In practice
Platform-reported ROAS is the most optimistic number in the account: it uses the platform's own attribution and counts revenue it did not necessarily create.
Compare it against blended ROAS — total revenue over total spend — and treat the gap as the size of the reporting illusion.
Why it matters
A 6x ROAS on a product with 20% margin loses money. Without margin in the calculation, the metric can justify unprofitable growth.
