Pet House Amazon Case Study: TACoS 14.7% → 10.4% & +18.8% Sales Growth in 4 Months

Pet House (One Fur All) entered Q2 with rising ad costs, a -9.1% YoY revenue slide, and a TACoS far above target. Adverio was brought in to reverse course fast. Through aggressive waste removal, conversion-focused creative updates, and a Subscribe & Save growth push, the brand rebounded. In just four months, TACoS fell from 14.7% to 10.4%, ROAS rose from 3.1 to 3.8, and monthly sales climbed +18.8% — restoring both momentum and profitability ahead of schedule.

Product Category: Home & Kitchen > Pet Supplies

Brand Objective: Reduce TACoS to increase profitability while also reversing the declining topline.

The Challenge

April: Revenue –9.1% YoY at 14.7% TACoS (well above the 8% long-term goal).

May: Return to growth (+6% YoY, +12.9% MoM) with reduced 13.8% TACoS.

June: Further Profit Acceleration (+18.5% YoY), and continued lower 13.0% TACoS.

July: even with Buy Box loss, TACoS again reduced further down to 12.0%.

August and beyond: Topline continues to climb, and TACoS continues to trend favorably downward towards the 8% goal, faster than expected.
