WHAT CHANGED

A strong product, spread too thin. We focused it.

The problem

  • Ad spend was scattered across a 30+ ASIN catalog of color variants, with no clear hero to concentrate rank behind.
  • TACoS ran above 17% while several well-reviewed variants received almost no traffic at all.
  • Sales were volatile month to month, making inventory planning and payout forecasting unreliable.

The strategy

  • Identify the proven hero listing — the best-selling cuticle trimmer converting over 74% of sessions — and fund it first.
  • Restructure PPC so the hero drives category rank while low-cost campaigns defend each color variant.
  • Scale spend into the strongest month, then hold efficiency: TACoS fell from 17.1% to 14.1% as sales grew.
OUR PROCESS

Four moves, run in sequence.

1

Audit & baseline

Mapped all 30+ ASINs against margin, sessions and conversion to find where profit actually came from.

2

Concentrate

Shifted the ad budget behind the hero listing instead of spreading it evenly across every variant.

3

Scale the peak

Pushed spend into May demand — sales grew 55% MoM and orders rose 58% in a single month.

4

Protect profit

Tightened bids as rank compounded: TACoS fell three points while net profit hit $29.4K in the peak month.
