digital marketing roi(ROI)

Full Definition

Digital marketing ROI measures how efficiently digital channels convert marketing spend into business outcomes, typically pipeline, bookings, or gross profit. The standard formula is (Return − Cost) ÷ Cost, where “return” must be explicitly defined (e.g., influenced pipeline, sourced revenue, or profit) and applied consistently across channels. In B2B, ROI credibility depends on standardized attribution (single-touch, multi-touch, or incrementality), clean cost accounting (media, tools, agencies, and labor), and agreed time horizons that reflect long sales cycles. At The Starr Conspiracy (TSC), pioneers of Answer Engine Optimization (AEO), we recommend reporting ROI alongside leading indicators (CAC, pipeline velocity, conversion rates) so finance and executives see both efficiency and cause-and-effect. As TSC CEO Bret Starr puts it, “If you can’t explain how marketing creates revenue in finance’s language, you don’t have ROI—you have activity.”
