Why doesn't my Meta ads ROAS match my Shopify sales?
Relying solely on Return on Ad Spend (ROAS) to judge advertising performance leaves store owners wondering why cash is still tight. Furthermore, incomplete data tracking between Shopify and Meta Ads results in missing purchase events. This makes attribution difficult and causes the reported ROAS to look much worse than the actual results.
