Marketing ROI

Marketing ROI (Return on Investment) measures the efficiency and profitability of marketing campaigns by comparing revenue generated to marketing costs. It's calculated as ((Revenue - Marketing Cost) ÷ Marketing Cost) × 100. Positive ROI indicates profitable campaigns, while negative ROI signals ineffective spending. Multi-touch attribution models help accurately assign revenue to marketing channels. Effective ROI measurement requires proper tracking of customer journeys, conversion attribution, and lifetime value. Marketing ROI varies by channel, with organic SEO often providing the highest long-term ROI despite slower ramp-up times.
