Background

The strategy

Mighty Products sells mostly B2B products on Amazon. The goal was clear: improve return on ad spend and reduce ACoS. Rather than relying only on manual keyword campaigns, we built a unique strategy around Amazon's four automatic targeting groups, close match, loose match, complements and substitutes, run at tight bids to protect return on ad spend. The strategy campaign delivered a 20.46 ROAS at a 4.89% ACoS, and the account stayed highly efficient overall at 11.54% ACoS.

What we did

  • Activated all four automatic targeting groups: close match, loose match, complements and substitutes
  • Held bids tight at £0.10 to protect ROI while still capturing volume
  • Kept top-of-search exposure under 5%, letting low-cost placements drive purchases
  • Monitored each targeting group's ACoS and scaled the most efficient ones
