Which advertising metrics showcase the amount made for every dollar spent on advertising?

The correct answer is "Return on ad spend (ROAS)." Return on ad spend (ROAS) is the advertising metric that showcases the amount of revenue made for every dollar spent on advertising. It is calculated by dividing the total revenue generated from ads by the total cost of those ads, and it helps advertisers assess the profitability of their ad campaigns. A higher ROAS indicates a more efficient use of advertising spend, as it means that more revenue is being generated for each dollar invested. In contrast, click-through rate (CTR) measures the effectiveness of an ad in generating clicks, and advertising cost of sales (ACOS) focuses on the cost of advertising relative to sales, but neither directly measures the revenue generated per ad spend like ROAS does.
