Why Your ROAS Is Wrong: The Hidden Gaps in Shopify Attribution

From Polar Analytics

  • Ad platforms routinely over-report ROAS by 2 to 3x versus first-party, click-based measurement.
  • Every platform (Meta, Google, TikTok) claims credit for its own attributed conversions, so adding up platform ROAS numbers double counts sales.
  • Blended ROAS, total revenue divided by total spend, is the number that cannot be inflated this way.
