eCPP (enhanced Cost Per Purchase)

A spend-rebate-adjusted efficiency metric (fallback/interpretation): cost per actual purchase after removing ad rebates/allowances, giving a more transparent view of true acquisition cost than ACOS/TACOS alone. Note: not currently established as a standard Amazon Ads term in the official documentation — presented here as a supplement to ACOS/TACOS.

eCPP (enhanced Cost Per Purchase)

Note: this definition is not live-verified against the official Amazon Ads docs (fallback/interpretation).

Example

Brand X spends 10,000 EUR and gets 500 true purchases after rebate adjustment → eCPP = 20 EUR/purchase (vs. 25 EUR raw ACOS).
