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

Gomag: Return on Ad Spend flat, Profit on Ad Spend improves after COGS + tracking

Index
  • Return on Ad Spend (revenue)
  • Profit on Ad Spend (profit)

Once COGS and click IDs feed conversion values, Smart Bidding shifts spend toward margin-positive Gomag SKUs.

Gomag ad-attributed profit mix

  • A — scale42%
  • C — optimize33%
  • X — exclude25%

A/C/X labels keep Shopping from scaling thin-margin Gomag accessories.

Connect Gomag via API — install click tracking and upload Profit on Ad Spend to Google Ads.

Why Gomag needs Profit on Ad Spend

Gomag catalogs and Romanian shopping ads often look profitable on Return on Ad Spend while acquisition cost, COD fees, and free shipping erase contribution.

Profit on Ad Spend ties each attributed Gomag order to real margin so Smart Bidding scales products that earn after ads — not just high-revenue SKUs.

Gomag Profit on Ad Spend setup

Connect once, install tracking, then let profit signals flow to ads.

  • In Profit Bid → Connect store, enter Gomag API shop and API key.
  • Sync the catalog and set or import COGS on bestsellers.
  • Install the Gomag click-tracking script from the connect instructions.
  • Link Google Ads (and Meta / TikTok / Microsoft / Pinterest as needed).
  • Enable Profit on Ad Spend conversion upload.
  • Turn on A/C/X labels after cost coverage is solid on ad-driven SKUs.

Why the click script matters

Gomag does not natively push every ad click ID into Profit Bid. The storefront script writes a ProfitBid note so orders carry gclid / gbraid / wbraid, fbclid, ttclid, msclkid, and epik for correct platform routing.
