Return on Ad Spend (ROAS)
Revenue generated per dollar of advertising spend — a campaign-level efficiency metric.
Return on Ad Spend (ROAS) is a marketing efficiency metric calculated as: revenue attributed to advertising ÷ advertising cost. A 4:1 ROAS means every dollar of ad spend generates four dollars in attributed revenue. ROAS is expressed as a ratio, multiplier, or percentage depending on context. Critical limitation: ROAS is only as accurate as the attribution model it's built on — platform-reported ROAS is typically overstated by 30-60% versus incrementality-validated ROAS because platforms take credit for conversions that would have occurred without the ad. Target ROAS varies by industry: e-commerce typically needs 3:1+ after CoGS; SaaS needs to account for LTV:CAC ratios over multi-year customer lifetimes. Empire325 builds ROAS measurement that accounts for attribution bias and shows incremental ROAS.
