Read advertising results beyond ROAS
Use attributed revenue alongside contribution, returns and stock availability to make a clearer campaign decision.

The key decision: ROAS describes a revenue-to-spend relationship; it does not describe the whole business result.

ROAS divides attributed revenue by advertising spend. Record the source, attribution window and whether revenue includes cancelled or returned orders. Two reports can show different numbers without either describing incremental sales. Keep the comparison basis consistent before discussing a trend.
Work back from contribution
Subtract the variable costs relevant to each sale before considering advertising. These can include product cost, fulfilment and selling fees. Fixed overhead still has to be covered after advertising. A high revenue multiple can be insufficient for a product with a thin contribution margin.
Use a transparent example
Suppose an illustrative order produces 1,000 in revenue and 300 in contribution before advertising. Spending 250 to acquire that order leaves 50 before fixed overhead. ROAS is 4, while contribution after ads is only 50. At a 30% pre-ad margin, the simplified advertising break-even ROAS is about 3.33. Real results depend on the costs included.
Check operational constraints
Read campaign performance with sellable stock, delivery capacity and return patterns. A campaign for an unavailable variant can create customer disappointment while its dashboard still records clicks. Segment results where a different product mix or delivery outcome materially changes contribution.
Choose one testable next action
Change a defined part of the audience, creative, offer or buying journey and record what you expect to learn. Give the test a review point and keep other important changes visible. Use evidence from completed orders as well as ad reporting; avoid making a large budget decision from a short, unrepresentative period.
