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.
Why this matters for paid acquisition
Paid advertising in 2026 is shaped by privacy restrictions (Apple ITP, ATT, third-party cookie deprecation), platform attribution gaps (30-60% conversion path loss), and the rise of incrementality-validated measurement. Concepts like this one connect tactical campaign work to the strategic measurement frameworks that survive privacy changes and produce defensible ROAS.
