not simply to optimize campaigns.

It was to realign the entire advertising system with the brand’s retail reality.

The Solution

Quartile rebuilt the advertising strategy around a single operating principle:

Advertising should only amplify demand where the brand can reliably convert it.

To make that principle actionable, Quartile introduced a Buy Box–driven investment framework across the account.

Instead of treating every product as equally eligible for advertising, media investment began responding to the underlying retail conditions of each listing.

Products with stable Buy Box ownership became the primary drivers of demand capture. These listings received the majority of advertising investment, ensuring that shopper interest translated directly into revenue.

Products with less consistent eligibility were treated more cautiously, preserving selective visibility while avoiding inefficient traffic.

And when Buy Box ownership dropped below reliable levels, advertising support was removed entirely.

What emerged was a fundamentally different approach to Amazon advertising.

Campaigns were no longer optimized purely for traffic or keyword performance.

They were optimized for conversion eligibility.

In other words, advertising investment began following retail readiness.

This alignment is difficult to execute manually across dozens of ASINs and constantly shifting marketplace conditions. Quartile’s technology and strategic oversight made it possible to monitor eligibility signals and adapt investment decisions continuously.

Advertising stopped working against the retail environment—and began working with it.

Results & Impact

Once advertising investment was aligned with Buy Box eligibility, performance improved immediately.

• 34% increase in ad-attributed sales, driven by improved demand capture

• 21% improvement in Advertising Cost of Sales (ACOS) as inefficient traffic was eliminated

• 17% improvement in Total Advertising Cost of Sale (TACOS) restoring profitable advertising performance

• 6% improvement in cost-per-click (CPC) efficiency, reflecting cleaner participation in the auction

More importantly, the account regained structural stability.

Advertising was no longer reacting to performance fluctuations—it was operating within a framework designed to convert demand efficiently.

The lesson was clear: on Amazon, advertising performs best when it amplifies retail readiness rather than attempting to compensate for its absence.

Ongoing Value & Future State

With a retail-aligned advertising framework now in place, the brand is positioned to scale demand with greater confidence.

Quartile continues to monitor Buy Box ownership across the catalog and dynamically adapt campaign eligibility as marketplace conditions evolve.

This ensures that advertising investment remains consistently aligned with the products best positioned to capture demand—protecting efficiency while enabling sustainable growth.
