Return on Ad Spend
Return on Ad Spend (ROAS) is a foundational performance marketing metric measuring gross revenue generated for every dollar invested in advertising campaigns. Expressed as a multiplier (e.g., 3.5x) or percentage (350%), it reflects top-line advertising efficiency across platforms like Meta, Google, and TikTok.
Marketing Efficiency Ratio (Blended ROAS)
Marketing Efficiency Ratio (MER), also known as Blended ROAS or Marketing Efficiency Rating, measures overall marketing efficiency by dividing total store revenue across all channels by total combined marketing spend.
Customer Acquisition Cost
Customer Acquisition Cost (CAC) is the total dollar cost required to acquire a single new paying customer. It encompasses advertising spend, creative production, software, and marketing team overhead divided by total new customers acquired.
Profit on Ad Spend
Profit on Ad Spend (POAS) measures gross profit generated for every advertising dollar spent. Unlike traditional ROAS which measures top-line revenue, POAS reveals bottom-line profitability after deducting product costs (COGS) and variable fees.
