Why POAS matters more than ROAS

  • ROAS ignores cost of goods — a 5x ROAS on a 70% COGS product still loses money
  • POAS (gross profit ÷ ad spend) tells you if ads are truly profitable
  • Ad blockers and ITP hide 20-30% of conversions — underreported ROAS causes underspending on profitable campaigns
  • sGTM restores full conversion visibility → ad platforms optimize toward actual profitable revenue
