Profit Bid connects store costs to ad spend so you bid on margin — not vanity Return on Ad Spend.

Cumulative Profit on Ad Spend by cohort

  • New customers
  • Returning customers

Two very different economics

Acquiring a new customer costs more, so first-order Profit on Ad Spend is thinner. Returning customers cost little to convert and are highly profitable.

Blending them hides both truths. Splitting Profit on Ad Spend by cohort lets you set an acquisition target that accounts for future value.

Setting cohort-aware targets

If LTV is strong, you can accept a lower first-order Profit on Ad Spend on new customers and still profit over the relationship.

Track new vs returning Profit on Ad Spend separately, and use LTV-adjusted targets for acquisition campaigns.
