Define the conversion before comparing a rate
An order, qualified lead or signup can be a conversion. Define the action and denominator, such as sessions, visits or users; they are not interchangeable. Compare like with like, and check absolute outcomes when traffic mix, campaigns or seasonality changes.
ROAS measures attributed value per ad dollar
ROAS compares reported conversion value with ad spend. Its meaning depends on value source, attribution window, refunds, lead quality and offline outcomes. Platform-reported value is not collected revenue or proof that ads caused the result.
Profit needs more of the business context
Profit includes costs beyond ad spend—margin, fulfillment, payment fees, returns and operations. A high ROAS can still mean poor profit. Choose metrics for the business objective and available downstream economics.
Use the metric that matches the decision
Choose the metric for the decision: campaign teams may need attributed value per ad dollar; finance, contribution after costs; site teams, quality-adjusted conversions. PPC or CRO analysis can help businesses diagnose the path from traffic to value.
Common questions
What is a good ROAS?
A good ROAS supports profit after the costs you include. The target depends on margins, attribution and objectives.
Can a higher conversion rate mean a better business result?
No. A higher conversion rate can still hurt economics when conversion quality, discounts or traffic mix change. Consider relevant value and guardrails, not the rate alone.
What does ROAS actually measure?
ROAS is attributed conversion value divided by advertising cost; it describes reported value per ad dollar, not net profit. A 4.0 ROAS means four dollars of tracked value for each dollar of ad spend. Check what the platform counts as value and which costs sit outside that ratio before using it to judge whether a campaign earns money. Sources and context
