Attribution & true performance
AI builds your weekly true-performance sheet from raw spend and Shopify totals; a real holdout test tells you what was actually incremental.
Every platform reports a rosier number than reality, so their ROAS figures added together often "credit" more revenue than your store made. Blended MER and a simple holdout are how you tell attributed performance from incremental performance, which is what separates brands that scale profitably from brands that scale their own losses.
