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

Resulting profit: target return on ad spend vs tProfitOnAdSpend

  • Profit @ revenue target return on ad spend
  • Profit @ profit-fed target Profit on Ad Spend

Same campaign, same engine. Feeding profit values turns a flat profit line into a compounding one.

Track Profit on Ad Spend automatically from your store — upload profit conversions and scale winners with A/C/X labels.

It is the same strategy, different fuel

There is no separate 'Target Profit on Ad Spend' button in Google Ads. You achieve it by uploading profit-weighted conversion values into a Target return on ad spend strategy.

The algorithm then bids up high-profit auctions and bids down thin-margin ones — de facto profit bidding.

The outcome over time

Under revenue target return on ad spend, profit tends to plateau because the system happily scales revenue on low-margin SKUs.

Under profit-fed tProfitOnAdSpend, profit compounds as spend concentrates on margin-rich orders.
